SoC PXA2xx Core

- ALSA: ARM: add Raumfeld audio support
Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
- ASoC: finally enable support for eXeda and CM-X300

wm8940 requires I2C.
- trivial: remove unnecessary semicolons

Control Midlevel

- Refresh patches to remove fuzz
- ALSA: remove unnecessary null check
This function is only called from snd_ctl_ioctl() and the file parameter
can never be null so there is no need to check it here.
We dereference file at the start of the function:
struct snd_card *card = file->card;
and it confuses static checkers to dereference a pointer before
checking it.
- control: use reference-counted pid
Instead of storing the PID number, take a reference to the task's pid
structure. This protects against duplicates due to PID overflows, and
using pid_vnr() ensures that the PID returned by snd_ctl_elem_info() is
correct as seen from the current namespace.
- control: remove snd_konctrol_volatile::owner_pid field
We do not need to save the ID of the process that locked a control
because that information is already available in the owner's file data.

PCM Midlevel

- Refresh patches to remove fuzz
- Refresh pcm_native.patch for changes of DMA handling
- Refresh vm_ops related patches
The patches got broken due to the upstream changes of vm_ops to the
const pointer. Refreshed now.
- Refresh pcm_natvie.patch
- ALSA: pcm - fix page conversion on non-coherent PPC arch
The non-cohernet PPC arch doesn't give the correct address by a simple
virt_to_page() for pages allocated via dma_alloc_coherent().
This patch adds a hack to fix the conversion similarly like MIPS.
Note that this doesn't fix perfectly: the pages should be marked with
proper pgprot value. This will be done in a future implementation like
the conversion to dma_mmap_coherent().
Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
- ALSA: pcm - fix page conversion on non-coherent MIPS arch
The non-coherent MIPS arch doesn't give the correct address by a simple
virt_to_page() for pages allocated via dma_alloc_coherent().
Original patch by Wu Zhangjin <wuzj@lemote.com>.
[Ralf mentioned: "The origins of this patch go back far further.
The oldest patch I could find which is a superset of this was written
by Atsushi Nemoto and various incarnations of it have been sumitted
to and reject by me a number of times through the years."]
A proper check of the buffer allocation type was added to avoid the
wrong conversion.
Note that this doesn't fix perfectly: the pages should be marked with
proper pgprot value. This will be done in a future implementation like
the conversion to dma_mmap_coherent().
Acked-by: Ralf Baechle <ralf@linux-mips.org>
- ALSA: pcm - define snd_pcm_default_page_ops()
Add a helper (inline) function as the default page ops. Any hacks wrt
the page address conversion will be applied in this function.
- ALSA: pcm - Use dma_mmap_coherent() if available
Use dma_mmap_coherent() for mmapping the buffers allocated via
dma_alloc_coherent() if available. Currently, only ARM has this function,
so we do temporarily have an ifdef pcm_native.c. This should be handled
better globally in future.
- sound: pcm: record a substream's owner process
Record the pid of the task that opened a PCM substream. For sound
cards with hardware mixing, this allows determining which process
is associated with a specific substream's volume control.
- control: use reference-counted pid
Instead of storing the PID number, take a reference to the task's pid
structure. This protects against duplicates due to PID overflows, and
using pid_vnr() ensures that the PID returned by snd_ctl_elem_info() is
correct as seen from the current namespace.
- ALSA: sound: Move dereference after NULL test and drop unnecessary NULL tests
In pcm.c, if the NULL test on pcm is needed, then the dereference should be
after the NULL test.
In dummy.c and ali5451.c, the context of the calls to
snd_card_dummy_new_mixer and snd_ali_free_voice show that dummy and pvoice,
respectively cannot be NULL.
A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@match exists@
expression x, E;
identifier fld;
@@
* x->fld
... when != \(x = E\|&x\)
* x == NULL
// </smpl>
- const: mark struct vm_struct_operations
* mark struct vm_area_struct::vm_ops as const
* mark vm_ops in AGP code
But leave TTM code alone, something is fishy there with global vm_ops
being used.
- ALSA: pcm - Simplify snd_pcm_drain() implementation
Simplify snd_pcm_drain() implementation and avoid unneeded array-
allocation for waitqueues. Instead, one waitqueue is used for the
first draining stream, and wait until all streams finished.
- ALSA: Re-export snd_pcm_format_name() function
Re-export snd_pcm_format_name() function to be used outside the PCM core.
As a first example, usbaudio is changed to use it now again.

RawMidi Midlevel

- Add O_DSYNC definition in rawmidi.c
Now O_DSYNC is used instead of O_SYNC in rawmidi.c.
- vfs: Implement proper O_SYNC semantics
While Linux provided an O_SYNC flag basically since day 1, it took until
Linux 2.4.0-test12pre2 to actually get it implemented for filesystems,
since that day we had generic_osync_around with only minor changes and the
great "For now, when the user asks for O_SYNC, we'll actually give
O_DSYNC" comment. This patch intends to actually give us real O_SYNC
semantics in addition to the O_DSYNC semantics. After Jan's O_SYNC
patches which are required before this patch it's actually surprisingly
simple, we just need to figure out when to set the datasync flag to
vfs_fsync_range and when not.
This patch renames the existing O_SYNC flag to O_DSYNC while keeping it's
numerical value to keep binary compatibility, and adds a new real O_SYNC
flag. To guarantee backwards compatiblity it is defined as expanding to
both the O_DSYNC and the new additional binary flag (__O_SYNC) to make
sure we are backwards-compatible when compiled against the new headers.
This also means that all places that don't care about the differences can
just check O_DSYNC and get the right behaviour for O_SYNC, too - only
places that actuall care need to check __O_SYNC in addition. Drivers and
network filesystems have been updated in a fail safe way to always do the
full sync magic if O_DSYNC is set. The few places setting O_SYNC for
lower layers are kept that way for now to stay failsafe.
We enforce that O_DSYNC is set when __O_SYNC is set early in the open path
to make sure we always get these sane options.
Note that parisc really screwed up their headers as they already define a
O_DSYNC that has always been a no-op. We try to repair it by using it for
the new O_DSYNC and redefinining O_SYNC to send both the traditional
O_SYNC numerical value _and_ the O_DSYNC one.

- sound: rawmidi: record a substream's owner process
Record the pid of the task that opened a RawMIDI substream.
- control: use reference-counted pid
Instead of storing the PID number, take a reference to the task's pid
structure. This protects against duplicates due to PID overflows, and
using pid_vnr() ensures that the PID returned by snd_ctl_elem_info() is
correct as seen from the current namespace.
- sound: rawmidi: fix opened substreams count
The substream_opened field is to count the number of opened substreams,
not the number of times that any substreams have been opened.
Furthermore, all substreams being opened does not imply that the next
open would fail, due to the possibility of O_APPEND. With this wrong
check, opening a substream multiple times would succeed only if the
device had more unopened substreams.
- sound: rawmidi: fix MIDI device O_APPEND error handling
Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 broke the
error handling code in rawmidi_open_priv().
If only the output substream of a RawMIDI device has been opened and
if this device is then opened with O_RDWR | O_APPEND and if the
initialization of the input substream fails (either because of low
memory or because the device driver's open callback fails), then the
runtime structure of the already open output substream will be freed
and all following writes through the first handle will cause
snd_rawmidi_write() to use the NULL runtime pointer.

- sound: rawmidi: fix checking of O_APPEND when opening MIDI device
Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 dropped the
check that a substream must already have been opened with O_APPEND to be
able to open it a second time.
This would make it possible for a substream to be switched to append
mode, which would mean that non-atomic writes would fail unexpectedly.
Cc: <stable@kernel.org>
- sound: rawmidi: fix double init when opening MIDI device with O_APPEND
Commit 9a1b64caac82aa02cb74587ffc798e6f42c6170a in 2.6.30 moved the
substream initialization code to where it would be executed every time
the substream is opened.
This had the consequence that any further opening would drop and leak
the data in the existing buffer, and that the device driver's open
callback would be called multiple times, unexpectedly.

- ASoC: Codec driver for Texas Instruments tlv320dac33 codec
Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo
audio DAC.
TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low
power audio playback.
The digital interface can use I2S, DSP (A or B), Right and Left
justified formats.
DAC33 has stereo analog input, which can be bypassed to the analog
outputs.
Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass'
mode (default) and nSample mode (FIFO is in use).
a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is
working synchronously as a normal codec (it needs constant stream of
data on the digital interface).
b) The nSample mode implementation uses one interrupt line from DAC33 to
the host:
Alarm threshold is set to 10ms of audio data (limit by the driver
implementation).
DAC33 will signal an interrupt, when the FIFO level goes under the
Alarm threshold.
The host will write to nSample register a value (number of stereo
samples), to tell DAC33 how many samples it should read in a burst from
the host. When the DAC33 received the number of samples, it disables the
clocks on the I2S bus. When the FIFO use again goes under the Alarm
threshold, DAC33 signals the host with an interrupt, and the process is
repeated.
- ASoC: TPA6130A2 amplifier driver
Driver for Texas Instruments TPA6130A2 stereo headphone

The driver provides playback gain control and also pre-defined
DAPM_HP widgets and DAPM routings for power management.
The DAPM_HP widget names are:
"TPA6130A2 Headphone Left"
"TPA6130A2 Headphone Right"
From soc machine drivers to use with the tpa6130a2 amplifier,
the tpa6130a2_add_controls has to be called, which adds the alsa
controls and the DAPM routing needed for the tpa6130a2.
After that the machine driver can connect the codec's output
with 'TPA6130A2 Left' and 'TPA6130A2 Right':
{"TPA6130A2 Left", NULL, "CODEC LEFT OUT"},
{"TPA6130A2 Right", NULL, "CODEC RIGHT OUT"},
Internally the left and right channels are powered separately.
When none of the channels are needed the amplifier is powered
down:
hard power: valid GPIO number is passed within platform data
soft power: Using the software shutdown of the amplifier

AC97 Codec

- ALSA: ac97_codec - increase timeout for analog sections to 5 second
I have a Soundblaster 16PCI. For many years, alsa has had a bug where
not all of the card's controls are detected (many alsa versions,
many kernel versions). In particular, Master Playback Volume is
usually not detected, and so I get no sound or extremely faint sound.
The problem has always been inconsistent: sometimes all of the controls
are detected correctly, and sometimes a partial set is detected. It works
correctly about 10% of the time.
Finally, I got around to tracking down the problem. When the driver
fails, it prints the kernel message "AC'97 0 analog subsections not
ready". This message is generated from the function snd_ac97_mixer()
in ac97_codec.c. The message indicates that the card failed to come
back after reset within the time limit. The time limit is
120 milliseconds.
I tried increasing the time limit to 1 second, and found that this
made the driver work about 70% of the time. I tried increasing it
to 5 seconds, and it now seems to work 100% of the time.
I expect that this change would be completely harmless for
existing cards that work, and would only introduce additional
delay for cards that do not work.

When the volume is changed continuously (e.g., when the user drags a

Apparently, the sound chip can get confused when we poll the I2C status
register too much, and fails to complete a read from it. On the PCI-E
models, the PCI-E/PCI bridge gets upset by this and generates a machine
check exception.
To avoid this, this patch replaces the polling with an unconditional
wait that is guaranteed to be long enough.

happened if the cs4236 module loading failed.
Fix this by adapting the snd_cs4236_create() to correctly work with

same as the snd_wss_create() if the chip is less capable than the cs4236.

Digigram VX Pocket driver

- pcmcia: rework the irq_req_t typedef
Most of the irq_req_t typedef'd struct can be re-worked quite
easily:
(1) IRQInfo2 was unused in any case, so drop it.
(2) IRQInfo1 was used write-only, so drop it.
(3) Instance (private data to be passed to the IRQ handler):
Most PCMCIA drivers using pcmcia_request_irq() to actually
register an IRQ handler set the "dev_id" to the same pointer
as the "priv" pointer in struct pcmcia_device. Modify the two
exceptions (ipwireless, ibmtr_cs) to also work this waym and
set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
(4) Handler is to be of type irq_handler_t.
(5) Handler != NULL already tells whether an IRQ handler is present.
Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
irq_req_t.Attributes.

things:
With the iMac 24-inch 3.06GHz Intel Core 2 Duo
everything seems to be working as it should,
although I have not looked into the microphone
(never really use one, nor have any apps to test,
my guess is it doesn't work, or I never figured out how
to get it to work).
With the iMac 24-inch 2.66GHz Intel Core 2 Duo
everything is the same as with the above machine
except I'm hearing a light scratchy/distortion noise
come out of the speakers when using headphones(above machine
does not do this).
Other than that the sound level is great(especially with good Dj headphones).

Also, add gameport support and remove an unused mpu field.
- ALSA: sscape: convert to firmware loader framework
The conversion solves the problem that firmware size was set to 64KB

- ALSA: hda - Fix mute sound with STAC9227/9228 codecs
On FSC laptops, the sound gets muted gradually when the volume is chnaged.
This is due to the wrong volume-knob widget setup. The delta bit (bit 7)
shouldn't be set for these devices.
This patch adds a new quirk to set the value 0x7f to the widget 0x24
instead of 0xff.

Dreamcast AICA sound (pcm) driver

- ALSA: snd-aica: declare MODULE_FIRMWARE

ES18xx driver

- ALSA: es18xx: code improvements
1. Set the third argument of the snd_device_new to not NULL, so there is
no warning about bug during chip detection. The third argument is not
used in this driver. It was changed in my previous patch.
2. Remove the fm_port and mpu_port fields from the snd_es18xx structure.
They can be converted to function arguments.
3. Remove the dmaN_size fields from the snd_es18xx structure. These
values are used only in pointer functions and can be easily calculated.
4. Remove the ctrl_lock spinlock which is used only in one read function
which is called once during chip initialization. There are many
writes to the same register and they are not protected on purpose
(see the comment ina the snd_es18xx_config_write()).
5. Use the first part of the text5Sources string table as the text4Soruces
table (they are the same).
6. Merge the same cases for the ES1887 and ES1888 when setting chip's caps.
7. Move the snd_es18xx_reset() to __devinit section.
- ALSA: es18xx: remove snd_audiodrive structure
Remove intermediate snd_audiodrive structure between
snd_card structure and snd_es18xx. This reduces size of
source code and binary driver.
- ALSA: es18xx: remove snd_card pointer from snd_es18xx structure
The snd_card pointer is redundant and code can be easily
changed to work without it.

FM801 driver

- sound: snd-fm801: autodetect SF64-PCR (tuner-only) card
When primary AC97 is not found, don't fail with tons of AC97 errors.
Assume that the card is SF64-PCR (tuner-only).
This makes the SF64-PCR radio card work "out of the box".
Also fixes a bug that can cause an oops here:
        if (tea575x_tuner > 0 && (tea575x_tuner & 0x000f) < 4) {
when tea575x_tuner == 16, it passes this check and causes problems
a couple lines below:
        chip->tea.ops = &snd_fm801_tea_ops[(tea575x_tuner & 0x000f) - 1];
Tested with SF64-PCR, but I don't have any of those sound or sound+radio cards
to test if I didn't break anything.

- intelhdmi - dont power off HDA link
For codecs without EPSS support (G45/IbexPeak), the hotplug event will
be lost if the HDA is powered off during the time. After that the pin
presence detection verb returns inaccurate info.
So always power-on HDA link for !EPSS codecs.
KarL offers the fact and Takashi recommends to flag hda_bus. Thanks!
- ALSA: intelhdmi - add channel mapping for typical configurations
IbexPeak is the first Intel HDMI audio codec to support channel mapping.
Currently the outstanding problem is, the HDMI channel order do not
agree with that of ALSA. This patch presents workaround for some
typical use cases. It gives priority to the typical ALSA surround
configurations, and defines channel mapping for them.
We may need better kernel+userspace interactive channel mapping scheme.
For example, in current scheme if user plays with the surround50 device,
the kernel is unaware of this and will still select the surround41
channel allocation and channel mapping..
Thanks to Marcin for offering good tips!
- ALSA: intelhdmi - channel mapping applies to Pin
HDA036-A specifies that the Audio Sample Packet (ASP) Channel Mapping
verbs apply to Digital Display Pin Complex instead of Converter.
With this fix, channel mapping is working as expected for IbexPeak.
Thanks to Marcin for pointing this out!
- ALSA: intelhdmi - accept DisplayPort pin
HDA036 spec states:
DP (Display Port) indicates whether the Pin Complex Widget supports
connection to a Display Port sink. Supported if set to 1. Note that
it is possible for the pin widget to support more than one digital
display connection type, e.g. HDMI and DP bit are both set to 1.
Also export the DP pin cap in procfs.
- ALSA: hda - show HBR(High Bit Rate) pin cap in procfs
Note that the HBR capability only applies to HDMI pin.
- ALSA: hda - Fix LED GPIO setup for HP laptops with IDT codecs
This patch fixes an error in processing of the HP BIOS configuration to enable
GPIO based mute LED indicator control. That error causes driver to enable
such control on all HP systems with the 92HD75 IDT codecs and results in
unnecessary toggling of the GPIO on mute control manipulation.
It also adds support of the future HP BIOS configuration extension for the
named control. New configuration string has a format HP_Mute_LED_P_G
where P can be 0 or 1 and defines mute LED GPIO control state (low/high)
that corresponds to the NOT muted state of the master volume
and G is the index of the GPIO to use (0..9)
Lastly, it adds more systems to the support of the audio implementation
as found on HP B-series systems

include/linux/netfilter/xt_SECMARK.h which have a struct member called
selctx.
- ALSA: hda - Exclude unusable ADCs for ALC88x
On Realtek codecs, a digital mic pin is connected often only to a single
ADC. But the parser tries to set up all ADCs no matter whether the
digital mic is available, and results in non-selectable input source.
This patch adds a check of input-source availability of each ADC, and
excludes ones that don't support all input sources.

http://article.gmane.org/gmane.linux.alsa.devel/61361/match=
I have been using this patch for a while now
and have to say it works vary well, except for a few minor
things:
With the iMac 24-inch 3.06GHz Intel Core 2 Duo
everything seems to be working as it should,
although I have not looked into the microphone
(never really use one, nor have any apps to test,
my guess is it doesn't work, or I never figured out how
to get it to work).
With the iMac 24-inch 2.66GHz Intel Core 2 Duo
everything is the same as with the above machine
except I'm hearing a light scratchy/distortion noise
come out of the speakers when using headphones(above machine
does not do this).
Other than that the sound level is great(especially with good Dj headphones).

each codec hwdep sysfs directory (e.g. /sys/class/sound/hwC0D0).
The files show the msec length of the codec power-on and power-off,
respectively.

Explanation: The kd_mksound() send SND_BEEP and SND_TONE only to last

- hda_intel: Fix hda_beep.patch according latest alsa-kernel changes
- Fix a typo in hda_intel.patch
Must be #ifdef instead of #if.
- Make MSI white/black-list for HD-audio
Whie the recent kernel works with MSI on non-Intel boards, it doesn't
on older kernels. So, we need to disable MSI as default on such.
- ALSA: hda - simplify usage of HDA_SUBDEV_AMP_FLAG
The HDA_SUBDEV_NID_FLAG is duplicate for amplifier control elements. Move
get_amp_nid_() call to the snd_hda_ctl_add() function.
- ALSA: hda - introduce HDA_SUBDEV_AMP_FLAG (ControlAmp in proc)
The purpose of this changeset is to show information about amplifier
setting in the codec proc file. Something like:
Control: name="Front Playback Volume", index=0, device=0
ControlAmp: chs=3, dir=Out, idx=0, ofs=0
Control: name="Front Playback Switch", index=0, device=0
ControlAmp: chs=3, dir=In, idx=2, ofs=0
- ALSA: hda - add more NID->Control mapping
This set of changes add missing NID values to some static control
elemenents. Also, it handles all "Capture Source" or "Input Source"
controls.
- ALSA: intelhdmi - accept DisplayPort pin
HDA036 spec states:
DP (Display Port) indicates whether the Pin Complex Widget supports
connection to a Display Port sink. Supported if set to 1. Note that
it is possible for the pin widget to support more than one digital
display connection type, e.g. HDMI and DP bit are both set to 1.
Also export the DP pin cap in procfs.
- ALSA: hda - show HBR(High Bit Rate) pin cap in procfs
Note that the HBR capability only applies to HDMI pin.
- ALSA: hda - Fix input and jack Kconfig depenencies
CONFIG_SND_JACK needs to be selected explicitly only when INPUT=y or
INPUT_SND. The current way, INPUT=SND_HDA_INTEL isn't strict enough.
Reported-by: Randy Dunlap <randy.dunlap@oracle.com>
- ALSA: hda - show EPSS capability in proc
- ALSA: hda - introduce snd_hda_jack_detect() and snd_hda_pin_sense()
This helps merge duplicate code.
v2: add snd_hda_jack_detect() and comments recommended by Takashi.
- ALSA: intelhdmi - export monitor-presence and ELD-valid status
- ALSA: hda - Fix build errors with CONFIG_SND_HDA_INPUT_BEEP=n
Disable beep-related codes when CONFIG_SND_HDA_INPUT_BEEP isn't set.
- ALSA: hda - Fix beep_mode option value
The beep_mode option value was wrongly defined: it must be 0 = off and
1 = on.
Also, evaluate the beep_mode value at snd_hda_attach_beep_device()
properly so that no device is created when beep_mode=0 is given.
- ALSA: hda - Get rid of magic digits for subdev hack
Define a proper const for a magic 31bit flag for subdev / NID setup
with a brief comment.
- ALSA: hda - add beep_mode module parameter
The beep_mode parameter for snd-hda-intel module allows to choose among
different digital beep device registation to the input layer.
0 = do not register to the input layer
1 = register to the input layer all time
2 = use "Beep Switch" control exported to user space mixer applications
Also, introduce CONFIG_SND_HDA_INPUT_BEEP_MODE for default value.
- ALSA: hda - proc - add support for dynamic controls to mixer<->NID mapping
This patch adds support for dynamically created controls to proc codec file
(Control: lines).
- ALSA: hda - proc - introduce Control: lines to show mixer<->NID assignment
This is an initial patch to show universal control<->NID assigment in
proc codec file. The change helps to debug codec related problems.
- ALSA: hda - move snd_hda_pcm_type_name from hda_codec.h to hda_local.h
The snd_hda_pcm_type_name array is local only.
- ALSA: hda - Don't access invalid substream in proc file
The commit e3303235209c0496b490e10ab131e72a9568c153
"ALSA: hda - proc - show which I/O NID is associated to PCM device"
introduces the access to substream pointer. But, PCMs may have no
substreams in one or both directions, and this results in NULL
dereference. Also, print the first substream number doesn't make
sense.
This patch removes the access to the substream pointer, and reformat
to fit to the standard coding style.
- ALSA: hda - Fix build error without CONFIG_SND_HDA_HWDEP=y
CONFIG_SND_HDA_POWER_SAVE is independent from CONFIG_SND_HDA_HWDEP.
Thus snd_hda_hwdep_add_power_sysfs() needs the check of both kconfigs.
- ALSA: hda - Add power on/off counter
Added the power on/off counter and expose via sysfs files.
The sysfs files, power_on_acct and power_off_acct, are created under
each codec hwdep sysfs directory (e.g. /sys/class/sound/hwC0D0).
The files show the msec length of the codec power-on and power-off,
respectively.
- ALSA: hda - proc - show which I/O NID is associated to PCM device
Output something like:
Node 0x02 [Audio Output] wcaps 0x11: Stereo
Device: name="ALC888 Analog", type="Audio", device=0, substream=0
Converter: stream=0, channel=0
...
- [ALSA] hda: beep - add missing cancel_delayed_work
The unregister work should be also canceled in snd_hda_detach_beep_device()
function.
- ALSA: hda - vectorize intelhdmi
The Intel IbexPeak HDMI codec supports 2 converters and 3 pins,
which requires converting the cvt_nid/pin_nid to arrays.
The active pin number (the one connected with a live HDMI monitor/sink)
will be dynamically identified on hotplug events.
It exports two HDMI devices, so that user space can choose the A/V pipe
for sending the audio samples.
It's still undefined behavior when there are two active monitors
connected and routed to the same audio converter.
- [ALSA] hda_intel: Digital PC Beep - delay input device unregistration
The massive register/unregister calls for input device layer might be
overkill. Delay unregister call by one HZ as workaround.
Also, as benefit, beep->enabled variable is changed immediately now
(not from workqueue).
- hda_intel: Digital PC Beep - change behaviour for input layer
Original implementation was keeping registered input device for SND_BEEP
and SND_TONE events all time. This patch changes this behaviour:
If digital PC Beep is turned off using universal control switch,
the input device is unregistered.
Explanation: The kd_mksound() send SND_BEEP and SND_TONE only to last
registered device acceping those events. It means that the HDA Intel
audio driver blocks also the internal PC Speaker device (pcspkr.c
driver) even if the HDA Beep is muted. The user can easy disable
all beeps using 'setterm -blength 0' or 'xset b off' command.

HR timer driver

- Refresh patches to remove fuzz
- ALSA: hrtimer - Fix lock-up
The timer stop callback can be called from snd_timer_interrupt(), which
is called from the hrtimer callback. Since hrtimer_cancel() waits for
the callback completion, this eventually results in a lock-up.
This patch fixes the problem by just toggling a flag at stop callback
and call hrtimer_cancel() later.

I2C cs8427

- Add a workaround for bitrev8() in i2c/cs8427.c
- ALSA: ice1712: Use bitrev8

ICE1712 driver

- Add a build stub for pci/ice1712/quartet.c
- ALSA: ice1724 - aureon - modify WM8770 Master & DAC volume
The volume levels in original implementation are incorrect and does
not match the dB scale. The real range is linear (in the sense of
the dB scale) from 0dB to -100dB. Remove logaritmic table and make
all volumes from range 0dB..100dB.
The tests are in RedHat's bugzilla #540817.
- tree-wide: fix a very frequent spelling mistake
something-bility is spelled as something-blity
so a grep for 'blit' would find these lines
this is so trivial that I didn't split it by subsystem / copy
additional maintainers - all changes are to comments
The only purpose is to get fewer false positives when grepping
around the kernel sources.
- ALSA: ice1724 - make some bitfields unsigned
This is a clean up and doesn't change the behavior.
Bit fields should always be unsigned. Otherwise pm_suspend_enabled will
be -1 when you want it to be 1. The other bad thing is that the sparse
checker will complain 36 times if they aren't unsigned.
The other bitfields in that struct are unsigned already.
- ALSA: ice1724 - Fix section mismatch in prodigy_hd2_resume()
Remove invlid __devinit prefix from the suspend callback.
- ALSA: ice1724 - Patch for suspend/resume for ESI Juli@
Add proper suspend/resume code for Juli@ cards. Based on ice1724
suspend/resume work of Igor Chernyshev.

* codec regs listed in proc for all codecs/chips
* adding total regs for each codec
* fixing nb. of steps in input attenuation controls
- ALSA: ICE1712/24 - Change the Multi Track Peak control (level meters) from MIXER to PCM type
* PLEASE NOTE - this change requires the corresponding update of
envy24control for ice1712 - kind of an ABI change.
* The "Multi Track Peak" control is read-only level meters indicator.
* The control is VERY confusing to most users since it is currently displayed
in regular mixers. E.g. alsamixer ignores its read-only status
and allows changing the levels with keys which makes no sense.

ICE1724 driver

- ALSA: ice1724 - Infrasonic Quartet support
* three external clock types
* all controls supported
- ALSA: ice1724 - Support for multiple external clock types
* Support for customization of the external clock names
* Adding hooks to playback_pro_open and capture_pro_open, allowing e.g.

* required rate and current rate are compared for internal clock mode only
- ALSA: ice1724 - adding GPIO routines for mask and direction
* get/set routines for GPIO mask and direction
- ALSA: ice1724 - Make call to set hw params succeed on ESI Juli@
If two streams are started immediately after one another (such as a
playback and a recording stream), the call to set hw params fails with
EBUSY. This patch makes the call succeed, so playback and recording will
work properly.
- ALSA: ice1724: Fix surround on Chaintech AV-710
Fix the num_total_dacs setting for Chaintech AV710. The existing comment
that only PSDOUT0 is connected is correct, but since the card is using
packed AC97 mode to send 6 channels to the codec, num_total_dacs should be
set to 6 and not 2. This allows 6-channel surround to work. Also clarify
a comment regarding the additional WM8728 codec on this card (it's connected
to the SPDIF output and always receives the same data).
- ALSA: ice1724: increase SPDIF and independent stereo buffer sizes
Increase the default and maximum PCM buffer prellocation size for ice1724's
SPDIF and independent stereo pair outputs to 256K, which is the hardware's
maximum supported size. This allows a reduction in interrupt rate and
potentially power usage when an application is not latency-critical.
- ALSA: ICE1712/24 - Change the Multi Track Peak control (level meters) from MIXER to PCM type
* PLEASE NOTE - this change requires the corresponding update of
envy24control for ice1712 - kind of an ABI change.

ISA

- ALSA: dt019x: merge into the als100 driver
The als100 driver is so similar to the dt019x/als007 driver
that one driver's source can be used for both drivers with
only few changes. Merge the dt019x driver into the als100.
- ALSA: sscape: convert to firmware loader framework
The conversion solves the problem that firmware size was set to 64KB
while non PnP cards have 128KB firmware files.
An additional firmware initialization code has been moved from the OSS
driver.
- ALSA: sscape: add supoort for SPEA Media FX/Reveal SC-600
Move code from the OSS sscape driver in order to support old Soundscape OEM models.

ISA DMA

- ALSA: snd_dma_pointer workaround for chipsets with buggy DMA
The chipsets with the isa_dma_bridge_buggy set do not stop DMA during
DMA counter reads. The DMA counter is read in two 8-bit read steps
on x86 platform. Sometimes, such reads happen during higher byte
change so the lower byte is already decremented (rolled over) but
the higher byte is not. It introduces an error that position is
moved 256 bytes ahead of the true position. Thus, the next DMA
position read can return a lower value then the previous read.
If the DMA position is decreased (reversed) the ALSA subsystem is
tricked into the playback underrun error and resets the playback.
It results in a "pop" during a playback.
Work around the issue by reading the counter twice and choosing a higher
value.

Intel8x0 driver

- ALSA: intel8x0: Mute External Amplifier by default for Gateway 4525GZ

- ALSA: intel8x0 - Mute External Amplifier by default for Sony VAIO VGN-B1VP
BugLink: https://bugs.launchpad.net/bugs/410933
This Sony VAIO model also needs External Amplifier unmuted for audible

LX6464ES

- ALSA: lx6464es - remove unused struct member
we cannot set the sampling rate of the device, but can only read it
from the board, so we don't need the member for it.
- ALSA: lx6464es - cleanup of rmh message bus function
the rmh bus is not used asynchronously, so it is safe to remove the
specific code pieces.

OSS device core

- Driver-Core: extend devnode callbacks to provide permissions
This allows subsytems to provide devtmpfs with non-default permissions
for the device node. Instead of the default mode of 0600, null, zero,
random, urandom, full, tty, ptmx now have a mode of 0666, which allows
non-privileged processes to access standard device nodes in case no
other userspace process applies the expected permissions.
This also fixes a wrong assignment in pktcdvd and a checkpatch.pl complain.

Opti9xx drivers

- ALSA: opti93x: use dB scale for mixer controls
Add dB scale for mixer controls. Fix dB scale for
Master Volume control.
- ALSA: opti93x: move controls definitions to opti93x driver
Move OPTi93x controls definitions to the opti93x driver
from the common wss-lib library module. These controls
are used only by the opti93x driver.
Also, fix capture source names. They are the same as
opl3sa2 names.
- tree-wide: fix assorted typos all over the place
That is "success", "unknown", "through", "performance", "[re|un]mapping"
, "access", "default", "reasonable", "[con]currently", "temperature"
, "channel", "[un]used", "application", "example","hierarchy", "therefore"
, "[over|under]flow", "contiguous", "threshold", "enough" and others.
- ALSA: opti93x: fix irq releasing if the irq cannot be allocated
Use the chip->irq to check if the irq should be released so the irq is not released
if it has not been allocated.
- ALSA: opti93x: set MC indirect registers base from PnP data
The PnP data on the OPTI931 and OPTI933 contains io port
range for the MC indirect registers. Use the PnP range
instead of hardwired value 0xE0E.
Also, request region of MC indirect registers so it is
marked as used to other drivers (this was missing previously).
- ALSA: opti9xx: remove snd_opti9xx fields
Remove snd_opti9xx fields which are indirect arguments to
the snd_opti9xx_configure(). Pass these values as function
arguments.
- ALSA: opti-miro: add PnP detection
The PCM12 and PCM20 can be set into the ISA PnP mode. The PCM12 PnP
was sold as the PnP device.
Add code to handle detection of these cards using ISA PnP framework.
Tested on the PCM20 in PnP mode. The PCM12 PnP has the same MS Windows
INF file except for a card name displayed for user.
- ALSA: opti-miro: separate comon probing code
Separate common probing code in order to use it
for PnP probing.
- ALSA: opti-miro: fix OOPS if hardware is not detected
If a hardware is not detected there is a kernel crash
due to not initialized snd_miro->aci pointer. This pointer
is initialized after detection of the opti (miro) chip.
This bug was introduced by patches to expose
ACI mikser outside the snd-miro driver.
- ALSA: opti-miro: expose ACI mixer to outside drivers
The ACI mixer is used to control the radio FM module
installed on the Miro PCM20 sound card. Expose ACI mixer
outside the sound card driver.
- ALSA: opti-miro: make miro.h header available outside the alsa directory
Move the miro.h header to the include/sound directory. It can
be used in the Miro PCM20 radio driver (v4l).
- ALSA: opti-miro: remove snd_card pointer from snd_miro structure
Remove the snd_card pointer from the snd_miro structure and
do some small code improvements.
Also, move Opti chipset detection before detection of the
ACI mixer, so the mci_base value is set in one place only.
- ALSA: opti-miro: Fix missing semicolon
To fix a build error
sound/isa/opti9xx/miro.c:1281: error: expected ';' before '}' token
- ALSA: opti-miro: use variables directly in the probe function
Use the fm_port and mpu_port variables directly in a probe function.
This completely eliminates a need to copy the fm_port value to
the snd_miro structure.

PARISC Harmony driver

- ALSA: sound/parisc: Move dereference after NULL test
If the NULL test on h is needed in snd_harmony_mixer_init, then the
dereference should be after the NULL test.
Actually, there is a sequence of calls: snd_harmony_create, then
snd_harmony_pcm_init, and then snd_harmony_mixer_init. snd_harmony_create
initializes h, but may indeed leave it as NULL. There was no NULL test at
the beginning of snd_harmony_pcm_init, so I have added one. The NULL test
in snd_harmony_mixer_init is then not necessary, but in case the ordering
of the calls changes, I have left it, and moved the dereference after it.
A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@match exists@
expression x, E;
identifier fld;
@@

PDAudioCF driver

- pcmcia: rework the irq_req_t typedef
Most of the irq_req_t typedef'd struct can be re-worked quite
easily:
(1) IRQInfo2 was unused in any case, so drop it.
(2) IRQInfo1 was used write-only, so drop it.
(3) Instance (private data to be passed to the IRQ handler):
Most PCMCIA drivers using pcmcia_request_irq() to actually
register an IRQ handler set the "dev_id" to the same pointer
as the "priv" pointer in struct pcmcia_device. Modify the two
exceptions (ipwireless, ibmtr_cs) to also work this waym and
set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
(4) Handler is to be of type irq_handler_t.
(5) Handler != NULL already tells whether an IRQ handler is present.
Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
irq_req_t.Attributes.

Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)

This is a port of the sound/oss/sh_dac_audio.c driver.
The driver uses an on-chip 8-bit D/A converter, which has a speaker connected

For interrupts it uses a high-resolution timer (hrtimer).
Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx).
Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver
would be obsolete soon, and it could be removed.

- ASoC: Codec driver for Texas Instruments tlv320dac33 codec
Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo
audio DAC.
TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low
power audio playback.
The digital interface can use I2S, DSP (A or B), Right and Left
justified formats.
DAC33 has stereo analog input, which can be bypassed to the analog
outputs.
Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass'
mode (default) and nSample mode (FIFO is in use).
a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is
working synchronously as a normal codec (it needs constant stream of
data on the digital interface).
b) The nSample mode implementation uses one interrupt line from DAC33 to
the host:
Alarm threshold is set to 10ms of audio data (limit by the driver
implementation).
DAC33 will signal an interrupt, when the FIFO level goes under the
Alarm threshold.
The host will write to nSample register a value (number of stereo
samples), to tell DAC33 how many samples it should read in a burst from
the host. When the DAC33 received the number of samples, it disables the
clocks on the I2S bus. When the FIFO use again goes under the Alarm
threshold, DAC33 signals the host with an interrupt, and the process is
repeated.

SoC Codec TPA6130A2

- ASoC: Minor fixups to tpa6130a2 driver
- Staticise ttpa6130a2_client.
- Remove unneeded cast from void.
- Use explict NULL rather than 0.
- ASoC: TPA6130A2 amplifier driver
Driver for Texas Instruments TPA6130A2 stereo headphone
amplifier.
The driver provides playback gain control and also pre-defined
DAPM_HP widgets and DAPM routings for power management.
The DAPM_HP widget names are:
"TPA6130A2 Headphone Left"
"TPA6130A2 Headphone Right"
From soc machine drivers to use with the tpa6130a2 amplifier,
the tpa6130a2_add_controls has to be called, which adds the alsa
controls and the DAPM routing needed for the tpa6130a2.
After that the machine driver can connect the codec's output
with 'TPA6130A2 Left' and 'TPA6130A2 Right':
{"TPA6130A2 Left", NULL, "CODEC LEFT OUT"},
{"TPA6130A2 Right", NULL, "CODEC RIGHT OUT"},
Internally the left and right channels are powered separately.
When none of the channels are needed the amplifier is powered
down:
hard power: valid GPIO number is passed within platform data
soft power: Using the software shutdown of the amplifier

SoC Codec TWL4030

- ASoC: TWL4030: Add APLL supply for the capture path
Capture path also need the APLL enabled, adding DAPM_SUPPLY

- ASoC: TWL4030: Change APLL powering sequence
It seams that certain part of the twl4030 codec needs the APLL
enabled before they are enabled.
Paths which has any digital processing needs need the APLL
enabled before they can function.
For example the vibra output will have some random data after
it is enabled and before the APLL also enabled.
If only analog components are in use (analog bypass), than it
seams, that the APLL does not need to be enabled. This lowers
the power consumption with around ~0.005A.
Adding DAPM_SUPPLY to the Digital playback route and also
to the capture route to enable and disable the APLL.
- ASoC: TWL4030: Vibra motor stop fix when it is driven with audio
This patch fixes vibrator playing incoherently, when driven

H-bridge and VIBRA_SET still affects PWM generator.
Slowest value fixes things.
- ASoC: TWL4030: Change codec_muted to apll_enabled
codec_muted is missleading, change it to apll_enabled,
which is what it is doing: enabing and disabling the APLL.
- ASoC: TWL4030: Remove bypass tracking
Since ASoC core now handling the codec bias differently
there is no need to do the tracking of bypass switch states
anymore.
Handling of the common bit for analog loopbacks is done with
DAPM_SUPPLY for the bypass paths.
Now this bit is only enabled when there is a complete analog
bypass path, compared to the previous implementation, when the
global switch was enabled if there were any of the analog
bypass switch was on (regardless if there were complete path or
not)

- ASoC: DaVinci: McASP FIFO related updates
The DMA params for McASP with FIFO has been updated so that it works for

params data structure. The fifo_level can be adjusted by the tx[rx]_numevt

- ASoC: Davinci: Add audio codec support for DM365 EVM
This patch enables tlv320aic3101 support on DM365 EVM and
it was tested on DM365 EVM rev c.
Note: this patch was created based on temp/asoc branch.
- ASoC: DaVinci: Correct McASP FIFO initialization
McASP write FIFO registers should be modified for playback and read FIFO
registers for capture. Check the PCM mode before manipulating the
FIFO registers. Currently, irrespective of playback/capture both the
FIFOs are enabled or disbaled. This resulted in errors in audio loopback
mode.
- ASoC: Davinci: Fix race with cpu_dai->dma_data
This patch removes references to cpu_dai->dma_data.

It removes the unused name variable from davinci_pcm_dma_params.
- ASoC: DaVinci: Fix divide by zero error during 1st execution

in davici_pcm_open. This patch also makes the race smaller
but the next patch provides a better fix.
- ASoC: DaVinci: Fixes to McASP configuration

- Move queue related mappings to dm<soc>.c
EDMA in DM355 and DM644x has two transfer controllers while DM646x
has four transfer controllers. Moving the queue to tc mapping and
queue priority mapping to dm<soc>.c will be helpful to probe these
mappings from platform device so that the machine_is_* testing will
be avoided.
- add channel mapping logic
Channel mapping logic is introduced in dm646x EDMA. This implies
that there is no fixed association for a channel number to a
parameter entry number. In other words, using the DMA channel
mapping registers (DCHMAPn), a PaRAM entry can be mapped to any
channel. While in the case of dm644x and dm355 there is a fixed
mapping between the EDMA channel and Param entry number.

SoC Dynamic Audio Power Management

- ASoC: Fix suspend with active audio streams
When we get a stream suspend event force the power down since otherwise
the stream would remain marked as active. In future we'll probably want
to make this stream-specific and add an interface to make the power down
of other widgets optional in order to support leaving bypass paths
active while suspending the processor.

- ASoC: Serialize access to dapm_power_widgets()
Access to damp_power_widgets() is assumed to be single-threaded.
Concurrent accesses to dapm_power_widgets() may result in
unpredictable behavior.
Calls from:
close_delayed_work()
soc_codec_close()
soc_pcm_prepare()
soc_suspend()
soc_resume_deferred()
to snd_soc_dapm_stream_event() do not have the codec->mutex
taken to cover the call to dapm_power_widgets(). Thus, take
the mutex in these paths also to assure single-threaded use
of dapm_power_widgets().
- ASoC: Add virtual enumeration support for DAPM muxes
Sometimes it is desirable to have a mux which does not reflect any
direct register configuration but which will instead only have an
effect implicitly (for example, as a result of changing which parts
of the device are powered up). Provide a virtual mux for this purpose.
- ASoC: Push DAPM enumeration register change test out
Don't assume that enumerations are backed by registers when updating
mux power.
- ASoC: Simplify code for DAPM widget updates
We don't need to check for an event callback since we also check for
an appropriate event flag when applying mux status changes.
- ASoC: Allow per-route connectedness checks for supplies
Some chips with complex internal supply (particularly clocking)
arragements may have multiple options for some of the supply
connections. Since these don't affect user-visible audio routing
the expectation would be that they would be managed automatically
by one of the drivers.
Support these users by allowing routes to have a connected function
which is queried before the connectedness of the path is checked as
normal. Currently this is only done for supplies, other widgets
could be supported but are not currently since the expectation for
them is that audio routing will be under the control of userspace.
- ASoC: Fix SND_SOC_DAPM_LINE handling
Since the SND_SOC_DAPM_LINE can be input or output, additional check is
needed in order to determine if the widget is connected as input or
output.
When checking for connected outputs, if the widget is line, than check
if the sources list is not empty (line is connected as output)
For input endpoint check, when the widget is line, also check if the
sinks list is not empty (line is connected as input).

- ASoC: move setting ac97 platformdata earlier than ac97 read/write
While probing, AC97 codec drivers and soc-core generically execute the
following sequence:
snd_soc_new_ac97_codec -> snd_soc_new_pcms -> reset ac-link/read AC97 ID
to detect ->... -> set platform_data to ac97 by soc-core
commit 474828a40f6ddab6e2a3475a19c5c84aa3ec7d60 adds platform_data to
snd_ac97 instance. But ac97 platform data hasn't given to snd_ac97
before actual ac97 operations. Then while ac97_read access platform_data
of snd_ac97 for detecting, NULL pointer oops will fire. That means old
platform_data patch doesn't work in real-life cases.
This patch moves the operation of setting ac97 platform_data earlier
than ac97 reading/writing operations. Then it makes platform_data of
AC97 become practically useful.

make sure the codec mutex is taken from the driver.
- ASoC: remove io_mutex
Remove the io_mutex. It has a drawback of serializing
all accesses to snd_soc_update_bits() even when multiple
codecs are in use. In addition, it fails to actually do
its task - during snd_soc_update_bits(), dapm_update_bits()

- ASoC: Codec driver for Texas Instruments tlv320dac33 codec
Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo
audio DAC.
TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low
power audio playback.
The digital interface can use I2S, DSP (A or B), Right and Left
justified formats.
DAC33 has stereo analog input, which can be bypassed to the analog
outputs.
Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass'
mode (default) and nSample mode (FIFO is in use).
a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is
working synchronously as a normal codec (it needs constant stream of
data on the digital interface).
b) The nSample mode implementation uses one interrupt line from DAC33 to
the host:
Alarm threshold is set to 10ms of audio data (limit by the driver
implementation).
DAC33 will signal an interrupt, when the FIFO level goes under the
Alarm threshold.
The host will write to nSample register a value (number of stereo
samples), to tell DAC33 how many samples it should read in a burst from
the host. When the DAC33 received the number of samples, it disables the
clocks on the I2S bus. When the FIFO use again goes under the Alarm
threshold, DAC33 signals the host with an interrupt, and the process is
repeated.
- ASoC: Remove snd_soc_suspend_device()

- ASoC: Add SPI support to WM8711
- ASoC: TPA6130A2 amplifier driver
Driver for Texas Instruments TPA6130A2 stereo headphone
amplifier.
The driver provides playback gain control and also pre-defined
DAPM_HP widgets and DAPM routings for power management.
The DAPM_HP widget names are:
"TPA6130A2 Headphone Left"
"TPA6130A2 Headphone Right"
From soc machine drivers to use with the tpa6130a2 amplifier,
the tpa6130a2_add_controls has to be called, which adds the alsa
controls and the DAPM routing needed for the tpa6130a2.
After that the machine driver can connect the codec's output
with 'TPA6130A2 Left' and 'TPA6130A2 Right':
{"TPA6130A2 Left", NULL, "CODEC LEFT OUT"},
{"TPA6130A2 Right", NULL, "CODEC RIGHT OUT"},
Internally the left and right channels are powered separately.
When none of the channels are needed the amplifier is powered
down:
hard power: valid GPIO number is passed within platform data
soft power: Using the software shutdown of the amplifier
- ASoC: Improve the debugfs hierarchy
Change the way the debugfs entries are created:
If the codec->dev is valid, than use:
debugfs/asoc/{codec->name}.{dev_name(codec->dev)}/
if the codec->dev is NULL:
debugfs/asoc/{codec->name}/
as root for the debugfs entries.
- ASoC: add support for multiple cards/codecs in debugfs
In order to support multiple codecs on the same system in the debugfs
the directory hierarchy need to be changed by adding directory per codec
under the asoc direcorty:
debugfs/asoc/{dev_name(socdev->dev)}-{codec->name}/codec_reg
/dapm_pop_time
/dapm/{widgets}
With the original implementation only the debugfs files are only
created for the first codec, other codecs loaded later would fail to
create the debugfs files (since they are already exist).
Furthermore in this situation any of the codecs has been removed, would
cause the debugfs entries to disappear, regardless if the codec, which
created them are still loaded (the one which loaded first).

- ASoC: OMAP: Don't try to set unsupported OMAP_DMA_DATA_BURST_16 on OMAP1
After DMA burst mode has been introduced in sound/soc/omap/omap-pcm.c,
omap_pcm_prepare() unconditionally calls:
omap_set_dma_src_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);
omap_set_dma_dest_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16);
Current implementation of those two functions found in
arch/arm/plat-ompa/dma.c doesn't support OMAP_DMA_DATA_BURST_16 on OMAP1 at
all, so they both end with BUG() on that machine. That results in
ASoC being completely unusable, at least on my OMAP5910 based Amstrad Delta.
The patch corrects the problem by not calling those two functions when run on
OMAP1 class based machines.
Created against linux-2.6.32-rc5.
Tested on Amstrad Delta.

- ASoC: Amstrad Delta minor cleanups
Hi Mark,
Here is a patch that corrects small omissions I have found in my code.
- ASoC: Amstrad Delta: add info about the line discipline requirement to Kconfig help text
I thought it could be usefull to add some information on how to get the device
fully supported by loading a line discipline on the modem line.
- ASoC: OMAP: Add functionality to set CLKR and FSR sources in McBSP DAI
The McBSP1 port in OMAP3 processors (I believe OMAP2 too but I don't have
specifications to check it) have additional CLKR and FSR pins for McBSP1
receiver. Reset default is that receiver is using bit clock and frame
sync signal from those pins but it is possible to configure to use
also CLKX and FSX pins as well. In fact, other McBSP ports are doing that
internally that transmitter and receiver share the CLKX and FSX.
Add functionaly that machine drivers can set the CLKR and FSR sources by
using the snd_soc_dai_set_sysclk.
Thanks to "Aggarwal, Anuj" <anuj.aggarwal@ti.com> for reporting the issue.

Sound Scape driver

- ALSA: sscape: coding style fixes
Fix coding style errors in the driver.
Also, add missing argument for CMD_XXX_MIDI_VOL command.
- ALSA: sscape - Remove invalid __devinitdata to module parameters
Module parameters shouldn't be marked as __devinitdata since they can be
referred via sysfs even after probing.
- ALSA: sscape: force AD1848 codec mode on old Soundscape
Old Soundscape cards (pre PnP) work only with AD1848 codecs.
If the CS4231 codec is installed it must be used in AD1848
compatible mode.
Also, add gameport support and remove an unused mpu field.
- ALSA: sscape: remove MIDI instances counting with limit ULONG_MAX
There is no sense to limit open MIDI connections with limit
as high as ULONG_MAX.
Also, convert more messages to use the snd_printk.
Correct few old and misleading comments as well.
- ALSA: sscape: convert to firmware loader framework
The conversion solves the problem that firmware size was set to 64KB
while non PnP cards have 128KB firmware files.
An additional firmware initialization code has been moved from the OSS
driver.
- ALSA: sscape: add supoort for SPEA Media FX/Reveal SC-600
Move code from the OSS sscape driver in order to support old Soundscape OEM models.

SuperH DAC audio driver

- ALSA: sh: add SuperH DAC audio driver for ALSA V4
This is a port of the sound/oss/sh_dac_audio.c driver.
The driver uses an on-chip 8-bit D/A converter, which has a speaker connected
to one of its channels, found in several ancient HP machines.
For interrupts it uses a high-resolution timer (hrtimer).
Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx).
Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver
would be obsolete soon, and it could be removed.

- Fix a missing patch chunk in usx2yhwdeppcm.patch
- Refresh vm_ops related patches
The patches got broken due to the upstream changes of vm_ops to the

- ALSA: snd-usb-us122l: add product IDs of US-122MKII and US-144MKII
I added the product IDs of the new revisions of the devices, so owners
can test whether this suffices to make them work. Patched against ALSA
snapshot 20091207.
- sound: usxxx: cleanup chip field
The chip field is no longer needed. Move those of its fields that are
actually used to the device structure itself.
- sound: usb: make the USB MIDI module more independent
Remove the dependecy from the USB MIDI code on the snd_usb_audio

- ALSA: snd-usb-us122l: corrent error number for not probing US-144 on ehci-hcd
snd-usb-us122l: corrent error number for not probing US-144 on ehci-hcd

Adds support for US-144 when attached on USB1.1.
Unlike the US-122L it uses both USB interfaces 0 and 1.

- ALSA: usb - Quirk to disable master volume control in PCM2702
Disable the master volume control in the PCM2702 chipset.
The datasheet documents two independent channel volume controls, one
master mute control and one master volume control. All controls are
fully functional except for the master volume control, which returns
USB stalls on all GET requests.
- sound: usb: make the USB MIDI module more independent
Remove the dependecy from the USB MIDI code on the snd_usb_audio
structure. This allows using the USB MIDI module from another driver
without having to pretend to be the generic USB audio driver.
- ALSA: usb-audio: fix combine_word problem
Fix combine_word problem where first octet is not
read properly. The only affected place seems to be the
INPUT_TERMINAL type. Before now, sound controls can be created
with the output terminal's name which is a fallback mechanism
used only for unknown input terminal types. For example,
Line can wrongly appear as Speaker. After the change it
should appear as Line.
The side effect of this change can be that users
can expect the wrong control name in their scripts or
programs while now we return the correct one.
Probably, these defines should use get_unaligned_le16 and
friends.

VIA82xx driver

- sound: via82xx: deactivate DXS controls of inactive streams
Activate the DXS volume controls only when the corresponding stream is
being used. This makes the behaviour consistent with the other drivers
that have per-stream volume controls.
- sound: via82xx: move DXS volume controls to PCM interface
The "VIA DXS" controls are actually volume controls that apply to the
four PCM substreams, so we better indicate this connection by moving the
controls to the PCM interface.
Commit b452e08e73c0e3dbb0be82130217be4b7084299e in 2.6.30 broke the
restoring of these volumes by "alsactl restore" that most distributions
use; the renaming in this patch cures that regression by preventing
alsactl from applying the old, wrong volume levels to the new controls.

WSS library

- ALSA: opti93x: move controls definitions to opti93x driver
Move OPTi93x controls definitions to the opti93x driver
from the common wss-lib library module. These controls
are used only by the opti93x driver.
Also, fix capture source names. They are the same as
opl3sa2 names.
- ALSA: cs4236: update control names
Update control names to be more closer to their meaning.
Change the "Mono" name to the "Beep" as this line is usually
used to forward the PC beeper signal to sound card's output.
Update names for both cs423x and wss.
Clean up cs4235 controls according to the cs4235 doc. Rename
some of the cs4235 controls to be consistent with the cs4236's
ones.
Also, delete one misnamed cs4231 register define.
- ALSA: cs4236: detect chip in one pass
The cs4236 was two step detection with call to the snd_wss_free()
between two steps. The snd_wss_free() did not free a sound device
created in the snd_wss_create(). This caused an OOPS during module
removal as the same sound device was released twice. The same OOPS
happened if the cs4236 module loading failed.
Fix this by adapting the snd_cs4236_create() to correctly work with
chips less capable then cs4236. The snd_cs4236_create() behaves the
same as the snd_wss_create() if the chip is less capable than the cs4236.
- ALSA: wss: reuse CS4231 controls for AD1848
The C4231 control set is a superset of the AD1848 control
set so reuse the CS4231 controls definitions for the AD1848.
- ALSA: wss: convert CS4231 mixer to dB scale
Convert CS4231 mixer to dB scale after AD1848 mixer.
Also, add missing microphone boost control for the AD1848
and correct wrong bits for loopback volume on the AD1848.

- Open device nodes with close-on-exec flag
- configure.in: Add m4 check for new AM_SILENT_RULES
Kbuild like output for automake (>=1.11). It's no hard dependency as it needs
the newest automake, but enable it by default if it is available. To turn it off
you can either use --disable-silent-rules at configure time or make V=0 at
compile time.
- cvscompile: Remove in favour of gitcompile.
Alsa-lib is no longer hosted in cvs but in git and the only difference between
both helper scripts is the name of the NO_MAKE env VAR check.
- Release v1.0.21a

Control API

- Remove redefinition of _GNU_SOURCE and __USE_GNU
Now _GNU_SOURCE is already defined globally in configure.in.
- Remove old commented-out FD_CLOEXEC code
- namehint: list card independent devices only once
Card-independent devices such as "null" or "pulse" should only be
added once, not once for each card.
- namehint: Allow snd_device_name_hint to search for CTL devices.
- namehint: add missing list->card initialization
list->card is wrongly assumed to be initialized, but the previous
initialization is within a conditional that is false when only
card-independent devices are found. (This is the case when searching
for mixers on my system; the end result is that the "pulse" mixer is
listed three times.)
- Fix corruption after snd_device_name_hint()
snd_device_name_hint() corrupts the config name space after its call.
This results in the error from the suceeding calls of snd_pcm_open()
after snd_device_name_hint().
The bug is in try_config() in namehint.c; it calls snd_config_delete(res)
but res can be two different objects in the function. One is the object
obtained via snd_config_search_definition(), and another is the one from
snd_config_search_alias_hooks(). The former is the expanded objects,
thus it should be freed. But, the latter is a reference, and must not be
freed.
This patch adds the check to free or not.

Mixer API

- mixer: fix enum check
The recent CHECK_ENUM fix uncovered a bug in snd_mixer_selem_is_enumerated()
which would now return -EINVAL for any non-enum control, which would be
interpreted as 'true' by callers like amixer or alsamixer.
- simple_none.c uses HAVE_SOFT_FLOAT it has to include config.h
for this to work properly.
- Fix CHECK_ENUM() in simple.c
simple.c: In function ‘snd_mixer_selem_is_enumerated’:
simple.c:881: warning: suggest parentheses around operand of ‘!’ or change ‘&’ to ‘&&’ or ‘!’ to ‘~’
- mixer: Add Speaker and Beep names to the weight list
Added strings "Speaker" and "Beep" to the weight list so that the entries
appear in more appropriate positions.

PCM API

- Update pcm doc strings
This is information I needed and is based on my understanding of information
from Takashi Iwai.
- Remove old commented-out FD_CLOEXEC code
- pcm_rate_linear: Annotate unused function parameter to avoid compiler warnings.
- dmix - Fix snd_pcm_info()
Call the slave snd_pcm_info() as long as possible in the direct plugins
(i.e. when the PCM device could be opened with O_APPEND mode).
This allows dmix/dsnoop as a salve for PCM hook controls.
- pcm_hw: Always use delay ioctl in snd_pcm_delay()
As the result of snd_pcm_delay() is affected not only by hw_ptr
and appl_ptr, but also by 'runtime->delay' property,
either SNDRV_PCM_IOCTL_DELAY or SNDRV_PCM_IOCTL_STATUS ioctl
must be used to get the correct result.
Previously 'runtime->delay' was ignored in case 'hw->sync_ptr'
was used.
- PCM - Change the hw_params determination order
In snd_pcm_hw_params_choose(), set the buffer size before the period
size and time as default. This will give more useful configuration for
most of apps, i.e. larger buffer size.
For apps that require the old behavior, now the function checks the
environment variable $LIBASOUND_COMPAT. If this variable is set to
non-empty, the hw_params is determined in the old way, first period
then buffer sizes.

Configuration

- Change dmix.conf to accept user configuration from defaults.dmix.<driver_id>.xxx
An attempt to fix problem described in reverted patch "Fix driver conf
parsing in snd_config_hook_load_for_all_cards()".
- Revert "Fix driver conf parsing in snd_config_hook_load_for_all_cards()"
This reverts commit 96da0c842d14b40ce8e37726b259229634b3aa21.
This way of fix brokes card-specific configuration loading.
See http://bugzilla.redhat.com bug#521988 for details.
Appropriate way to handle this problem is to fix the dmix configuration file.

Dynamic Loader helpers

- Remove redefinition of _GNU_SOURCE and __USE_GNU
Now _GNU_SOURCE is already defined globally in configure.in.
- Cache libasound.so access in snd_dlopen
Speed up repeated calls to snd_dlopen by caching the path to
libasound.so; this reduces the instructions executed by
snd_device_name_hint by 40 percent.
