David Henningsson 504333df8b ALSA: usb - Don't trust the channel config if the channel count changed
In case the channel count of the input terminal is not the same as
the channel count of the streaming descriptor, the channel config of
the input terminal can not be trusted. Instead fall back to a default
(guessed) channel map.

This was found on a Logitech USB Headset.

David Henningsson e3e35f750f ALSA: usb - For class 2 devices, use channel map from altsettings
The channel config from the streaming descriptor is probably a
better indicator of the channel map than the input terminal.
Use the input terminal's channel map as fallback only.

David Henningsson 0dca01c37a ALSA: usb: supply channel maps even when wChannelConfig is unspecified
If wChannelconfig is given for some formats but not others, userspace
might not be able to set the channel map.

This is RFC because I'm not sure what the best behaviour is - to guess
the channel map from the given number of channels (it's quite likely
that one channel is MONO and two channels is FL FR), or just to supply
UNKNOWN for all channels.

But the complete lack of channel map for a format leads userspace to
believe that the format is not available at all. Or am I
misunderstanding how this should be used?

Nicolin Chen 988e8cc41e ASoC: Add pinctrl PM to components of active DAIs
It's quite popular that more drivers are using pinctrl PM, for example:
(Documentation/devicetree/bindings/arm/primecell.txt). Just like what
runtime PM does, it would deactivate and activate pin group depending
on whether it's being used or not.

And this pinctrl PM might be also beneficial to cpu dai drivers because
they might have actual pinctrl so as to sleep their pins and wake them
up as needed.

To achieve this goal, this patch sets pins to the default state during
resume or startup; While during suspend and shutdown, it would set pins
to the sleep state.

As pinctrl PM would return zero if there is no such pinctrl sleep state
settings, this patch would not break current ASoC subsystem directly.

[ However, there is still an exception that the patch can not handle,
that is, when cpu dai driver does not have pinctrl property but another
device has it. (The AUDMUX <-> SSI on Freescale i.MX6 series for example.
SSI as a cpu dai doesn't contain pinctrl property while AUDMUX, an Audio
Multiplexer, has it). In this case, this kind of cpu dai driver needs to
find a way to obtain the pinctrl property as its own, by moving property
from AUDMUX to SSI, or creating a pins link/dependency between these two
devices, or using a more decent way after we figure it out. ]

Anssi Hannula 611885bc96 ALSA: hda - hdmi: Disallow unsupported 2ch remapping on NVIDIA codecs
NVIDIA HDMI codecs do not seem to follow the Audio Sample Packet (ASP)
channel mapping (as set by verb F32h per HDA specification 7.3.3.41)
when playing back 2-channel audio (CEA CA 0x00).

Basically this means that specifying swapped channels for stereo audio
(FR,FL) does not take effect, and e.g. this command plays back on the
wrong channel:
speaker-test -c2 -Dhdmi:CARD=NVidia,DEV=0 -m FR,FL -s1

Multichannel audio is not affected.

This issue has been confirmed to exist on codec 0x10de0015 by me and on
0x10de0040 by Juho Teperi.

Disable 2ch FL/FR channel swapping on all NVIDIA HDMI codecs that use
the standard HDA channel mapping system. Since this is a very minor
functionality loss, we err on the side of disabling it for newer codecs
as well until any future testing confirms that this issue has been
fixed.

For Valleyview display codec, if an unused pin chooses an assgined converter
selected by a used pin, playback on the unused pin can also give sound to the
output device of the used pin. It's because data flows from the same convertor
to the display port of the used pin. This issue is same as Haswell.

So this patch avoids using assinged convertors for unused pins.

This is provoked when the ASoC front end is open along with its backend,
(which causes the backend to have a runtime assigned to it) and then the
SNDRV_CTL_IOCTL_PCM_INFO is requested for the (visible) backend device.

Resolve this by ensuring that ASoC internal backend devices are not
visible to userspace, just as the commentry for snd_pcm_new_internal()
says it should be.

Russell King c9bd5e690a DMA-API: sound: fix dma mask handling in a lot of drivers
This code sequence is unsafe in modules:

static u64 mask = DMA_BIT_MASK(something);
...
	if (!dev->dma_mask)
		dev->dma_mask = &mask;

as if a module is reloaded, the mask will be pointing at the original
module's mask address, and this can lead to oopses.  Moreover, they
all follow this with:

	if (!dev->coherent_dma_mask)
		dev->coherent_dma_mask = mask;

where 'mask' is the same value as the statically defined mask, and this
bypasses the architecture's check on whether the DMA mask is possible.

Fix these issues by using the new dma_coerce_coherent_and_mask()
function.

Takashi Iwai 1ac3293095 ALSA: hda - Fix silent headphone on Thinkpads with AD1984A codec
AD1984A codec has a couple of pins with EAPD controls, and the generic
codec driver tries to turn each of them on/off depending on the pin
active state.  However, Thinkpads seem to use EAPD of the speaker pin
as a master EAPD for controlling the mute of all outputs, including
the headphone.  This results in the dead headphone output via the
headphone plugging because it mutes the speaker and turns off EAPD.

The fix is to simply add spec->gen.keep_on_eapd flag.

[This is a regression fix on 3.12 where we moved the AD codec parser
 to the generic parser.  3.11 and earlier didn't show this problem
 because still static quirks have been used.]

Takashi Iwai b63eae0a6c ALSA: hda - Add missing initial vmaster hook at build_controls callback
The generic parser has a support of vmaster hook, but this is
initialized only in the init callback with the check of the presence
of the corresponding kctl.  However, since kctl is NULL at the very
first init callback that is called before build_controls callback, the
vmaster hook sync is skipped there.  Eventually this leads to the
uninitialized state depending on the hook implementation.

This patch adds a simple workaround, just calling the sync function
explicitly at build_controls callback.

Anssi Hannula 7342017f4a ALSA: hda - hdmi: Re-setup pin and infoframe on plug-in on all codecs
hdmi_setup_audio_infoframe() does not set up pin and infoframe if there
is no connected sink. If a sink is connected while audio playback is
already in progress, the pin and infoframe will not be properly set up,
causing no audio or wrongly mapped audio.

On Intel Haswell codecs the hdmi_setup_audio_infoframe() is already
called again from hdmi_present_sense() when an ELD appears because
transcoder:port mapping may have changed.

Make the call non-Haswell-specific so that audio will be properly set up
if the playback was started before a sink was connected.

Tested on non-Haswell Intel HDMI codec by plugging sink in during
playback.

Anssi Hannula 84d69e790f ALSA: hda - hdmi: Disable ramp-up/down for non-PCM on AMD codecs
Recent AMD HDMI codecs (revision ID 3 and later, 0x100300 as reported by
procfs codec#0) have a configurable ramp-up/down functionality.

The documentation ( http://www.x.org/docs/AMD/AMD_HDA_verbs_v2.pdf )
specifies that 180 ("180/256 =~ 0.7") is recommended for PCM and 0 for
non-PCM.

Apply the recommended values according to provided S/PDIF AES0 settings
since ramp-up/down does not make sense for non-PCM.

v2: adapted to hdmi_ops infrastructure

* More note from Anssi:
actually, re-reading mails reveals that Olivier didn't find the
expected difference with this setting, except for "maybe slightly
slower startup with AES0=6" (i.e. value 0, which is unexpected).

So maybe
a) it makes too unnoticiable a difference, or
b) only affects certain hardware (card and/or sink), or
c) ramp-up/down is only triggered with the MUTE bit of
   ATI_VERB_SET_MULTICHANNEL_xx which is also rev3+ specific,
   but is not presently used by the driver,
or something else.

So there's a significant chance setting ramp rate is useless for us ATM,
but probably does not do actual harm either.

Anssi Hannula 5a61358433 ALSA: hda - hdmi: Add ATI/AMD multi-channel audio support
ATI/AMD codecs do not support all the standard HDA HDMI/DP functions,
instead various vendor-specific verbs are provided.

This commit addresses these missing functions:
- standard channel mapping support
- standard infoframe configuration support

ATI/AMD provides their own verbs that allow the following:
- setting CA for infoframe
- setting down-mix information for infoframe
- channel pair remapping
- individual channel remapping (revision ID 3+, 0x100300+)

The documentation for the verbs has now been released by AMD:
http://www.x.org/docs/AMD/AMD_HDA_verbs_v2.pdf

Add support for the ATI/AMD specific verbs and use them instead of the
generic methods on ATI/AMD codecs. This allows multi-channel PCM audio
to work.

Channel remapping is restricted to pairwise mapping on codecs with
revision ID 2 (0x100200 as reported by procfs codec#X) or lower. This
means cards up to Radeon HD7670 as far as I know. This will not affect
standard multi-channel modes since these codecs support automatic
FC-LFE swapping for HDMI.

ATI/AMD codecs do not advertise all of their supported rates, formats
and channel counts, therefore that information is forced accordingly so
that all HDMI 1.x PCM parameters are marked as supported.

Support for multiple ports is also added to patch_atihdmi so that
0x1002aa01 codecs with multiple ports will work properly when switched
back to that patch.

v2: splitted ELD emulation to a separate patch, tlv fixes
v3: adapted to the new hdmi_ops infrastructure, fixed rev3+ vendor id

Vinod Koul 917f4b5cba ALSA: compress: fix drain calls blocking other compress functions
The drain and drain_notify callback were blocked by low level driver untill the
draining was complete. Due to this being invoked with big fat mutex held, others
ops like reading timestamp, calling pause, drop were blocked.

So to fix this we add a new snd_compr_drain_notify() API. This would be required
to be invoked by low level driver when drain or partial drain has been completed
by the DSP. Thus we make the drain and partial_drain callback as non blocking
and driver returns immediately after notifying DSP.
The waiting is done while relasing the lock so that other ops can go ahead.

Currently the ep93xx DMA code is one of the few users relying on the fact
that the compat code uses the dma_data as the filter data for non-DT
channel requests. Since the rest of the core expects this to be a struct
snd_dmaengine_dai_data this isn't terribly helpful this will be changed to
use the already existing filter data so avoid breaking ep93xx by open
coding the current behaviour.

Heiko Stuebner da2f5f4852 ARM: S3C24XX: Fix possible dma selection warning
Currently the s3c sound support selects CONFIG_S3C2410_DMA on s3c24xx
architectures while the generic dma config is enabled by CONFIG_S3C24XX_DMA.

With the way the Kconfig options are layed out currently it is possible
to enable Samsung sound support without enabling the necessary dma support
resulting in warnings like
  warning: (SND_SOC_SAMSUNG && SND_S3C24XX_I2S && SND_S3C2412_SOC_I2S &&
       SND_SOC_SAMSUNG_SMDK2443_WM9710 && SND_SOC_SAMSUNG_LN2440SBC_ALC650)
  selects S3C2410_DMA which has unmet direct dependencies (ARCH_S3C24XX &&
       S3C24XX_DMA && (CPU_S3C2410 || CPU_S3C2442))

Therefore bring the s3c2410 dma support in line with the way the other
s3c24xx SoCs handle this by having the SoC dma-support selected if the generic
s3c dma support is enabled and have the sound support depend on S3C24XX_DMA
on these arches. The s3c2442 is using the same dma descriptors and therefore
also selected S3C2410_DMA.

Kuninori Morimoto 92eba04e4b ASoC: rcar: remove RSND_SSI_CLK_FROM_ADG
R-Car sound has clock pin for each SSI, and sometimes,
these pins are shared with paired SSI.
It may sometimes become "SSI-A clock pin is master" and

SSI-B needs SSI-A clock in this case.

Current R-Car sound driver is using RSND_SSI_xxx flag

But, this information, especially clock master setting,
can be got from ASoC set_fmt settings.

Lars-Peter Clausen fa654e0853 ASoC: dmaengine-pcm: Provide default config
This patch adds some default settings for the generic dmaengine PCM driver for
the case that no config has been supplied. The following defaults are used:
	* Use snd_dmaengine_pcm_prepare_slave_config for preparing the DMA slave
	  config.
	* 512kB for the prealloc buffer size. This value has been chosen based on
	  'feels about right' and is not backed up by any scientific facts. We
	  may need to come up with something smarter in the future but it should
	  work fine for now.

With this infrastructure in place we can finally write DAI drivers which are
independent of the DMA controller they are connected to. This is e.g. useful if
the DAI IP core is reused across different SoCs, but the SoCs uses different DMA
controllers.

Lars-Peter Clausen c0de42bf59 ASoC: dmaengine-pcm: Add support for querying DMA capabilities
Currently each platform making use the the generic dmaengine PCM driver still
needs to provide a custom snd_pcm_hardware struct which specifies the
capabilities of the DMA controller, e.g. the maximum period size that can be
supported. This patch adds code which uses the newly introduced
dma_get_slave_caps() API to query this information from the dmaengine driver.
The new code path will only be taken if the 'pcm_hardware' field of the
snd_dmaengine_pcm_config struct is NULL.

The patch also introduces a new 'fifo_size' field to the
snd_dmaengine_dai_dma_data struct which is used to initialize the
snd_pcm_hardware 'fifo_size' field and needs to be set by the DAI driver.

Mark Brown 78b78f5c01 ASoC: wm8962: Move register initialisation to I2C probe()
This is more idiomatic and is required for robust operation since we must
ensure that the clocking configuration is valid as rapidly as possible.

Geyslan G. Bem f1b4863a87 ALSA: emu10k1: code refactoring
Partially restructures _snd_emu10k1_audigy_init_efx() and
_snd_emu10k1_init_efx() functions.

Be noted that the cast is demanded to use '__user'. So, in these cases,
avoid patches based on the coccinelle 'drop_kmalloc_cast' semantic patch.

Kuninori Morimoto 6833c452c2 ASoC: add snd_soc_of_get_dai_name() default of_xlate
Current snd_soc_of_get_dai_name() needs .of_xlate_dai_name()
callback on each component drivers.
But required behavior on almost all these drivers is
just returns its indexed driver's name.

This patch adds this feature as default behavior.
.of_xlate_dai_name() can overwrite it.

Dmitry Eremin-Solenikov f62aa9b6c9 ALSA: ASoC: pxa: fix pxa2xx-ac97 DAI initialization order
After recent changes to codec/DAI initialization order changes, codec
driver (wm9712 in my case) tries to access codec prior to
pxa2xx_ac97_hw_probe() being called (because DAIs are probed after all
codecs are probed). Move hw-related probe/remove/suspend/resume
functions to pxa2xx-ac97 driver level, instead of DAI level.

Dmitry Eremin-Solenikov beb02cddd6 ALSA: pxa: slightly refactor reset handling
PXA25x also shows some problems when using interrupts during reset
handling. Thus do not use interrupts on all pxa kinds (to detect codec
ready state). Instead use a common mdelay-loop on all platforms to
detect codecs becoming ready.

Clemens Ladisch 82fbb4f7b4 ALSA: add DICE driver
As a start point for further development, this is an incomplete driver
for DICE devices:
- only playback (so no clock source except the bus clock)
- only 44.1 kHz
- no MIDI
- recovery after bus reset is slow
- hwdep device is created, but not actually implemented

Contains compilation fixes by Stefan Richter.

Takashi Iwai a4e9a38b40 ALSA: hda - Move mutex from hda_eld to per_pin in HDMI codec driver
Since the lock is used primarily in patch_hdmi.c, it's better to move
it in the local struct instead of exporting in hda_eld.  The only
functions requiring the lock in hda_eld.c are proc accessors.  So in
this patch, the proc entry and its creation/deletion/accessors are
moved into patch_hdmi.c, together with the mutex lock to pin_spec
struct.

The former proc info functions are exported so that they can be called
from patch_hdmi.c.

Some per_pin fields and ELD contents might be changed dynamically in

The zero-length connection list happens so often on Haswell HDMI, and
it results in warning messages like
    ALSA: hda_codec: invalid CONNECT_LIST verb 5[1]:0

annoying.

Since this is no real error, make it shown only in the verbose debug
mode.
