There may be 2 pcm streams for a same DAI at most, and these 2
streams should have different hsw_pcm_data, e.g. they have
different persistent data, so here we need split hsw_pcm_data
for playback and capture, to make sure they won't be mixed
and keep cleaned.

A DAI may have 2 streams(playback/capture) and different modules

On Cherrytrail and Braswell, the I2S BCLK is 100FS which cannot be supported
by RT5672 in slave mode and can cause noise. This patch selects codec ASRC
clock source to track I2S1 clock so that codec ASRC can be enabled to suppress
the noise.

When codec is in slave mode, ASRC can suppress noise for asynchronous
MCLK and LRCLK or special I2S format. This patch defines an API to select
the clock source for specified filters. And the codec driver will turn on ASRC
for these filters if ASRC is selected as their clock source.

The sst-haswell-pcm driver is a new user of CONFIG_PM_RUNTIME.
However, after commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if
PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so
#ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to
depend on CONFIG_PM.

The Arcam rPAC seems to have the same problem - whenever anything
(alsamixer, udevd, 3.9+ kernel from 60af3d037e, ..) attempts to
access mixer / control interface of the card, the firmware "locks up"
the entire device, resulting in
SNDRV_PCM_IOCTL_HW_PARAMS failed (-5): Input/output error
from alsa-lib.
Other operating systems can somehow read the mixer (there seems to be
playback volume/mute), but any manipulation is ignored by the device
(which has hardware volume controls).

ASoC: Merge window fixes for v3.19
A smattering of driver specific fixes here, some more cleanup of the
Exynos7 and Intel ACPI support plus a fix for register cache sync on the
pcm512x driver which has been lurking for a while.
A crash can occur on some platforms where adsp is enumerated but codec is not
matched. Define codec_id as a pointer intead of an array so that it gets
initialized to NULL for the terminating element of sst_acpi_bytcr[] and
sst_acpi_chv[].

Skylake and Haswell have the same behavior on display audio. So this patch
applys Haswell fix-ups to Skylake.

In case of error, the function platform_device_register_data()
returns ERR_PTR() and never returns NULL. The NULL test in the
return value check should be replaced with IS_ERR().

... for distinguishing whether it's explicitly enabled via a user hint
or enabled by a driver as a fallback. Now the former case corresponds
to HDA_HINT_STEREO_MIX_ENABLE while the latter to
HDA_HINT_STEREO_MIX_AUTO.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
When the stereo mix input is explicitly enabled via a user hint, the
driver should create always a capture source enum ctl and disable the
auto-mic switch. Otherwise the behavior gets confused. For doing it,
this patch just sets spec->suppress_auto_mic flag appropriately.

This patch adds codec ID (0x80862809) and module alias for Skylake
display codec.

This code tends to use unsigned variables by default and it causes
signedness bugs when we use negative variables for error handling.
The "i" and "j" variables are used to iterated over small positive
values and so they should be type "int". The "len" variable doesn't
*need* to be signed but it should be signed to make the code easier to
read and audit.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.
