Merge branch 'for-linus' into for-next

2014-11-28T17:30:19+00:00

The commit [7a2e9ddc: ALSA: usb-audio: Add native DSD support for
Denon/Marantz DACs] requires the new format definition that has
landed only in for-next branch.

ALSA: pcm: Add big-endian DSD sample formats and fix XMOS DSD sample format

2014-11-21T14:13:28+00:00

This patch fixes XMOS DSD sample format to DSD_U32_BE and also adds
DSD_U16_BE and DSD_U32_BE sample formats.

ALSA: pcm: Add snd_pcm_stop_xrun() helper

2014-11-09T17:20:40+00:00

Add a new helper function snd_pcm_stop_xrun() to the standard sequnce
lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the
existing open codes with this helper.

The function checks the PCM running state to prevent setting the wrong
state, too, for more safety.

ALSA: pcm: Add xrun_injection proc entry

2014-11-04T13:09:16+00:00

This patch adds a new proc entry for PCM substreams to inject an
XRUN.  When a PCM substream is running and any value is written to its
xrun_injection proc file, the driver triggers XRUN.  This is a useful
feature for debugging XRUN and error handling code paths.

Note that this entry is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is
set.

ALSA: pcm: Convert params_*() with static inline functions

2014-10-30T14:42:32+00:00

... and add proper kerneldoc comments.
There is no big reason to keep them as macros.  Static inline
functions are safer in general, and suitable for kerneldoc, too.

ALSA: pcm: More kerneldoc updates

2014-10-30T14:42:27+00:00

Add proper kerneldoc comments to the exported functions.

ALSA: pcm: Use static inline for snd_pcm_lib_alloc_vmalloc_buffer()

2014-10-30T12:48:29+00:00

... instead of #if 0 hack.  It's more straightforward and obvious.

ALSA: pcm: add new DSD sampleformat for native DSD playback on XMOS based devices

2014-09-08T15:11:00+00:00

XMOS based USB DACs with native DSD support expose this feature via a USB
alternate setting. The audio format is either 32-bit raw or a 32-bit PCM format.
To utilize this feature on linux this patch introduces a new 32-bit DSD
sampleformat DSD_U32_LE.
A follow up patch will add a quirk for XMOS based devices to utilize the new format.
Further patches will add support to alsa-lib.

ALSA: pcm: Uninline snd_pcm_stream_lock() and _unlock()

2014-09-03T12:04:18+00:00

The previous commit for the non-atomic PCM ops added more codes to
snd_pcm_stream_lock() and its variants.  Since they are inlined
functions, it resulted in a significant code size bloat.  For reducing
the size bloat, this patch changes the inline functions to the normal
function calls.  The export of rwlock and rwsem are removed as well,
since they are referred only in pcm_native.c now.
