Merge tag 'sound-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features; now it's
built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and
Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers; now "make
localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell
AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and
managed resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more
modern and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()
- Extensions to DPCM for use with compressed audio from Liam"
