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"
