Merge tag 'sound-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into next

Pull sound updates from Takashi Iwai:
 "At this time, majority of changes come from ASoC world while we got a
  few new drivers in other places for FireWire and USB.  There have been
  lots of ASoC core cleanups / refactoring, but very little visible to
  external users.

  ASoC:
   - Support for specifying aux CODECs in DT
   - Removal of the deprecated mux and enum macros
   - More moves towards full componentisation
   - Removal of some unused I/O code
   - Lots of cleanups, fixes and enhancements to the davinci, Freescale,
     Haswell and Realtek drivers
   - Several drivers exposed directly in Kconfig for use with
     simple-card
   - GPIO descriptor support for jacks
   - More updates and fixes to the Freescale SSI, Intel and rsnd drivers
   - New drivers for Cirrus CS42L56, Realtek RT5639, RT5642 and RT5651
     and ST STA350, Analog Devices ADAU1361, ADAU1381, ADAU1761 and
     ADAU1781, and Realtek RT5677

  HD-audio:
   - Clean up Dell headset quirks
   - Noise fixes for Dell and Sony laptops
   - Thinkpad T440 dock fix
   - Realtek codec updates (ALC293,ALC233,ALC3235)
   - Tegra HD-audio HDMI support

  FireWire-audio:
   - FireWire audio stack enhancement (AMDTP, MIDI), support for
     incoming isochronous stream and duplex streams with timestamp
     synchronization
   - BeBoB-based devices support
   - Fireworks-based device support

  USB-audio:
   - Behringer BCD2000 USB device support

  Misc:
   - Clean up of a few old drivers, atmel, fm801, etc"
