Merge tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull updates of sound stuff from Takashi Iwai:
 "Here is the first big update chunk of sound stuff for 3.4-rc1.

  In the common sound infrastructure, there are a few changes for
  dynamic PCM support (used in ASoC) and a few clean-ups.  Majority of
  changes are found, as usual, in HD-audio and ASoC.

  Some highlights of HD-audio changes:

   - All the long-standing static quirk codes for Realtek codec were
     finally removed by fixing and extending the Realtek auto-parser.

   - The mute-LED control is standardized over all HD-audio codec
     drivers using the extended vmaster hook.

   - The vmaster slave mixer elements are initialized to 0dB as default
     so that the user won't be annoyed by the silent output after
     updates, e.g.  due to the additions of new elements.

   - Other many fix-ups for the misc HD-audio devices.

  In the ASoC side, this is a very active release, including a quite a
  few framework enhancements.  Some highlights:

   - Support for widgets not associated with a CODEC, an important part
     of the dynamic PCM framework.

   - A library factoring out the common code shared by dmaengine based
     DMA drivers contributed by Lars-Peter Clausen.  This will save a
     lot of code and make it much easier to deploy enhancements to
     dmaengine.

   - Support for binary controls, used for providing runtime
     configuration of algorithm coefficients.

   - A new DAPM widget type for regulator supplies allowing drivers for
     devices that can power down unused supplies while active to do
     without any per-driver code.

   - DAPM widgets for DAIs, initially giving a speed boost for playback
     startup and shutdown and also the basis for CODEC<->CODEC DAI link
     support.

   - Support for specifying the number of significant bits on audio
     interfaces, useful for allowing applications to know how much
     effort to put into generating data for a larger sample format.

   - Conversion of the FSI driver used on some SH processors to
     DMAEngine.

   - Conversion of EP93xx drivers to DMAEngine.

   - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
     WM2200.

   - Move audmux driver from arc/arm to sound/soc

   - McBSP move from arch/ to sound/ and updates

  Also, a few small updates and fixes for other drivers like au88x0,
  ymfpci, USB 6fire, USB usx2yaudio are included."
