Merge tag 'asoc-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into topic/asoc

This has been a very active release for ASoC, as well as the usual raft
of bugfixes and driver updates there's quite a few framework enhancements.
Most are either small or are laying the groundwork for user visible
features (especially dynamic PCM), the most directly visible change is
the dmaengine library.  There's also a bunch of regmap API enhancements
pulled into the tree so that either the framework or drivers can take
advantage of the new features.

Changes include:

- 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.

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