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.
