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.
