ASoC: Updates for v3.19
Lots and lots of changes this time around, the usual set of driver
updates and a huge bulk of cleanups from Lars-Peter. Probably the most
interesting thing for most users is the Intel driver updates which will
(with some more machine integration work) enable support for newer x86
laptops.
- Conversion of AC'97 drivers to use regmap, bringing us closer to the
removal of the ASoC level I/O code.
- Clean up a lot of old drivers that were open coding things that have
subsequently been implemented in the core.
- Some DAPM performance improvements.
- Removal of the now seldom used CODEC mutex.
- Lots of updates for the newer Intel SoC support, including support
for the DSP and some Cherrytrail and Braswell machine drivers.
- Support for Samsung boards using rt5631 as the CODEC.
- Removal of the obsolete AFEB9260 machine driver.
- Driver support for the TI TS3A227E headset driver used in some
Chrombeooks.
