[PATCH 0/4] MSM8953/MSM8976 ASoC support

[Adam Skladowski]

Introduce support for basic sound card setup on MSM8953/MSM8976
platforms, document new compatibles and introduce support for more dais.
Most of code is sourced from msm8953-mainline fork over github
with some changes implemented by me,some basic changes are 
mentioned in each patch.

[Adam Skladowski]

From: Vladimir Lypak <vladimir.lypak@gmail.com>

Introduce support for audio card on MSM8953/MSM8976 platform.
Main difference between those two is Q6AFE CLK API supported by firmware
which influence way we enable digital codec clock.
Either inside machine driver or outside via q6afe-clocks driver.
