[alsa-devel] [PATCH v4 0/9] ASoC: Intel: Skylake: Driver updates

[jeeja.kp at intel.com]

From: Jeeja KP <jeeja.kp at intel.com>

This patch series includes driver updates for the handling scenarios 
during System S0/S3 transitions when audio stream is stopped during
system.
o move DMA configuration in DSP Gateway Module widget event handler to
ensure DMA is configured after resume. 
o Enable SSP MLCK using Supply widget. This will ensure the MCLK is
enabled when the widget is power on.
o Check DMA decouple register state before coupling/decoupling the DMA.
o In case of HDMI pass-through pipe, reset only the FE Pipe when stream
in in XRUN state.
o Resume the stream from HW renderer position.
o HDMI Codec pin and converter state need to be restored when stream
is resumed.

Changes in v2:
 - Addressed Mark's comment on patch 1, split this into 2 as this had
additional changes other than configuring the DMA.
 - Addressed Takashi's comment on the usage of snd_hdac_updatel() 

Changes in v3:
 - Addressed Takashi's comment on superfluous shift used in reading the
value of PPCTL register and also cleaned the condition for updating
the reg value.

Changes in v4:
 - Acked by Takashi for patch "ALSA: hda: check stream decoupled register
   state".
 - Removed compilation warning in patch "ASoC: hdac_hdmi: Enable pin and
   converter in prepare".
 - Remove 4 patches which are already applied.
