[alsa-devel] [PATCH v6 0/5] ASoC: Add support to Qualcomm msm8916-wcd multi codec

[Srinivas Kandagatla]

This patchset aims at adding msm8916-wcd multi codec support.
msm8916-wcd codec is found in Qualcomm msm8916 and apq8016 processors.
This codec IP is split in to two parts(Digital & Analog), Analog part
is integrated in to PMIC PM8916 and the digital part is integrated into
Application processor. Register access to the analog part is done via
SPMI interface to PMIC, and registers on the Application processor are
memory mapped. Data transfer between Analog and Digital Die is done via
a internal bus called PDM.

Most of this driver is ported from downstream Andriod v3.10 kernel.
Jack support and Headset button detection code is not added in to this
series.

First two patches add digital and analog codec support and the follow on
patches add routes and multicodec support to the sound card and
finally dts patch for board.

This codec support:
 - 3 Microphones: Primary Mic(Handset mic), Headset Mic and Secondary Mic.
 - 2 Digital Microphones.
 - 2 Mic Bias Circuits.
 - Earpiece
 - Headset
 - Loud Speaker.
 - Jack Detect.
 - Headset Button detection circuit.

Tested this code on v4.9-rc1 with for Headset (Mic and speakers), Secondary Mic
and Loudspeaker on DB410C. DMIC should work too.
Last DT patch is on top of v4.9-rc1 which get analog audio working. 

Thanks,
srini
