This patchset aims at adding msm8916-wcd 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. This series also add a new macro SOC_SINGLE_S8_TLV() which is used in the codec driver to control gain on a 8 bit signed gain control register. 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. 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 v4.6 with lpass driver Headset (Mic and speakers), Secondary Mic and Loudspeaker on DB410C. DMIC should work too. Thanks, srini Changes since RFC v1 (https://lkml.org/lkml/2016/2/16/710) - Lot of code cleanup as suggest by Mark Brown. - Fixed bindings as suggested by Mark Rutland. - merged all the patches to one as spliting the patches did not help review.
