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 Changes since v5: - Fixed DT example style and compatible string as suggested by Rob. - Added Rob's acks to 2 patches. Changes since v4: - Fixed various C-style related issues reported by Mark - Added shutdown call to clear things setup in startup, spotted by Mark. - Rearranged code to make it more readble suggested by Mark. - Converted dmic clk to a dapm supply spotted by Mark. - Added example in dt bindings to show support of multicodec. - Removed two patches from this list as they are already applied in sound tree. Changes since v3: - Split the codec to 2 seperate codecs digital and analog, suggested by Mark and Kenneth. - Addressed various suggestions from Mark and Kenneth.
