This patchset adds support for Qualcomm WCD938X codec.
Qualcomm WCD9380/WCD9385 Codec is a standalone Hi-Fi audio codec IC connected over SoundWire. This device has two SoundWire devices, RX and TX respectively supporting 4 x ADCs, ClassH, Ear, Aux PA, 2xHPH, 7 x TX diff inputs, 8 DMICs and MBHC.
Eventhough this device has two SoundWire devices, only tx device has access to main codec Control/Status Registers!
For codec driver to be functional it would need both tx and rx Soundwire devices to be up and this is taken care by using device component framework and device-links are used to ensure proper pm dependencies. Ex tx does not enter suspend before rx or codec is suspended.
This patchset along with other SoundWire patches on the list have been tested on SM8250 MTP device.
Thanks, srini
Changes since v8: - moved Kconfig and Makefile changes to last patch as suggested by Mark - removed array of enums and used static entries instead. Suggested by Mark - return true if put succeeds, Suggested by Mark - removed some unneeded semi-colons in switch
