This patchset adds support to WSA8810/WSA8815 Class-D Smart Speaker Amplifier which is SoundWire interfaced.
This patchset along with DB845c machine driver and WCD934x codec driver has been tested on SDM845 SoC based DragonBoard DB845c with two WSA8810 and Lenovo YOGA C630 Laptop based on SDM850 with WSA8815 speaker amplifiers.
Most of the code in this driver is rework of Qualcomm downstream drivers used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team.
TODO: Add thermal sensor support in WSA881x.
Thanks, srini
Changes since v8: - Moved soundwire stream handling into this codec as there is strong requirements on sequence of PA and soundwire port enables from hw side.
