ASoC: codecs: add WSA883x support
Merge series from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:
This patchset adds support for WSA883x smart speaker amplifier codec
connected via SoundWire. This codec also has a temperature sensor used
for speaker protection, support for this is not added yet.
Most of the code is derived from Qualcomm downstream msm-5.10 kernel.
Thanks to Patrick Lai's Team.
This codec is tested on SM8450 MTP.
