Qualcomm WCD9380/WCD9385 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire device RX and
TX respectively, supporting 4 x ADCs, ClassH, Ear, Aux PA, 2xHPH,
7 x TX diff inputs, 8 DMICs, MBHC.

My bot found errors running 'make dt_binding_check' on your patch:

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
