Commit Message

Krzysztof Kozlowski May 12, 2023, 4:04 p.m. UTC 
Add Qualcomm Aqstic WCD9385 audio codec on two Soundwire interfaces: RX
and TX.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

Not tested and not really verified against schematics (no access).
MTP added based on downstream DTS.
