[PATCH 1/2] arm64: dts: qcom: sm8550-qrd: add sound card

From: Krzysztof Kozlowski
Date: Mon Jun 12 2023 - 13:39:28 EST


Add the sound card node with tested playback over WSA8845 speakers and
WCD9385 headset over USB Type-C. The recording links were not tested,
but should be similar to previous platforms.

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

Bindings for the sound card were not sent to LKML. Work-in-progress is
available here:
https://github.com/krzk/linux/tree/n/audio-wsa884x-on-top-of-wip-sm8450-audio-on-next

Depends on my previous patch adding WSA8845 speakers:
