Subject: [PATCH 1/2] arm64: dts: qcom: sm8550-qrd: add sound card
Date:   Mon, 12 Jun 2023 19:37:57 +0200
Message-Id: <20230612173758.286411-1-krzysztof.kozlowski@linaro.org>
MIME-Version: 1.0

Precedence: bulk

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@linaro.org>

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:
