Subject[PATCH] arm64: dts: qcom: sm8450-hdk: use recommended drive strength for speaker SD_N
Date
Downstream DTS (and sc8280xp-lenovo-thinkpad-x13s with the same
speakers) uses 16 mA drive strength for the WSA8835 speaker SD_N
reset/shutdown pin. Use the same for HDK8450, as it is seem the
recommended value.

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

Not adding Fixes tag because 4 mA seems to work, so this is just
choosing safer value, based on downstream DTS.
