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. --- arch/arm64/boot/dts/qcom/sm8450-hdk.dts | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
