Use the same for HDK8450, as it is seem the recommended value. Signed-off-by: Krzysztof Kozlowski --- 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(-) diff --git a/arch/arm64/boot/dts/qcom/sm8450-hdk.dts b/arch/arm64/boot/dts/qcom/sm8450-hdk.dts index 9fa1a83d9554..e04de4bb7fae 100644 --- a/arch/arm64/boot/dts/qcom/sm8450-hdk.dts +++ b/arch/arm64/boot/dts/qcom/sm8450-hdk.dts @@ -754,7 +754,7 @@ &tlmm { spkr_1_sd_n_active: spkr-1-sd-n-active-state { pins = "gpio1"; function = "gpio"; - drive-strength = <4>; + drive-strength = <16>; bias-disable; output-low; }; @@ -762,7 +762,7 @@ spkr_1_sd_n_active: spkr-1-sd-n-active-state { spkr_2_sd_n_active: spkr-2-sd-n-active-state { pins = "gpio89"; function = "gpio"; - drive-strength = <4>; + drive-strength = <16>; bias-disable; output-low; };
