The proper way to convert between the device tree properties from the vendor tree to the upstream PSCI device tree properties is: entry-latency-us = qcom,time-overhead - qcom,latency-us which gives entry-latency-us = 210 - 80 = 130 Fixes: f6aee7af59b6 ("arm64: dts: qcom: msm8996: Add PSCI cpuidle low power states") Signed-off-by: Niklas Cassel --- arch/arm64/boot/dts/qcom/msm8996.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/qcom/msm8996.dtsi b/arch/arm64/boot/dts/qcom/msm8996.dtsi index b7cf2a17dcb5..e8c03b5c8990 100644 --- a/arch/arm64/boot/dts/qcom/msm8996.dtsi +++ b/arch/arm64/boot/dts/qcom/msm8996.dtsi @@ -174,7 +174,7 @@ compatible = "arm,idle-state"; idle-state-name = "standalone-power-collapse"; arm,psci-suspend-param = <0x00000004>; - entry-latency-us = <40>; + entry-latency-us = <130>; exit-latency-us = <80>; min-residency-us = <300>; }; -- 2.21.0
