Thanks for the review. Moved the chrome specific changes to sc7280-chrome-common.dtsi in v2. > >> arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts | 4 ++++ >> arch/arm64/boot/dts/qcom/qcm6490-idp.dts | 4 ++++ >> 2 files changed, 8 insertions(+) >> >> diff --git a/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts b/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts >> index 176898c9dbbd..b56f6f26d96f 100644 >> --- a/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts >> +++ b/arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts >> @@ -446,6 +446,10 @@ >> }; >> }; >> >> +&CLUSTER_SLEEP_0 { >> + arm,psci-suspend-param = <0x4100b344>; >> > > I think the residency times should also be updated here. > > Moreover, I'm seeing additional sleep states here (APSS PC, CX RET > and this one being AOSS SLEEP), with values 0x4<<4, 0x134<<4, > 0xb34<<4 (the one you added here) respectively. > > Could you please add them as well, similar to [1]? > > Konrad > > [1] https://lore.kernel.org/linux-arm-msm/20230619-topic-sc8280xp-idle-v2-1-cde50bf02f3c@linaro.org/ Sure, added additional sleep stats with updated residency time in v2.

QCM6490 uses Trustzone as firmware whereas SC7280 uses arm trusted firmware. The PSCI suspend param is different in Trustzone for cluster sleep. Update the same for qcm6490 based idp and fairphone fp5 boards.
