Until that is supported, let's disable the cluster idle state. This fixes a problem that has been reported for the Qcom RB5 platform (see below), but most likely other sm8250 platforms suffers from similar issues, so let's make the fix generic for sm8250. vreg_l11c_3p3: failed to enable: -ETIMEDOUT qcom-rpmh-regulator 18200000.rsc:pm8150l-rpmh-regulators: ldo11: devm_regulator_register() failed, ret=-110 qcom-rpmh-regulator: probe of 18200000.rsc:pm8150l-rpmh-regulators failed with error -110 Reported-by: Amit Pundir Fixes: 32bc936d7321 ("arm64: dts: qcom: sm8250: Add cpuidle states") Signed-off-by: Ulf Hansson Tested-by: Amit Pundir Reviewed-by: Sudeep Holla Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20221027115745.240516-1-ulf.hansson@linaro.org Signed-off-by: Sasha Levin --- arch/arm64/boot/dts/qcom/sm8250.dtsi | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/boot/dts/qcom/sm8250.dtsi b/arch/arm64/boot/dts/qcom/sm8250.dtsi index bc773e210023..052b4dbc1ee4 100644 --- a/arch/arm64/boot/dts/qcom/sm8250.dtsi +++ b/arch/arm64/boot/dts/qcom/sm8250.dtsi @@ -334,6 +334,7 @@ CLUSTER_SLEEP_0: cluster-sleep-0 { exit-latency-us = <6562>; min-residency-us = <9987>; local-timer-stop; + status = "disabled"; }; }; }; -- 2.35.1
