From cadaa773bcf161184fa428180516bae33a7bc667 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 27 Oct 2022 13:57:45 +0200 Subject: [PATCH] arm64: dts: qcom: sm8250: Disable the not yet supported cluster idle state To support the deeper cluster idle state for sm8250 platforms, some additional synchronization is needed between the rpmh-rsc device and the CPU cluster PM domain. 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 --- 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 a5b62cadb129..e276eed1f8e2 100644 --- a/arch/arm64/boot/dts/qcom/sm8250.dtsi +++ b/arch/arm64/boot/dts/qcom/sm8250.dtsi @@ -334,6 +334,7 @@ exit-latency-us = <6562>; min-residency-us = <9987>; local-timer-stop; + status = "disabled"; }; }; }; -- 2.11.0
