Subject: [PATCH] arm64: dts: qcom: qrb5165-rb5: Disable cpuidle states
Date: Tue, 18 Oct 2022 20:23:48 +0530 [thread overview]
Message-ID: <20221018145348.4051809-1-amit.pundir@linaro.org> (raw)
Disable cpuidle states for RB5. These cpuidle states
made the device highly unstable and it runs into the
following crash frequently:
[ T1] vreg_l11c_3p3: failed to enable: -ETIMEDOUT
[ T1] qcom-rpmh-regulator 18200000.rsc:pm8150l-rpmh-regulators: ldo11: devm_regulator_register() failed, ret=-110
[ T1] qcom-rpmh-regulator: probe of 18200000.rsc:pm8150l-rpmh-regulators failed with error -110
Fixes: 32bc936d7321 ("arm64: dts: qcom: sm8250: Add cpuidle states")
