[PATCH] arm64: dts: qcom: sm8250: drop idlestate for the CPU cluster

From: Amit Pundir
Date: Thu Oct 20 2022 - 11:33:07 EST


Recently added cpuidle states made RB5 (sm8250) devboard
highly unstable and it runs into the following crash
frequently during the boot process:

[ 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

Removing idlestate for the CPU cluster fixes this crash for
the time being, while a proper fix is being worked upon.
