From 7f492d48f08207e4ee23edc926b11de9f720aa61 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Tue, 30 Jan 2024 18:48:08 +0200 Subject: [PATCH] arm64: dts: qcom: qrb2210-rb1: disable cluster power domains If cluster domain idle state is enabled on the RB1, the board becomes significantly less responsive. Under certain circumstances (if some of the devices are disabled in kernel config) the board can even lock up. It seems this is caused by the MPM not updating wakeup timer during CPU idle (in the same way the RPMh updates it when cluster idle state is entered). Disable cluster domain idle for the RB1 board until MPM driver is fixed to cooperate with the CPU idle states.
