From a1ade6cac5a2adc87099fc040074305804684cf0 Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Thu, 30 Jun 2022 13:14:03 +0300 Subject: [PATCH] arm64: dts: qcom: sdm845: Switch PSCI cpu idle states from PC to OSI Switch from the flat PC idle states of sdm845 to OSI hierarchical idle states. The exceptions are the cheza plaftorms, which need to remain with PC idle states. So in order allow all the other platforms to switch, while cheza platforms to remain the same, replace the PC idle states with the OSI ones in the main SDM845 dtsi, and then override the inherited OSI states with PC ones, delete inherited psci cpus nodes, domain idle states and power domain properties.
