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. Signed-off-by: Abel Vesa --- Changes since v1: * fixed the commit message as suggested by Krzysztof * dropped blank line sdm845 dtsi * renamed sdm845 dtsi psci subnodes to power domain cpus and cluster * fixed indentation for idle states in cheza dtsi arch/arm64/boot/dts/qcom/sdm845-cheza.dtsi | 132 ++++++++++++++++++++ arch/arm64/boot/dts/qcom/sdm845.dtsi | 135 ++++++++++++--------- 2 files changed, 213 insertions(+), 54 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sdm845-cheza.dtsi b/arch/arm64/boot/dts/qcom/sdm845-cheza.dtsi index e7e4cc5936aa..13d3d7328210 100644 --- a/arch/arm64/boot/dts/qcom/sdm845-cheza.dtsi +++ b/arch/arm64/boot/dts/qcom/sdm845-cheza.dtsi @@ -145,6 +145,138 @@ panel_in_edp: endpoint { };
