Add CPU idle-state nodes and power-domains in Qualcomm sm6115 SoC dtsi. Signed-off-by: Bhupesh Sharma <bhupesh.sharma@xxxxxxxxxx> --- Changes since v2: - v2 can be viewed here: https://lore.kernel.org/linux-arm-msm/20230330193303.612475-1-bhupesh.sharma@xxxxxxxxxx/ - v2 has no functional change, except I tested using debugfs/sysfs and the idle states looked sane to me. Changes since v1: - v1 can be viewed here: https://lore.kernel.org/lkml/e5cda4cf-5c2a-a7ed-9e1d-1fe9f2cbef40@xxxxxxxxxx - Addressed Konrad's comments on v1 and added GDHS and Power Collapse cluster power states. arch/arm64/boot/dts/qcom/sm6115.dtsi | 136 +++++++++++++++++++++++++++ 1 file changed, 136 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sm6115.dtsi b/arch/arm64/boot/dts/qcom/sm6115.dtsi index 631ca327e064..0cfccde38f70 100644 --- a/arch/arm64/boot/dts/qcom/sm6115.dtsi +++ b/arch/arm64/boot/dts/qcom/sm6115.dtsi @@ -47,6 +47,8 @@ CPU0: cpu@0 { enable-method = "psci";
