QCM6490 uses Trustzone as firmware whereas SC7280 uses arm trusted firmware. The PSCI suspend param and the number of domain-idle-states supported is different in Trustzone for cluster sleep. Move the arm trusted firmware supported domain-idle-states in chrome specific sc7280-chrome-common.dtsi and add the Trustzone supported sleep states as default domain-idle-states in sc7280.dtsi Signed-off-by: Maulik Shah <quic_mkshah@quicinc.com> --- Changes in v2: - Move chrome specific domain-idle-states to sc7280-chrome-common.dtsi - Keep LA+LE+WP+friends values as default - Add additional cluster sleep states - Link to v1: https://lore.kernel.org/lkml/20240105070223.11415-1-quic_mkshah@quicinc.com/ --- arch/arm64/boot/dts/qcom/sc7280-chrome-common.dtsi | 17 +++++++++++++ arch/arm64/boot/dts/qcom/sc7280.dtsi | 28 ++++++++++++++++------ 2 files changed, 38 insertions(+), 7 deletions(-) --- base-commit: bffdfd2e7e63175ae261131a620f809d946cf9a7 change-id: 20240109-qcm6490_cluster_sleep-2c4f175814b6 Best regards,
