On SM8250 both the display and video clock controllers are powered up by the MMCX power domain. Handle this by linking clock controllers to the proper power domain, and using runtime power management to enable and disable the MMCX power domain. Dependencies: - https://lore.kernel.org/linux-pm/20210603093438.138705-1-ulf.hansson@xxxxxxxxxx/ (merged in 5.14) - https://lore.kernel.org/linux-arm-msm/20210703005416.2668319-1-bjorn.andersson@xxxxxxxxxx/ (pending) Patches resent because I missed one hunk in the PM domains patch, which got stuck in the git index. Now the patch is fixed. Changes since v1: - Rebase on top of Bjorn's patches, removing the need for setting performance state directly. - Move runtime PM calls from GDSC code to generic genpd code. - Always call pm_runtime_enable in the Qualcomm generic clock controller code. - Register GDSC power domains as subdomains of the domain powering the clock controller if there is one. ---------------------------------------------------------------- Dmitry Baryshkov (7): dt-bindings: clock: qcom,dispcc-sm8x50: add mmcx power domain dt-bindings: clock: qcom,videocc: add mmcx power domain PM: domains: Add support for runtime PM clk: qcom: gdsc: enable optional power domain support arm64: dts: qcom: sm8250: remove mmcx regulator clk: qcom: dispcc-sm8250: stop using mmcx regulator clk: qcom: videocc-sm8250: stop using mmcx regulator .../bindings/clock/qcom,dispcc-sm8x50.yaml | 7 ++++ .../devicetree/bindings/clock/qcom,videocc.yaml | 7 ++++ arch/arm64/boot/dts/qcom/sm8250.dtsi | 11 ++----- drivers/base/power/domain.c | 33 +++++++++++++++++++ drivers/clk/qcom/common.c | 37 ++++++++++++++++++---- drivers/clk/qcom/dispcc-sm8250.c | 1 - drivers/clk/qcom/gdsc.c | 5 +++ drivers/clk/qcom/videocc-sm8250.c | 4 --- include/linux/pm_domain.h | 6 ++++ 9 files changed, 91 insertions(+), 20 deletions(-)
