Drop the assigned clock rate property and vote on the mdp clock as per calculated value during the usecase. Changes in v2: - Remove assigned-clock-rate property and set mdp clk during resume sequence. - Add fixes tag. Changes in v3: - Remove extra line after fixes tag.(Stephen Boyd) - Add similar changes for sc7180, sdm845 which uses opp table for voting mdp clk.(Stephen Boyd) - Drop patch: "drm/msm/disp/dpu1: set mdp clk to the maximum frequency in opp table" Changes in v4: - Add similar change for sm8250.(Dmitry) Vinod Polimera (4): arm64/dts/qcom/sc7280: remove assigned-clock-rate property for mdp clk arm64/dts/qcom/sc7180: remove assigned-clock-rate property for mdp clk arm64/dts/qcom/sdm845: remove assigned-clock-rate property for mdp clk arm64/dts/qcom/sm8250: remove assigned-clock-rate property for mdp clk arch/arm64/boot/dts/qcom/sc7180.dtsi | 9 ++------- arch/arm64/boot/dts/qcom/sc7280.dtsi | 9 ++------- arch/arm64/boot/dts/qcom/sdm845.dtsi | 9 ++------- arch/arm64/boot/dts/qcom/sm8250.dtsi | 9 ++------- 4 files changed, 8 insertions(+), 28 deletions(-) Reviewed-by: Stephen Boyd
