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) Fixes: 62fbdce91("arm64: dts: qcom: sc7280: add display dt nodes") Signed-off-by: Vinod Polimera Reviewed-by: Stephen Boyd --- arch/arm64/boot/dts/qcom/sc7280.dtsi | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sc7280.dtsi b/arch/arm64/boot/dts/qcom/sc7280.dtsi index baf1653..408cf6c 100644 --- a/arch/arm64/boot/dts/qcom/sc7280.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7280.dtsi @@ -2856,9 +2856,6 @@ "ahb", "core"; - assigned-clocks = <&dispcc DISP_CC_MDSS_MDP_CLK>; - assigned-clock-rates = <300000000>; - interrupts = ; interrupt-controller; #interrupt-cells = <1>; @@ -2892,11 +2889,9 @@ "lut", "core", "vsync"; - assigned-clocks = <&dispcc DISP_CC_MDSS_MDP_CLK>, - <&dispcc DISP_CC_MDSS_VSYNC_CLK>, + assigned-clocks = <&dispcc DISP_CC_MDSS_VSYNC_CLK>, <&dispcc DISP_CC_MDSS_AHB_CLK>; - assigned-clock-rates = <300000000>, - <19200000>, + assigned-clock-rates = <19200000>, <19200000>; operating-points-v2 = <&mdp_opp_table>; power-domains = <&rpmhpd SC7280_CX>;
