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) Changes in v5: - Add change to set mdp clk to max frequency in opp table during mdp probe/bind.
