Subject: [PATCH v7 0/5] Update mdp clk to max supported value to support higher refresh rates

Drop the assigned clock rate property and vote on the mdp clock to

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.

Changes in v6:
- Remove change log in dt patch.
- Fix the leak reference for opp by adding dev_pm_opp_put. (Dmitry)

Changes in v7:
- Update commit message and fix tag. (Stephen/Doug)
