Subject: [PATCH v4 0/4] Update mdp clk to max supported value to support higher refresh rates
Date:   Thu,  3 Mar 2022 15:09:57 +0530
Message-Id: <1646300401-9063-1-git-send-email-quic_vpolimer@quicinc.com>
Precedence: bulk

Kernel clock driver assumes that initial rate is the
max rate for that clock and was not allowing it to scale
beyond the assigned clock value.

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)
