[PATCH v3 3/3] arm64/dts/qcom/sdm845: remove assigned-clock-rate property for mdp clk

From: Vinod Polimera
Date: Thu Mar 03 2022 - 03:09:11 EST


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.
