[PATCH v4 4/6] arm64: dts: freescale: imx8mp-skov: configure LDB clock automatically
From: Ahmad Fatoum
Date: Tue Feb 18 2025 - 13:28:01 EST
The comment in the DT mentions that "currently it is not possible to let
display clocks configure automatically, so we need to set them manually".
Since commit ff06ea04e4cf ("clk: imx: clk-imx8mp: Allow media_disp pixel
clock reconfigure parent rate"), this is no longer the case.
Make use of this new functionality by dropping the now unneeded
assigned-clock-rates in &media_blk_ctrl.
