[PATCH 2/3] arm64: dts: imx8mm-tqma8mqml-mba8mx: LVDS overlay: Reduce DSI burst clock

From: Alexander Stein

Date: Tue Mar 10 2026 - 09:46:07 EST


The DSI burst clock frequency is to high resulting in flickering. Reduce
the frequency.
While at it, remove the burst clock from board configuration as it is
display specific.
