Subject: arm64: dts: imx8mn-tqma8mqnl-mba8mx: LVDS overlay: Reduce DSI burst clock to 600Mhz
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1bc7c90aa1cec5ef098d8f686c3f555addcc3509;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: imx8mn-tqma8mqnl-mba8mx: LVDS overlay: Reduce DSI burst clock to 600Mhz

The DSI burst clock frequency is too high resulting in flickering. Reduce
the frequency.

While at it, remove the burst clock from board configuration as it is
display specific.
