Subject: ARM: dts: imx: Add missing LVDS decoder on M53Menlo
Git-commit: 0c6f71176ea43d6f4003a4d57f7bb518c5ad6145
Patch-mainline: v5.18-rc1
References: git-fixes
The M53Menlo display unit uses an LVDS-to-DPI bridge, TI DS90CF364A.
Describe this bridge in DT, otherwise the DT incorrectly describes
DPI panel attached directly to LVDS source.
Fixes: 716be61d1869 ("ARM: dts: imx53: Add Menlosystems M53 board")
