[PATCH v2] ARM: dts: imx: Add missing LVDS decoder on M53Menlo

Marek Vasut marex at denx.de
Sun Feb 6 14:11:23 PST 2022


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")
