    Subject[PATCH 5.15 309/913] ARM: dts: imx: Add missing LVDS decoder on M53Menlo
    Date
    From: Marek Vasut <marex@denx.de>

    [ Upstream commit 0c6f71176ea43d6f4003a4d57f7bb518c5ad6145 ]

    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")
