+ lvds0: lvds@feb90000 { + compatible = "renesas,r8a7796-lvds";This should be "renesas,r8a77961-lvds". To handle that, both the DT bindings[1] and the driver[2] should be updated. [1] Documentation/devicetree/bindings/display/bridge/renesas,lvds.yaml [2] drivers/gpu/drm/rcar-du/rcar_lvds.c
Ok, will redo that way, although I don't really understand what for to have different compatible strings for exactly same IP inside different chips.
Also note that arch/arm64/boot/dts/renesas/r8a77951.dtsi currently has renesas,r8a7795-lvds Nikita
