This should be "renesas,r8a77961-lvds".
To handle that, both the DT bindings[1] and the driver[2] should
be updated.

[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
