RZ/G2L LCDC documents both port@0 and port@1 that is described here in [1] [1] https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/Documentation/devicetree/bindings/display/renesas,rzg2l-du.yaml?h=next-20240702#n59 Unfortunately missed to add port@1 as required property. Currently there is no user for the DPI interface and there is no DPI interface support in display driver. So, there is nothing for ABI breakage. I will mention in the commit description that "currently there is no user for the DPI interface and hence there won't be any ABI breakage for adding port@1 as required property for RZ/G2L and RZ/V2L SoCs".

That seems reasonable. You can add my Acked-by with that wording update. Thanks, Conor.

Document DU found in RZ/G2UL SoC. The DU block is identical to RZ/G2L SoC, but has only DPI interface. While at it, add missing required property port@1 for RZ/G2L and RZ/V2L SoCs.
