Subject: [PATCH v5 01/12] dt-bindings: display: renesas,rzg2l-du: Add support for RZ/V2H(P) SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

The DU block on the RZ/V2H(P) SoC is identical to the one found on the
RZ/G2L SoC. However, it only supports the DSI interface, whereas the
RZ/G2L supports both DSI and DPI interfaces.

Due to this difference, a SoC-specific compatible string
'renesas,r9a09g057-du' is added for the RZ/V2H(P) SoC.
