From: Lad Prabhakar <prabhakar.mahadev-lad...@bp.renesas.com>
The MIPI DSI interface on the RZ/V2H(P) SoC is nearly identical to that of
the RZ/G2L SoC. While the LINK registers are the same for both SoCs, the
D-PHY registers differ. Additionally, the number of resets for DSI on
RZ/V2H(P) is two compared to three on the RZ/G2L.
To accommodate these differences, a SoC-specific
`renesas,r9a09g057-mipi-dsi` compatible string has been added for the
RZ/V2H(P) SoC.
