[PATCH v5 01/17] media: dt-bindings: renesas,rzg2l-csi2: Document Renesas RZ/V2H(P) SoC

Tommaso Merciai

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

The MIPI CSI-2 block on the Renesas RZ/V2H(P) SoC is similar to the one
found on the Renesas RZ/G2L SoC, with the following differences:
- A different D-PHY
- Additional registers for the MIPI CSI-2 link
- Only two clocks

Add a new compatible string, `renesas,r9a09g057-csi2`, for the RZ/V2H(P)
SoC.
