Subject: [PATCH v2 01/18] media: dt-bindings: renesas,rzg2l-csi2: Document Renesas RZ/V2H(P) SoC
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...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.

Changes since v1:
- Dropped empty line as suggested by LPinchart
- Fixed minItems into else conditional block as suggested by RHerring
