[PATCH v5 1/3] dt-bindings: mmc: renesas,sdhi: Document RZ/V2H(P) support

From: Prabhakar
Date: Wed Jul 24 2024 - 14:23:10 EST


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

The SD/MMC block on the RZ/V2H(P) ("R9A09G057") SoC is similar to that
of the R-Car Gen3, but it has some differences:
- HS400 is not supported.
- It has additional SD_STATUS register to control voltage,
power enable and reset.
- It supports fixed address mode.

To accommodate these differences, a SoC-specific 'renesas,sdhi-r9a09g057'
compatible string is added.
