Subject: [PATCH] dt-bindings: mmc: renesas,sdhi: Document RZ/T2H and RZ/N2H support
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
Add SDHI bindings for the Renesas RZ/T2H (a.k.a R9A09G077) and RZ/N2H
(a.k.a R9A09G087) SoCs. Use `renesas,sdhi-r9a09g057` as a fallback since
the SD/MMC block on these SoCs is identical to the one on RZ/V2H(P),
allowing reuse of the existing driver without modifications.
Update the binding schema to reflect differences: unlike RZ/V2H(P),
RZ/T2H and RZ/N2H do not require the `resets` property and use only a
single clock instead of four.
