[PATCH] dt-bindings: memory: renesas,rzg3e-xspi: Document RZ/V2H(P) and RZ/V2N support

From: Prabhakar <prabhakar.csengg@gmail.com>
Date: 2025-06-24 17:16:10
Also in: linux-renesas-soc, lkml
Subsystem: memory controller drivers, open firmware and flattened device tree bindings, the rest · Maintainers: Krzysztof Kozlowski, Rob Herring, Conor Dooley, Linus Torvalds

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

Document support for the Expanded Serial Peripheral Interface (xSPI)
controller found on the Renesas RZ/V2H(P) (R9A09G057) and RZ/V2N
(R9A09G056) SoCs.

The xSPI hardware block on these SoCs is functionally identical to the
one on the RZ/G3E (R9A09G047) SoC. Therefore, the existing driver can be
reused without modification by using `renesas,r9a09g047-xspi` as a
fallback compatible.
