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

From: Prabhakar
Date: Tue Jun 24 2025 - 13:16:21 EST


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

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.
