[PATCH v3 4/4] i2c: riic: Add support for R9A09G057 SoC

From: Prabhakar
Date: Tue Mar 19 2024 - 09:27:02 EST


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

Extend the RIIC driver to support the RZ/V2H(P) ("R9A09G057") SoC. It
accomplishes this by appending the compatible string list and passing
the RZ/V2H-specific OF data.
