From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Document support for the I2C Bus Interface (RIIC) available in the Renesas RZ/V2H (R9A09G057) SoC. The RIIC interface in the Renesas RZ/V2H differs from RZ/A in a couple of ways: - Register offsets for the RZ/V2H SoC differ from those of the RZ/A SoC. - RZ/V2H register access is 8-bit, whereas RZ/A supports 8/16/32-bit. - RZ/V2H has some bit differences in the slave address register. To accommodate these differences in the existing driver, a new compatible string "renesas,riic-r9a09g057" is added.
