dt-bindings: i2c: renesas,riic: Document R9A09G057 support
Document support for the I2C Bus Interface (RIIC) available in the
Renesas RZ/V2H(P) (R9A09G057) SoC.
The RIIC interface in the Renesas RZ/V2H(P) differs from RZ/A in a
couple of ways:
- Register offsets for the RZ/V2H(P) SoC differ from those of the
RZ/A SoC.
- RZ/V2H register access is limited to 8-bit, whereas RZ/A supports
8/16/32-bit.
- RZ/V2H has bit differences in the slave address register.
To accommodate these differences, a new compatible string
"renesas,riic-r9a09g057" is added.
