Subject: [PATCH 08/12] dt-bindings: i2c: renesas,riic: Document the R9A08G045 support

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Document the Renesas RZ/G3S (R9A08G045) RIIC IP. This is compatible with
the version available on Renesas RZ/V2H (R9A09G075). Most of the IP
variants that the RIIC driver is working with supports fast mode plus.
However, it happens that on the same SoC to have IP instatiations that
support fast mode plus as well as IP instantiation that doesn't support
it. For this, introduced the renesas,riic-no-fast-mode-plus property.
