Subject: [PATCH 0/6] Add RIIC support for RZ/T2H and RZ/N2H SoCs

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

Hi All,

This patch series adds support for I2C Bus Interface (RIIC) found on
the Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs. The RIIC
IP on these SoCs is similar to that on the RZ/V2H(P) SoC but has some
differences in interrupt handling and does not require resets.

Cheers,
Prabhakar
