Hi,

Series adds I2C support for the Renesas RZ/G3S SoC.

Series is split as follows:
- patch 01-03/12 - add some cleanups on RIIC driver
- patch 04/12 - enable runtime autosuspend support on the RIIC driver
- patch 05/12 - add suspend to RAM support on the RIIC driver
- patch 06/12 - prepares for the addition of fast mode plus
- patch 07/12 - updates the I2C documentation for the RZ/G3S SoC
- patch 08/12 - add fast mode plus support on the RIIC driver
- patches 09-11/11 - device tree support

Thank you,
Claudiu Beznea

Changes in v3:
- dropped patch "clk: renesas: r9a08g045: Add clock, reset and power
