Hi,

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

Series is split as follows:
- patch 01/12      - add clock, reset and PM domain support
- patch 02-03/12   - add some cleanups on RIIC driver
- patch 05/12      - enable runtime autosuspend support on the RIIC driver
- patch 06/12      - add suspend to RAM support on the RIIC driver
- patch 07/12      - prepares for the addition of fast mode plus
- patch 08/12      - updates the I2C documentation for the RZ/G3S SoC
- patch 09/12      - add fast mode plus support on the RIIC driver
- patches 10-12/12 - device tree support

Thank you,
Claudiu Beznea

Changes in v2:
- change the i2c clock names to match the documentation
- update commit description for patch "i2c: riic: Use temporary
  variable for struct device"
- addressed review comments
- dropped renesas,riic-no-fast-mode-plus DT property and associated code
