Hi,

This patch series adds initial support for The Renesas RZ/G3S (R9A08G045{S33})
SoC. The RZ/G3S device is a general-purpose microprocessor with a
single-core Arm® Cortex®-A55 (1.1GHz) and a dual-core Arm® Cortex®-M33 (250MHz),
perfect for an IOT gateway controller.

This includes:
- SoC identification;
- clocks (core clocks, pin controller clock, serial interface, SD ch0
clock) and corresponding resets;
- minimal device tree for SoM and carrier boards.

With this series Linux can boot from eMMC or SD card. The eMMC and uSD
interface are multiplexed on the SoM; selection is made using a hardware
switch.

Patches are gouped as follows:
- 01 documents scif support;
- 02-05 contain fixes on clock drivers identified while adding RZ/G3S
support
- 06 clock cleanups identifies while adding support for RZ/G3S
- 07-13 clock changes needed by RZ/G3S
- 14-21 pinctrl changes needed by RZ/G3S
- 22-28 device tree support for RZ/G3S

Changes in v2:
- addressed review comments
- collected tags
- removed from series patches that were already integrated
- added patches:
- [PATCH v2 19/28] dt-bindings: pinctrl: renesas: set additionalProperties: false
- [PATCH v2 23/28] dt-bindings: arm: renesas: document RZ/G3S SMARC SoM
- [PATCH v2 26/28] dt-bindings: arm: renesas: document SMARC Carrier-II EVK
- please see individual patches for detailed changes
