Subject: [PATCH v3 0/4] Add new Renesas RZ/G3S SoC and RZ/G3S SMARC EVK

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

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;
- 02-04	clock changes needed by RZ/G3S

Changes in v3:
- remove from series patches that were already integrated
- addressed review comments
- please see individual patches for detailed changes

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

Claudiu Beznea (4):
  dt-bindings: serial: renesas,scif: document r9a08g045 support
  clk: renesas: rzg2l: refactor sd mux driver
  clk: renesas: rzg2l: add a divider clock for RZ/G3S
  clk: renesas: add minimal boot support for RZ/G3S SoC
