Subject: [PATCH 0/7] Add support for the Axis ARTPEC-9 SoC

Add basic support for the Axis ARTPEC-9 SoC which contains
6-core Cortex-A55 CPU and other several IPs. This SoC is an
Axis-designed chipset used in surveillance camera products.

This ARTPEC-9 SoC has a variety of Samsung-specific IP blocks and
Axis-specific IP blocks and SoC is manufactured by Samsung Foundry.

This patch series includes below changes:
- CMU (Clock Management Unit) driver and its bindings (patch #1 to #3)
- PMU bindings (patch #4)
- Basic Device Tree for ARTPEC-9 SoC and boards (patch #5 to #7)

The patch series has been tested on the ARTPEC-9 EVB with
Linux Samsung SoC tree (for-next branch) and intended
to be merged via the `arm-soc` tree.

NOTE: This patch series is dependent on following floating patches:
1. https://lore.kernel.org/all/20250917070004.87872-1-ravi.patel@samsung.com/T/#t
2. https://lore.kernel.org/all/20250917071342.5637-1-ravi.patel@samsung.com/T/#u
