[PATCH 0/5] Add watchdog and USB nodes for the Exynos990 SoC

[Igor Belwon]

Hi all!

This series adds the nodes to enable the watchdog and USB support for
the Exynos990 SoC.

The watchdog consists of two clusters (cl0 and cl2). Unsure why Samsung has
skipped cl1 on this SoC. Both are enabled and working - tested on a
device from the -x1s family.

The USB controller of this SoC supports full-speed, high-speed and
super-speed operation modes. Due to my inability to get any of my
Exynos990 devices to enumerate as super-speed (even under the vendor
kernels) only the UTMI+ setup is done - as such, only the high-speed
mode is enabled. Dummy regulators are used in place of PMIC provided
ones until we implement PMIC.

This series depends on the following series:
- Watchdog commit: https://lore.kernel.org/all/20250217-exynos990-wdt-v2-0-3eb4fbc113f4@mentallysanemainliners.org
- USB commits:
	- https://lore.kernel.org/all/20250217-exynos990-bindings-usb3-v2-1-3b3f0809f4fb@mentallysanemainliners.org/
