[PATCH v2 0/5] arm64: dts: exynos2200: introduce serial busses, except spi

From: Ivaylo Ivanov

Hey, folks!

Before anything, this patchset only has binding dependencies, without
which it will have undocumented compatibles. They are the following:

[1] - https://lore.kernel.org/all/20250730072730.1882549-1-ivo.ivanov.ivanov1@xxxxxxxxx/

This patchset adds serial busses, implemented in usi, as well as serial_0
and serial_1 for exynos2200. It's missing spi, due to me having troubles
with reads when testing.

Best regards,
Ivaylo

Changes in v2:
- add a patch that switches address and size cells to 1 in /soc
- adjust all new nodes to define reg props with 2 cells in total instead of 4
