[PATCH v1 1/2] dt-bindings: soc: samsung: exynos-sysreg: add compatibles peric0/1 sysreg for Exynos990

[Denzeel Oliva]

Downstream from the Exynos990 kernel source it has more sysreg in
flexpmu, but for now only those two will be added.

[PATCH v1 2/2] arm64: dts: exynos990: Add the peric0/1 sysreg node

[Denzeel Oliva]

Add sysreg nodes for the PERIC0 and PERIC1 domains.
These system registers are used for peripheral configuration
and control in Exynos990.

Each sysreg node includes its base address, register size, and clock
dependencies.

Why is this a v1 while v1 was here:
https://lore.kernel.org/all/20250205222223.613-7-wachiturroxd150@gmail.com/

and both patches differ?

Where is the changelog?

Best regards,
Krzysztof
