Hi folks,

This is v2 of my A523 power controllers series.

Changes since v1:
- Re-order compatible string entries
- Fix name of header file to match compatible string
- Link to v1:
  https://lore.kernel.org/all/20250627152918.2606728-1-wens@kernel.org/

This series adds the power controllers found in the Allwinner A523
family of SoCs. There are two power controllers. One is the same type
as those found in the D1 SoC, just with a different number of valid
power domains. The second is (I assume) a unit based on ARM's PCK-600
power controller. Some of the registers and values match up, but there
are extra registers for delay controls in the PCK-600's reserved
register range.

Patch 1 adds new compatible string entries for both of these
controllers.

Patch 2 adds support for the A523 PPU to the existing D1 PPU driver.

Patch 3 adds a new driver of the PCK-600 unit in the A523 SoC.

Patch 4 adds device nodes for both of these controllers.


Please have a look. The power controllers are critical for enabling more
peripherals, such as display output, camera input, video codecs, the NPU,
and a second DWMAC-compatible ethernet interface.


Thanks
ChenYu

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250709 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
