Subject: [PATCH v3 0/4] Marvell PXA1908 power domains

Hello,

This series implements support for the power domains found in Marvell's
PXA1908 SoC. The domains control power for the graphics, video and image
processors along with the DSI PHY.

Changes in v3:
- Move driver back to pmdomain subsystem
- Instantiate using auxiliary bus
- Small fixes and refactors
- Rebase on v6.17-rc3
- Link to v2: https://lore.kernel.org/r/20250821-pxa1908-genpd-v2-0-eba413edd526@dujemihanovic.xyz

Changes in v2:
- Move driver to clk subsystem (domains are instantiated by clock
  driver)
- Drop power controller schema
- Drop RFC prefix
- Rebase on v6.17-rc2
- Link to v1: https://lore.kernel.org/r/20250806-pxa1908-genpd-v1-0-16409309fc72@dujemihanovic.xyz
