Subject: [PATCH v4 0/6] Support RK3528 variant of Rockchip naneng-combphy

Rockchip RK3528 ships a naneng-combphy that operates in either PCIe or
USB 3.0 mode. It has a similar control logic to previous generations of
naneng-combphy but an apparently different register layout.

This series prepares phy-rockchip-naneng-combphy.c for variants with a
different register layout and add RK3528 support.

Testing is done on both Radxa E20C and Radxa Rock 2A with downstream
devicetree changes, both USB 3 and PCIe modes are verified with mainline
driver and achives a reasonable link speed.

This series depends on v2 of patch "arm64: dts: rockchip: convert rk3528
power-domains to dt-binding constants"[1] to build.

Changed from v3
- Add a dt-binding patch to allow power-domains property when describing
  Rockchip naneng combphys
- devicetree patch
  - Break down long lines
  - Sort properties to keep the style consistent
  - Add power-domains property to the combphy node
- Link to v3: https://lore.kernel.org/linux-rockchip/20250519161612.14261-1-ziyao@disroot.org/
Changed from v2
- phy binding patch
  - Fix format issue
  - drop review tags
- Link to v2: https://lore.kernel.org/all/20250509004121.36058-2-ziyao@disroot.

Changed from v1
- Collect review tags
- Restyle RK3528 register definitions in the combphy driver
- Drop unused include of phy.h in SoC devicetree
