Subject: [PATCH v3 0/7] pinctrl: rockchip: Add RK3506 and RV1126B pinctrl and RMIO support

This series adds pinctrl support for the Rockchip RK3506 and RV1126B SoC,
and adds support for RMIO (Rockchip Matrix I/O).

The series includes:
- RK3506 pinctrl driver implementation
- RV1126B pinctrl driver implementation
- RMIO controller binding and driver support
- GPIO driver update to support new version GPIO

Note on grouping:
The RV1126B support patches are included in this series because the RV1126B
pinctrl driver implementation depends on the PIN_BANK_IOMUX_FLAGS_OFFSET_DRV_FLAGS
macro, which is introduced in the RK3506 support patches. Splitting these
patches into separate series would break the build for RV1126B if applied
independently.

Changes in v3:
- Drop already merged patches (rk3506 basic support).
- Remove unhelpful mappings in rockchip,rk3506-rmio.h
- Improve YAML schema: fix constraints and examples for RMIO.

Changes in v2:
- Added RV1126B pinctrl support (patches 3 and 4)
- Updated GPIO driver to support new version GPIO (patch 5)
- Added header file for RK3506 RMIO (patch 6)
- RMIO is now implemented as a separate pinctrl device (patches 7, 8)

Ye Zhang (7):
  pinctrl: rockchip: Add rk3506 pinctrl support
  dt-bindings: pinctrl: Add rv1126b pinctrl support
