This series adds support for the Phytium platform GPIO controller.

It includes:
- devicetree binding for "phytium,gpio" and vendor prefix registration
- core and platform GPIO driver support
- MAINTAINERS entry

This submission intentionally covers only the platform GPIO path.
Phytium PCI GPIO and SGPIO support are not included in this series.

Validation:
- dt_binding_check passed for Documentation/devicetree/bindings/gpio/phytium,gpio.yaml
- build tested with ARCH=arm64 cross compile
- runtime tested on a Phytium arm64 board with DT boot

  dt-bindings: gpio: add Phytium GPIO controller
  gpio: add support for Phytium platform GPIO controller
  MAINTAINERS: add entry for Phytium platform GPIO driver

I get cover letter detached from the patches (in terms of email thread).
Please, check how you prepare patches.
