This patch series adds the pin control and GPIO driver for the nuvoton ma35d1
ARMv8 SoC. It includes DT binding documentation, the ma35d1 pin control driver,
and device tree updates.

This pin control driver has been tested on the ma35d1 som board with Linux 6.7.

v3:
  - Update DTS and YAML files
    - Corrected the unit address of nodes gpioa ~ gpion.
    - Removed the invalid "pin-default" node.
    - Removed the phandle entry from "nuvoton,pins".
  - Update pinctrl driver
    - Fixed the Kconfig by using "depend on" instead of "if".
    - Removed unused #include of header files.
    - Utilized immutable irq_chip instead of dynamic irq_chip.
    - Replaced ma35_dt_free_map() with pinconf_generic_dt_free_map().
    - Implemented other minor fixes as suggested by the reviewer.

v2:
  - Update nuvoton,ma35d1-pinctrl.yaml
    - Update the 'nuvoton,pins' to follow the style of rockchip pinctrl approch.
    - Use power-source to indicate the pin voltage selection which follow the
      realtek pinctrl approch.
    - Instead of integer, use drive-strength-microamp to specify the real driving
      strength capability of IO pins.
  - Update ma35d1 pinctrl driver
    - Add I/O drive strength lookup table for translating device tree setting
      into control register.
  - Remove ma35d1-pinfunc.h which is unused after update definition of 'nuvoton,pins'.
