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.

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'.
