  13 description:
  14   The Renesas RZ/V2M SoC features a combined Pin and GPIO controller.
  15   Pin multiplexing and GPIO configuration is performed on a per-pin basis.
  16   Each port features up to 16 pins, each of them configurable for GPIO function
  17   (port mode) or in alternate function mode.
  18   Up to 8 different alternate function modes exist for each single pin.
