13description:
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.
