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