+description:
+ The Renesas SoCs of the RZ/{G2L,V2L} alike series feature a combined Pin and
+ GPIO controller.
+ Pin multiplexing and GPIO configuration is performed on a per-pin basis.
+ Each port features up to 8 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.
