13 description:
14 The Renesas SoCs of the RZ/{G2L,V2L} alike series feature a combined Pin and
15 GPIO controller.
16 Pin multiplexing and GPIO configuration is performed on a per-pin basis.
17 Each port features up to 8 pins, each of them configurable for GPIO function
18 (port mode) or in alternate function mode.
19 Up to 8 different alternate function modes exist for each single pin.
