description:
The Renesas SoCs of the RZ/G2L 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.

description:
The first cell contains the global GPIO port index, constructed using the
RZG2L_GPIO() helper macro in <dt-bindings/pinctrl/rzg2l-pinctrl.h> and the
second cell represents consumer flag as mentioned in ../gpio/gpio.txt
E.g. "RZG2L_GPIO(39, 1)" for P39_1.
