    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 is used to specify the flag.

      E.g. "interrupts = <RZG2L_GPIO(43, 0) IRQ_TYPE_EDGE_FALLING>;" if P43_0 is

      being used as an interrupt.
