      Specifies respectively the interrupt number and flags as defined
      in include/dt-bindings/interrupt-controller/irq.h.
      Since all interrupts are active high, only IRQ_TYPE_LEVEL_HIGH
      and IRQ_TYPE_EDGE_RISING can be specified as type flags.
      The supported values for the interrupt number are:
