title: Renesas RZ/G2L (and alike SoC's) Interrupt Controller (IA55)

description: |
  IA55 performs various interrupt controls including synchronization for the external
  interrupts of NMI, IRQ, and GPIOINT and the interrupts of the built-in peripheral
  interrupts output by each IP. And it notifies the interrupt to the GIC
    - IRQ sense select for 8 external interrupts, mapped to 8 GIC SPI interrupts
    - GPIO pins used as external interrupt input pins, mapped to 32 GIC SPI interrupts
    - NMI edge select (NMI is not treated as NMI exception and supports fall edge and
      stand-up edge detection interrupts)
