* Advanced Interrupt Controller (AIC)



Required properties:

- compatible: Should be "atmel,<chip>-aic"

  <chip> can be "at91rm9200", "sama5d2", "sama5d3" or "sama5d4"

- compatible: Should be:

    - "atmel,<chip>-aic" where  <chip> can be "at91rm9200", "sama5d2",

      "sama5d3" or "sama5d4"

    - "microchip,<chip>-aic" where <chip> can be "sam9x60"



- interrupt-controller: Identifies the node as an interrupt controller.

- #interrupt-cells: The number of cells to define the interrupts. It should be 3.

  The first cell is the IRQ number (aka "Peripheral IDentifier" on datasheet).
