* 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).
