-* Advanced Interrupt Controller (AIC)
-
-Required properties:
-- compatible: Should be "atmel,<chip>-aic"
-  <chip> can be "at91rm9200" or "sama5d3"
-- interrupt-controller: Identifies the node as an interrupt controller.
-- interrupt-parent: For single AIC system, it is an empty property.
-- #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).
-  The second cell is used to specify flags:
-    bits[3:0] trigger type and level flags:
-      1 = low-to-high edge triggered.
-      2 = high-to-low edge triggered.
-      4 = active high level-sensitive.
-      8 = active low level-sensitive.
-      Valid combinations are 1, 2, 3, 4, 8.
-      Default flag for internal sources should be set to 4 (active high).
-  The third cell is used to specify the irq priority from 0 (lowest) to 7
-  (highest).
-- reg: Should contain AIC registers location and length
-- atmel,external-irqs: u32 array of external irqs.
