+J-Core Advanced Interrupt Controller
+
+Required properties:
+
+- compatible: Should be "jcore,aic1" for the (obsolete) first-generation aic
+  with 8 interrupt lines with programmable priorities, or "jcore,aic2" for
+  the "aic2" core with 64 interrupts.
+
+- reg: Memory region(s) for configuration. For SMP, there should be one
+  region per cpu, indexed by the sequential, zero-based hardware cpu
+  number.
+
+- interrupt-controller: Identifies the node as an interrupt controller
+
+- #interrupt-cells: Specifies the number of cells needed to encode an
+  interrupt source. The value shall be 1.
+
+
+Example:
+
+aic: interrupt-controller@200 {
+	compatible = "jcore,aic2";
+	reg = < 0x200 0x30 0x500 0x30 >;
+	interrupt-controller;
+	#interrupt-cells = <1>;
+};
