+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 for configuration.
+
+- 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.
+
+Optional properties:
+
+- cpu-offset : For SMP, the offset to the per-cpu memory region for
+ configuration, to be scaled by the cpu number.
+
+
+Example:
+
+aic: interrupt-controller@200 {
+ compatible = "jcore,aic2";
+ reg = < 0x200 0x10 >;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+};
