+* ARC700 incore Interrupt Controller
+
+ The core interrupt controller provides 32 prioritised interrupts (2 levels)
+ to ARC700 core.
+
+Properties:
+
+- compatible: "snps,arc700-intc"
+- interrupt-controller: This is an interrupt controller.
+- #interrupt-cells: Must be <1>.
+
+ Single Cell "interrupts" property of a device specifies the IRQ number
+ between 0 to 31
+
+ intc accessed via the special ARC AUX register interface, hence "reg" property
+ is not specified.
+
+Example:
+
+ intc: interrupt-controller {
+ compatible = "snps,arc700-intc";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ };
