1* ARC700 incore Interrupt Controller
2
3  The core interrupt controller provides 32 prioritised interrupts (2 levels)
4  to ARC700 core.
5
6Properties:
7
8- compatible: "snps,arc700-intc"
9- interrupt-controller: This is an interrupt controller.
10- #interrupt-cells: Must be <1>.
11
12  Single Cell "interrupts" property of a device specifies the IRQ number
13  between 0 to 31
14
15  intc accessed via the special ARC AUX register interface, hence "reg" property
16  is not specified.

18Example:
19
20	intc: interrupt-controller {
21		compatible = "snps,arc700-intc";
22		interrupt-controller;
23		#interrupt-cells = <1>;
24	};
