1 * ARC-HS incore Interrupt Controller (Provided by cores implementing ARCv2 ISA)
5 - compatible: "snps,archs-intc"
6 - interrupt-controller: This is an interrupt controller.
7 - #interrupt-cells: Must be <1>.
9 Single Cell "interrupts" property of a device specifies the IRQ number
12 intc accessed via the special ARC AUX register interface, hence "reg" property
17 intc: interrupt-controller {
18 compatible = "snps,archs-intc";
20 #interrupt-cells = <1>;
21 interrupts = <16 17 18 19 20 21 22 23 24 25>;
