1Sigma Designs SMP86xx/SMP87xx secondary interrupt controller
2
3Required properties:
4- compatible: should be "sigma,smp8642-intc"
5- reg: physical address of MMIO region
6- ranges: address space mapping of child nodes
7- interrupt-parent: phandle of parent interrupt controller
8- interrupt-controller: boolean
9- #address-cells: should be <1>
10- #size-cells: should be <1>
11
12One child node per control block with properties:
13- reg: address of registers for this control block
14- interrupt-controller: boolean
15- #interrupt-cells: should be <2>, interrupt index and flags per interrupts.txt
16- interrupts: interrupt spec of primary interrupt controller

20interrupt-controller@6e000 {
21 compatible = "sigma,smp8642-intc";
22 reg = <0x6e000 0x400>;
23 ranges = <0x0 0x6e000 0x400>;
24 interrupt-parent = <&gic>;
25 interrupt-controller;
26 #address-cells = <1>;
27 #size-cells = <1>;
28
29 irq0: interrupt-controller@0 {
30 reg = <0x000 0x100>;
31 interrupt-controller;
32 #interrupt-cells = <2>;
33 interrupts = <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>;
34 };
35
36 irq1: interrupt-controller@100 {
37 reg = <0x100 0x100>;
38 interrupt-controller;
39 #interrupt-cells = <2>;
40 interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
41 };
42
43 irq2: interrupt-controller@300 {

45 interrupt-controller;
46 #interrupt-cells = <2>;
47 interrupts = <GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>;
