1Loongson ls1x Interrupt Controller
2
3Required properties:
4
5- compatible : should be "loongson,ls1x-intc". Valid strings are:
6
7- reg : Specifies base physical address and size of the registers.
8- interrupt-controller : Identifies the node as an interrupt controller
9- #interrupt-cells : Specifies the number of cells needed to encode an
10 interrupt source. The value shall be 2.
11- interrupts : Specifies the CPU interrupt the controller is connected to.

13Example:
14
15intc: interrupt-controller@1fd01040 {
16 compatible = "loongson,ls1x-intc";
17 reg = <0x1fd01040 0x18>;
18
19 interrupt-controller;
20 #interrupt-cells = <2>;
21
22 interrupt-parent = <&cpu_intc>;
23 interrupts = <2>;
24};
