1Cirrus Logic CLPS711X Interrupt Controller
2
3Required properties:
4
5- compatible: Should be "cirrus,ep7209-intc".
6- reg: Specifies base physical address of the registers set.
7- interrupt-controller: Identifies the node as an interrupt controller.
8- #interrupt-cells: Specifies the number of cells needed to encode an
9  interrupt source. The value shall be 1.

11The interrupt sources are as follows:

36	intc: interrupt-controller {
37		compatible = "cirrus,ep7312-intc", "cirrus,ep7209-intc";
38		reg = <0x80000000 0x4000>;
39		interrupt-controller;
40		#interrupt-cells = <1>;
41	};
