1Open Multi-Processor Interrupt Controller
2
3Required properties:
4
5- compatible : This should be "openrisc,ompic"
6- reg : Specifies base physical address and size of the register space. The
7 size is based on the number of cores the controller has been configured
8 to handle, this should be set to 8 bytes per cpu core.
9- interrupt-controller : Identifies the node as an interrupt controller.
10- #interrupt-cells : This should be set to 0 as this will not be an irq
11 parent.
12- interrupts : Specifies the interrupt line to which the ompic is wired.

14Example:
15
16ompic: interrupt-controller@98000000 {
17 compatible = "openrisc,ompic";
18 reg = <0x98000000 16>;
19 interrupt-controller;
20 #interrupt-cells = <0>;
21 interrupts = <1>;
22};
