- Open Multi-Processor Interrupt Controller
- Required properties:
- - compatible : This should be "openrisc,ompic"
- - reg : Specifies base physical address and size of the register space. The
- size is based on the number of cores the controller has been configured
- to handle, this should be set to 8 bytes per cpu core.
- - interrupt-controller : Identifies the node as an interrupt controller.
- - #interrupt-cells : This should be set to 0 as this will not be an irq
- parent.
- - interrupts : Specifies the interrupt line to which the ompic is wired.
- Example:
- ompic: interrupt-controller@98000000 {
- compatible = "openrisc,ompic";
- reg = <0x98000000 16>;
- interrupt-controller;
- #interrupt-cells = <0>;
- interrupts = <1>;
- };
