| 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>; | |
| }; |
