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. 13 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}; 23
