+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>;
+};
