1*4882a593SmuzhiyunOpen Multi-Processor Interrupt Controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun
5*4882a593Smuzhiyun- compatible : This should be "openrisc,ompic"
6*4882a593Smuzhiyun- reg : Specifies base physical address and size of the register space. The
7*4882a593Smuzhiyun  size is based on the number of cores the controller has been configured
8*4882a593Smuzhiyun  to handle, this should be set to 8 bytes per cpu core.
9*4882a593Smuzhiyun- interrupt-controller : Identifies the node as an interrupt controller.
10*4882a593Smuzhiyun- #interrupt-cells : This should be set to 0 as this will not be an irq
11*4882a593Smuzhiyun  parent.
12*4882a593Smuzhiyun- interrupts : Specifies the interrupt line to which the ompic is wired.
