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>;
|
|
};
