| 2 | |
| 3 | Required 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 | |
| 14 | Example: |
| 15 | |
| 16 | ompic: interrupt-controller@98000000 { |
| 17 | compatible = "openrisc,ompic"; |
| 18 | reg = <0x98000000 16>; |
| 19 | interrupt-controller; |
| 20 | #interrupt-cells = <0>; |
| 21 | interrupts = <1>; |
| 22 | }; |
