| 1 | * Cortina Systems Gemini interrupt controller | ||
| 2 | |||
| 3 | This interrupt controller is found on the Gemini SoCs. | ||
| 4 | |||
| 5 | Required properties: | ||
| 6 | - compatible: must be "cortina,gemini-interrupt-controller" | ||
| 7 | - reg: The register bank for the interrupt controller. | ||
| 8 | - interrupt-controller: Identifies the node as an interrupt controller | ||
| 9 | - #interrupt-cells: The number of cells to define the interrupts. | ||
| 10 | Must be 2 as the controller can specify level or rising edge | ||
| 11 | IRQs. The bindings follows the standard binding for controllers | ||
| 12 | with two cells specified in | ||
| 13 | interrupt-controller/interrupts.txt | ||
| 14 | |||
| 15 | Example: | ||
| 16 | |||
| 17 | interrupt-controller@48000000 { | ||
| 18 | compatible = "cortina,gemini-interrupt-controller"; | ||
| 19 | reg = <0x48000000 0x1000>; | ||
| 20 | interrupt-controller; | ||
| 21 | #interrupt-cells = <2>; | ||
