| 2 | |
| 3 | Properties: |
| 4 | - compatible: "cavium,octeon-6880-ciu2" |
| 5 | |
| 6 | Compatibility with 68XX SOCs. |
| 7 | |
| 8 | - interrupt-controller: This is an interrupt controller. |
| 9 | |
| 10 | - reg: The base address of the CIU's register bank. |
| 11 | |
| 12 | - #interrupt-cells: Must be <2>. The first cell is the bank within |
| 13 | the CIU and may have a value between 0 and 63. The second cell is |
| 14 | the bit within the bank and may also have a value between 0 and 63. |
| 15 | |
| 16 | Example: |
| 17 | interrupt-controller@1070100000000 { |
| 18 | compatible = "cavium,octeon-6880-ciu2"; |
| 19 | interrupt-controller; |
| 20 | /* Interrupts are specified by two parts: |
| 21 | * 1) Controller register (0..63) |
| 22 | * 2) Bit within the register (0..63) |
