| 2 | |
| 3 | Required properties: |
| 4 | |
| 5 | - compatible: Should be "jcore,aic1" for the (obsolete) first-generation aic |
| 6 | with 8 interrupt lines with programmable priorities, or "jcore,aic2" for |
| 7 | the "aic2" core with 64 interrupts. |
| 8 | |
| 9 | - reg: Memory region(s) for configuration. For SMP, there should be one |
| 10 | region per cpu, indexed by the sequential, zero-based hardware cpu |
| 11 | number. |
| 12 | |
| 13 | - interrupt-controller: Identifies the node as an interrupt controller |
| 14 | |
| 15 | - #interrupt-cells: Specifies the number of cells needed to encode an |
| 16 | interrupt source. The value shall be 1. |
| 17 | |
| 18 | |
| 19 | Example: |
| 20 | |
| 21 | aic: interrupt-controller@200 { |
| 22 | compatible = "jcore,aic2"; |
| 23 | reg = < 0x200 0x30 0x500 0x30 >; |
| 24 | interrupt-controller; |
| 25 | #interrupt-cells = <1>; |
| 26 | }; |
