1 J-Core Advanced Interrupt Controller
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.

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>;
