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. 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 }; 27
