J-Core Advanced Interrupt Controller Required properties: - compatible: Should be "jcore,aic1" for the (obsolete) first-generation aic with 8 interrupt lines with programmable priorities, or "jcore,aic2" for the "aic2" core with 64 interrupts. - reg: Memory region(s) for configuration. For SMP, there should be one region per cpu, indexed by the sequential, zero-based hardware cpu number. - interrupt-controller: Identifies the node as an interrupt controller - #interrupt-cells: Specifies the number of cells needed to encode an interrupt source. The value shall be 1. Example: aic: interrupt-controller@200 { compatible = "jcore,aic2"; reg = < 0x200 0x30 0x500 0x30 >; interrupt-controller; #interrupt-cells = <1>; };
