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>;
|
};
