- OpenRISC 1000 Programmable Interrupt Controller
- Required properties:
- - compatible : should be "opencores,or1k-pic-level" for variants with
- level triggered interrupt lines, "opencores,or1k-pic-edge" for variants with
- edge triggered interrupt lines or "opencores,or1200-pic" for machines
- with the non-spec compliant or1200 type implementation.
- "opencores,or1k-pic" is also provided as an alias to "opencores,or1200-pic",
- but this is only for backwards compatibility.
- - 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:
- intc: interrupt-controller {
- compatible = "opencores,or1k-pic-level";
- interrupt-controller;
- #interrupt-cells = <1>;
- };
