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>;
};
