0001 OpenRISC 1000 Programmable Interrupt Controller
0002
0003 Required properties:
0004
0005 - compatible : should be "opencores,or1k-pic-level" for variants with
0006 level triggered interrupt lines, "opencores,or1k-pic-edge" for variants with
0007 edge triggered interrupt lines or "opencores,or1200-pic" for machines
0008 with the non-spec compliant or1200 type implementation.
0009
0010 "opencores,or1k-pic" is also provided as an alias to "opencores,or1200-pic",
0011 but this is only for backwards compatibility.
0012
0013 - interrupt-controller : Identifies the node as an interrupt controller
0014 - #interrupt-cells : Specifies the number of cells needed to encode an
0015 interrupt source. The value shall be 1.
0016
0017 Example:
0018
0019 intc: interrupt-controller {
0020 compatible = "opencores,or1k-pic-level";
0021 interrupt-controller;
0022 #interrupt-cells = <1>;
0023 };
