1OpenRISC 1000 Programmable Interrupt Controller
2
3Required properties:
4
5- compatible : should be "opencores,or1k-pic-level" for variants with
6 level triggered interrupt lines, "opencores,or1k-pic-edge" for variants with
7 edge triggered interrupt lines or "opencores,or1200-pic" for machines
8 with the non-spec compliant or1200 type implementation.
9
10 "opencores,or1k-pic" is also provided as an alias to "opencores,or1200-pic",
11 but this is only for backwards compatibility.
12
13- interrupt-controller : Identifies the node as an interrupt controller
14- #interrupt-cells : Specifies the number of cells needed to encode an
15 interrupt source. The value shall be 1.
16
17Example:
18
19intc: interrupt-controller {
20 compatible = "opencores,or1k-pic-level";
21 interrupt-controller;
22 #interrupt-cells = <1>;
23};
