1 * Central Interrupt Unit v3
2
3 Properties:
4 - compatible: "cavium,octeon-7890-ciu3"
5
6 Compatibility with 78XX and 73XX SOCs.
7
8 - interrupt-controller: This is an interrupt controller.
9
10 - reg: The base address of the CIU's register bank.
11
12 - #interrupt-cells: Must be <2>. The first cell is source number.
13 The second cell indicates the triggering semantics, and may have a
14 value of either 4 for level semantics, or 1 for edge semantics.
15
16 Example:
17 interrupt-controller@1010000000000 {
18 compatible = "cavium,octeon-7890-ciu3";
19 interrupt-controller;
20 /* Interrupts are specified by two parts:
21 * 1) Source number (20 significant bits)
22 * 2) Trigger type: (4 == level, 1 == edge)
23 */
24 #address-cells = <0>;
25 #interrupt-cells = <2>;
26 reg = <0x10100 0x00000000 0x0 0xb0000000>;
27 };
