* Central Interrupt Unit v3
|
|
|
|
Properties:
|
|
- compatible: "cavium,octeon-7890-ciu3"
|
|
|
|
Compatibility with 78XX and 73XX SOCs.
|
|
|
|
- interrupt-controller: This is an interrupt controller.
|
|
|
|
- reg: The base address of the CIU's register bank.
|
|
|
|
- #interrupt-cells: Must be <2>. The first cell is source number.
|
|
The second cell indicates the triggering semantics, and may have a
|
|
value of either 4 for level semantics, or 1 for edge semantics.
|
|
|
|
Example:
|
|
interrupt-controller@1010000000000 {
|
|
compatible = "cavium,octeon-7890-ciu3";
|
|
interrupt-controller;
|
|
/* Interrupts are specified by two parts:
|
|
* 1) Source number (20 significant bits)
|
|
* 2) Trigger type: (4 == level, 1 == edge)
|
|
