- 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)
*/
#address-cells = <0>;
#interrupt-cells = <2>;
reg = <0x10100 0x00000000 0x0 0xb0000000>;
};
