Kernel-4.18.0-80.el8_ciu3

  • 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>;
};
