0001 * Central Interrupt Unit v3
0002
0003 Properties:
0004 - compatible: "cavium,octeon-7890-ciu3"
0005
0006 Compatibility with 78XX and 73XX SOCs.
0007
0008 - interrupt-controller: This is an interrupt controller.
0009
0010 - reg: The base address of the CIU's register bank.
0011
0012 - #interrupt-cells: Must be <2>. The first cell is source number.
0013 The second cell indicates the triggering semantics, and may have a
0014 value of either 4 for level semantics, or 1 for edge semantics.
0015
0016 Example:
0017 interrupt-controller@1010000000000 {
0018 compatible = "cavium,octeon-7890-ciu3";
0019 interrupt-controller;
0020 /* Interrupts are specified by two parts:
0021 * 1) Source number (20 significant bits)
0022 * 2) Trigger type: (4 == level, 1 == edge)
0023 */
0024 #address-cells = <0>;
0025 #interrupt-cells = <2>;
0026 reg = <0x10100 0x00000000 0x0 0xb0000000>;
0027 };
