1 * Cavium Interrupt Bus widget
2
3 Properties:
4 - compatible: "cavium,octeon-7130-cib"
5
6 Compatibility with cn70XX SoCs.
7
8 - interrupt-controller: This is an interrupt controller.
9
10 - reg: Two elements consisting of the addresses of the RAW and EN
11 registers of the CIB block
12
13 - cavium,max-bits: The index (zero based) of the highest numbered bit
14 in the CIB block.
15
16 - interrupts: The CIU line to which the CIB block is connected.
17
18 - #interrupt-cells: Must be <2>. The first cell is the bit within the
19 CIB. The second cell specifies the triggering semantics of the
20 line.
21
22 Example:
23
24 interrupt-controller@107000000e000 {
25 compatible = "cavium,octeon-7130-cib";
26 reg = <0x10700 0x0000e000 0x0 0x8>, /* RAW */
27 <0x10700 0x0000e100 0x0 0x8>; /* EN */
28 cavium,max-bits = <23>;
29
30 interrupt-controller;
31 interrupt-parent = <&ciu>;
32 interrupts = <1 24>;
33 /* Interrupts are specified by two parts:
34 * 1) Bit number in the CIB* registers
35 * 2) Triggering (1 - edge rising
36 * 2 - edge falling
37 * 4 - level active high
38 * 8 - level active low)
