* Cavium Interrupt Bus widget |
|
|
|
Properties: |
|
- compatible: "cavium,octeon-7130-cib" |
|
|
|
Compatibility with cn70XX SoCs. |
|
|
|
- interrupt-controller: This is an interrupt controller. |
|
|
|
- reg: Two elements consisting of the addresses of the RAW and EN |
|
registers of the CIB block |
|
|
|
- cavium,max-bits: The index (zero based) of the highest numbered bit |
|
in the CIB block. |
|
|
|
- interrupts: The CIU line to which the CIB block is connected. |
|
|
|
- #interrupt-cells: Must be <2>. The first cell is the bit within the |
|
CIB. The second cell specifies the triggering semantics of the |
|
line. |
|
|
|
Example: |
|
|
|
interrupt-controller@107000000e000 { |
|
compatible = "cavium,octeon-7130-cib"; |
|
reg = <0x10700 0x0000e000 0x0 0x8>, /* RAW */ |
|
<0x10700 0x0000e100 0x0 0x8>; /* EN */ |
|
cavium,max-bits = <23>; |
|
|
|
interrupt-controller; |
|
interrupt-parent = <&ciu>; |
|
interrupts = <1 24>; |
|
/* Interrupts are specified by two parts: |
|
* 1) Bit number in the CIB* registers |
|
* 2) Triggering (1 - edge rising |
|
* 2 - edge falling |
|
* 4 - level active high |
|
* 8 - level active low) |
