* 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>;

|
|
/* 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)
