Sigma Designs SMP86xx/SMP87xx secondary interrupt controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: should be "sigma,smp8642-intc"
|
||
|
|
- reg: physical address of MMIO region
|
||
|
|
- ranges: address space mapping of child nodes
|
||
|
|
- interrupt-parent: phandle of parent interrupt controller
|
||
|
|
- interrupt-controller: boolean
|
||
|
|
- #address-cells: should be <1>
|
||
|
|
- #size-cells: should be <1>
|
||
|
|
|
||
|
|
One child node per control block with properties:
|
||
|
|
- reg: address of registers for this control block
|
||
|
|
- interrupt-controller: boolean
|
||
|
|
- #interrupt-cells: should be <2>, interrupt index and flags per interrupts.txt
|
||
|
|
- interrupts: interrupt spec of primary interrupt controller
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
interrupt-controller@6e000 {
