* Freescale Layerscape SCFG PCIe MSI controller |
|
|
|
Required properties: |
|
|
|
- compatible: should be "fsl,<soc-name>-msi" to identify |
|
Layerscape PCIe MSI controller block such as: |
|
"fsl,ls1021a-msi" |
|
"fsl,ls1043a-msi" |
|
"fsl,ls1046a-msi" |
|
"fsl,ls1043a-v1.1-msi" |
|
"fsl,ls1012a-msi" |
|
- msi-controller: indicates that this is a PCIe MSI controller node |
|
- reg: physical base address of the controller and length of memory mapped. |
|
- interrupts: an interrupt to the parent interrupt controller. |
|
|
|
This interrupt controller hardware is a second level interrupt controller that |
|
is hooked to a parent interrupt controller: e.g: ARM GIC for ARM-based |
|
platforms. If interrupt-parent is not provided, the default parent interrupt |
|
controller will be used. |
|
Each PCIe node needs to have property msi-parent that points to |
|
MSI controller node |
|
|
|
Examples: |
|
|
|
msi1: msi-controller@1571000 { |
|
compatible = "fsl,ls1043a-msi"; |
|
reg = <0x0 0x1571000 0x0 0x8>, |
|
msi-controller; |
|
interrupts = <0 116 0x4>; |
|
};
