1* Freescale Layerscape SCFG PCIe MSI controller
2
3Required properties:
4
5- compatible: should be "fsl,<soc-name>-msi" to identify
6	      Layerscape PCIe MSI controller block such as:
7              "fsl,ls1021a-msi"
8              "fsl,ls1043a-msi"
9              "fsl,ls1046a-msi"
10              "fsl,ls1043a-v1.1-msi"
11              "fsl,ls1012a-msi"
12- msi-controller: indicates that this is a PCIe MSI controller node
13- reg: physical base address of the controller and length of memory mapped.
14- interrupts: an interrupt to the parent interrupt controller.
15
16Optional properties:
17- interrupt-parent: the phandle to the parent interrupt controller.
18
19This interrupt controller hardware is a second level interrupt controller that
20is hooked to a parent interrupt controller: e.g: ARM GIC for ARM-based
21platforms. If interrupt-parent is not provided, the default parent interrupt
22controller will be used.
23Each PCIe node needs to have property msi-parent that points to
24MSI controller node

26Examples:
27
28	msi1: msi-controller@1571000 {
29		compatible = "fsl,ls1043a-msi";
30		reg = <0x0 0x1571000 0x0 0x8>,
31		msi-controller;
32		interrupts = <0 116 0x4>;
33	};
