+* 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,1s1021a-msi"
+ "fsl,1s1043a-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.
+Optional properties:
+- interrupt-parent: the phandle 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
+ msi1: msi-controller@1571000 {
+ compatible = "fsl,1s1043a-msi";
+ reg = <0x0 0x1571000 0x0 0x8>,
+ msi-controller;
+ interrupts = <0 116 0x4>;
+ };
