     * 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>;
            };
