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 16This interrupt controller hardware is a second level interrupt controller that 17is hooked to a parent interrupt controller: e.g: ARM GIC for ARM-based 18platforms. If interrupt-parent is not provided, the default parent interrupt 19controller will be used. 20Each PCIe node needs to have property msi-parent that points to 21MSI controller node 22 23Examples: 24 25 msi1: msi-controller@1571000 { 26 compatible = "fsl,ls1043a-msi"; 27 reg = <0x0 0x1571000 0x0 0x8>, 28 msi-controller; 29 interrupts = <0 116 0x4>; 30 };
