0001 * Freescale Layerscape SCFG PCIe MSI controller
0002
0003 Required properties:
0004
0005 - compatible: should be "fsl,<soc-name>-msi" to identify
0006 Layerscape PCIe MSI controller block such as:
0007 "fsl,ls1021a-msi"
0008 "fsl,ls1043a-msi"
0009 "fsl,ls1046a-msi"
0010 "fsl,ls1043a-v1.1-msi"
0011 "fsl,ls1012a-msi"
0012 - msi-controller: indicates that this is a PCIe MSI controller node
0013 - reg: physical base address of the controller and length of memory mapped.
0014 - interrupts: an interrupt to the parent interrupt controller.
0015
0016 This interrupt controller hardware is a second level interrupt controller that
0017 is hooked to a parent interrupt controller: e.g: ARM GIC for ARM-based
0018 platforms. If interrupt-parent is not provided, the default parent interrupt
0019 controller will be used.
0020 Each PCIe node needs to have property msi-parent that points to
0021 MSI controller node
0022
0023 Examples:
0024
0025 msi1: msi-controller@1571000 {
0026 compatible = "fsl,ls1043a-msi";
0027 reg = <0x0 0x1571000 0x0 0x8>,
0028 msi-controller;
0029 interrupts = <0 116 0x4>;
0030 };
