Tom Rini53633a82024-02-29 12:33:36 -05001* 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 };
