Minghuan Lian5e79cb22016-03-23 19:08:19 +08001* 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,1s1021a-msi"
8 "fsl,1s1043a-msi"
9- msi-controller: indicates that this is a PCIe MSI controller node
10- reg: physical base address of the controller and length of memory mapped.
11- interrupts: an interrupt to the parent interrupt controller.
12
13Optional properties:
14- interrupt-parent: the phandle 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,1s1043a-msi";
27 reg = <0x0 0x1571000 0x0 0x8>,
28 msi-controller;
29 interrupts = <0 116 0x4>;
30 };
