3 Keystone PCI host Controller is based on Designware PCI h/w version 3.65.
4 It shares common functions with PCIe Designware core driver and inherit
5 common properties defined in
6 Documentation/devicetree/bindings/pci/designware-pci.txt
7
8 Please refer to Documentation/devicetree/bindings/pci/designware-pci.txt
9 for the details of Designware DT bindings.  Additional properties are
10 described here as well as properties that are not applicable.
11
12 Required Properties:-
13
14 compatibility: "ti,keystone-pcie"
15 reg:    index 1 is the base address and length of DW application registers.
16         index 2 is the base address and length of PCI device ID register.
17
18 pcie_msi_intc : Interrupt controller device node for MSI IRQ chip
19         interrupt-cells: should be set to 1
20         interrupt-parent: Parent interrupt controller phandle
21         interrupts: GIC interrupt lines connected to PCI MSI interrupt lines
22
23  Example:
24         pcie_msi_intc: msi-interrupt-controller {
25                         interrupt-controller;
26                         #interrupt-cells = <1>;
27                         interrupt-parent = <&gic>;
28                         interrupts = <GIC_SPI 30 IRQ_TYPE_EDGE_RISING>,
29                                         <GIC_SPI 31 IRQ_TYPE_EDGE_RISING>,
30                                         <GIC_SPI 32 IRQ_TYPE_EDGE_RISING>,
31                                         <GIC_SPI 33 IRQ_TYPE_EDGE_RISING>,
32                                         <GIC_SPI 34 IRQ_TYPE_EDGE_RISING>,
33                                         <GIC_SPI 35 IRQ_TYPE_EDGE_RISING>,
34                                         <GIC_SPI 36 IRQ_TYPE_EDGE_RISING>,
35                                         <GIC_SPI 37 IRQ_TYPE_EDGE_RISING>;
36         };
37
38 pcie_intc: Interrupt controller device node for Legacy IRQ chip
39         interrupt-cells: should be set to 1
40         interrupt-parent: Parent interrupt controller phandle
41         interrupts: GIC interrupt lines connected to PCI Legacy interrupt lines
42
43  Example:
44         pcie_intc: legacy-interrupt-controller {
45                 interrupt-controller;
46                 #interrupt-cells = <1>;
47                 interrupt-parent = <&gic>;
48                 interrupts = <GIC_SPI 26 IRQ_TYPE_EDGE_RISING>,
49                         <GIC_SPI 27 IRQ_TYPE_EDGE_RISING>,
50                         <GIC_SPI 28 IRQ_TYPE_EDGE_RISING>,
51                         <GIC_SPI 29 IRQ_TYPE_EDGE_RISING>;
52         };
53
54 Optional properties:-
55         phys: phandle to Generic Keystone SerDes phy for PCI
56         phy-names: name of the Generic Keystine SerDes phy for PCI
57           - If boot loader already does PCI link establishment, then phys and
58             phy-names shouldn't be present.
59
60 Designware DT Properties not applicable for Keystone PCI
61
62 1. pcie_bus clock-names not used.  Instead, a phandle to phys is used.
