1 TI Keystone PCIe interface
3 Keystone PCI host Controller is based on the Synopsys DesignWare PCI
4 hardware version 3.65. It shares common functions with the PCIe DesignWare
5 core driver and inherits common properties defined in
6 Documentation/devicetree/bindings/pci/designware-pcie.txt
8 Please refer to Documentation/devicetree/bindings/pci/designware-pcie.txt
9 for the details of DesignWare DT bindings. Additional properties are
10 described here as well as properties that are not applicable.
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.
18 pcie_msi_intc : Interrupt controller device node for MSI IRQ chip
19 interrupt-cells: should be set to 1
20 interrupts: GIC interrupt lines connected to PCI MSI interrupt lines

52 phys: phandle to generic Keystone SerDes PHY for PCI
53 phy-names: name of the generic Keystone SerDes PHY for PCI
54 - If boot loader already does PCI link establishment, then phys and
55 phy-names shouldn't be present.
56 interrupts: platform interrupt for error interrupts.
58 DesignWare DT Properties not applicable for Keystone PCI
60 1. pcie_bus clock-names not used. Instead, a phandle to phys is used.
