+AM654 PCIe Endpoint
+===================
+
+Required Properties:-
+
+compatibility: Should be "ti,am654-pcie-ep" for EP on AM654x SoC
+reg: Four register ranges as listed in the reg-names property
+reg-names: "dbics" for the DesignWare PCIe registers, "app" for the
+ TI specific application registers, "atu" for the
+ Address Translation Unit configuration registers and
+ "addr_space" used to map remote RC address space
+num-ib-windows: As specified in
+ Documentation/devicetree/bindings/pci/designware-pcie.txt
+num-ob-windows: As specified in
+ Documentation/devicetree/bindings/pci/designware-pcie.txt
+num-lanes: As specified in
+ Documentation/devicetree/bindings/pci/designware-pcie.txt
+power-domains: As documented by the generic PM domain bindings in
+ Documentation/devicetree/bindings/power/power_domain.txt.
+ti,syscon-pcie-mode: phandle to the device control module required to configure
+ PCI in either RC mode or EP mode.
+
+Optional properties:-
+
+phys: list of PHY specifiers (used by generic PHY framework)
+phy-names: must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the
+ number of lanes as specified in *num-lanes* property.
+("phys" and "phy-names" DT bindings are specified in
+Documentation/devicetree/bindings/phy/phy-bindings.txt)
+interrupts: platform interrupt for error interrupts.
