+* Cadence PCIe endpoint controller
+
+Required properties:
+- compatible: Should contain "cdns,cdns-pcie-ep" to identify the IP used.
+- reg: Should contain the controller register base address and AXI interface
+  region base address respectively.
+- reg-names: Must be "reg" and "mem" respectively.
+- cdns,max-outbound-regions: Set to maximum number of outbound regions
+
+Optional properties:
+- max-functions: Maximum number of functions that can be configured (default 1).
+- phys: From PHY bindings: List of Generic PHY phandles. One per lane if more
+  than one in the list.  If only one PHY listed it must manage all lanes. 
+- phy-names:  List of names to identify the PHY.
+
+Example:
+

+	compatible = "cdns,cdns-pcie-ep";

+	reg-names = "reg", "mem";
+	cdns,max-outbound-regions = <16>;
+	max-functions = /bits/ 8 <8>;
+	phys = <&ep_phy0 &ep_phy1>;
+	phy-names = "pcie-lane0","pcie-lane1";
