+* 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.
+
+Optional properties:
+- cdns,max-outbound-regions: Set to maximum number of outbound regions
+ (default 32).
+- max-functions: Maximum number of functions that can be configured (default 1).
+
+Example:
+
+pcie@fc000000 {
+ compatible = "cdns,cdns-pcie-ep";
+ reg = <0x0 0xfc000000 0x0 0x01000000>,
+ <0x0 0x80000000 0x0 0x40000000>;
+ reg-names = "reg", "mem";
+ cdns,max-outbound-regions = <16>;
+ max-functions = /bits/ 8 <8>;
+};
