+* Rockchip AXI PCIe Endpoint Controller DT description
+
+Required properties:
+- compatible: Should contain "rockchip,rk3399-pcie-ep"
+- reg: Two register ranges as listed in the reg-names property
+- reg-names: Must include the following names
+	- "apb-base"
+	- "mem-base"
+- clocks: Must contain an entry for each entry in clock-names.
+		See ../clocks/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+	- "aclk"
+	- "aclk-perf"
+	- "hclk"
+	- "pm"
+- resets: Must contain seven entries for each entry in reset-names.
+	   See ../reset/reset.txt for details.
+- reset-names: Must include the following names
+	- "core"
+	- "mgmt"
+	- "mgmt-sticky"
+	- "pipe"
+	- "pm"
+	- "aclk"
+	- "pclk"
+- pinctrl-names : The pin control state names
+- pinctrl-0: The "default" pinctrl state
+- phys: Must contain an phandle to a PHY for each entry in phy-names.
+- phy-names: Must include 4 entries for all 4 lanes even if some of
+  them won't be used for your cases. Entries are of the form "pcie-phy-N":
+  where N ranges from 0 to 3.
+  (see example below and you MUST also refer to ../phy/rockchip-pcie-phy.txt
+  for changing the #phy-cells of phy node to support it)
+- rockchip,max-outbound-regions: Maximum number of outbound regions
+
+Optional Property:
+- num-lanes: number of lanes to use
+- max-functions: Maximum number of functions that can be configured (default 1).
