+Hisilicon hip04 Ethernet Controller
+
+* Ethernet controller node
+
+Required properties:
+- compatible: should be "hisilicon,hip04-mac".
+- reg: address and length of the register set for the device.
+- interrupts: interrupt for the device.
+- port: ppe port number connected to the controller: range from 0 to 31.
+- speed: 100 (100M) or 1000 (1000M).
+- id: should be different and fe should be 0.
+
+Optional Properties:
+- phy-handle : the phandle to a PHY node
+
+
+* Ethernet ppe node: control rx & tx fifos of all ethernet controllers
+
+Required properties:
+- compatible: should be "hisilicon,hip04-ppebase".
+- reg: address and length of the register set for the node.
+
+
+* MDIO bus node:
+
+Required properties:
+
+- compatible: "hisilicon,hip04-mdio"
+- Inherets from MDIO bus node binding[1]
+[1] Documentation/devicetree/bindings/net/phy.txt
+
+Example:
+	mdio {
+		compatible = "hisilicon,hip04-mdio";

+

+
