+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-handle: <phandle port channel>
+ phandle, specifies a reference to the syscon ppe node
+ port, port number connected to the controller
+ channel, recv channel start from channel * number (RX_DESC_NUM)
+- phy-mode: see ethernet.txt [1].
+
+Optional properties:
+- phy-handle: see ethernet.txt [1].
+
+[1] Documentation/devicetree/bindings/net/ethernet.txt
+
+
+* Ethernet ppe node:
+Control rx & tx fifos of all ethernet controllers.
+Have 2048 recv channels shared by all ethernet controllers, only if no overlap.
+Each controller's recv channel start from channel * number (RX_DESC_NUM).
+
+Required properties:
+- compatible: "hisilicon,hip04-ppe", "syscon".
+- reg: address and length of the register set for the device.
+
+
+* MDIO bus node:
+
+Required properties:
+
+- compatible: should be "hisilicon,hip04-mdio".
+- Inherits from MDIO bus node binding [2]
+[2] Documentation/devicetree/bindings/net/phy.txt
+
+Example:
+ mdio {
+ compatible = "hisilicon,hip04-mdio";
+ reg = <0x28f1000 0x1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ phy0: ethernet-phy@0 {
