+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";
+ reg = <0x28f1000 0x1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ phy0: ethernet-phy at 0 {
+ reg = <0>;
+ marvell,reg-init = <18 0x14 0 0x8001>;
+ device_type = "ethernet-phy";
+ };
+
+ phy1: ethernet-phy at 1 {
+ reg = <1>;
+ marvell,reg-init = <18 0x14 0 0x8001>;
+ device_type = "ethernet-phy";
+ };
+ };
+
+ ppebase: ppebase at 28c0000 {
+ compatible = "hisilicon,hip04-ppebase";
+ reg = <0x28c0000 0x10000>;
+ };
+
+ fe: ethernet at 28b0000 {
+ compatible = "hisilicon,hip04-mac";
+ reg = <0x28b0000 0x10000>;
+ interrupts = <0 413 4>;
+ port = <31>;
+ speed = <100>;

+ };

+ ge0: ethernet at 2800000 {
