+Ethernet Node
+
+DESCRIPTION
+
+Ethernet Node has all the properties associated with PFE used by platforms to
+connect to PHY:
+
+PROPERTIES
+
+- compatible
+		Usage: required
+		Value type: <stringlist>
+		Definition: Must include "fsl,pfe-gemac-port"
+
+- reg
+		Usage: required
+		Value type: <prop-encoded-array>
+		Definition: A standard property.
+		Specifies the gemacid of the interface.
+
+- fsl,gemac-bus-id
+		Usage: required
+		Value type: <u32>
+		Definition: Must be present. Value should be the id of the bus
+		connected to gemac.
+
+- fsl,gemac-phy-id (deprecated binding)
+               Usage: required
+               Value type: <u32>
+               Definition: This binding shouldn't be used with new platforms.
+	       Must be present. Value should be the id of the phy
+               connected to gemac.
+
+- fsl,mdio-mux-val
+		Usage: required
+		Value type: <u32>
+		Definition: Must be present. Value can be either 0 or 2 or 3.
+		This value is used to configure the mux to enable mdio.
+

+		Usage: required
+		Value type: <string>
+		Definition: Must include "sgmii"
+
+- fsl,pfe-phy-if-flags (deprecated binding)
+               Usage: required
+               Value type: <u32>
+               Definition: This binding shouldn't be used with new platforms.
+               Must be present. Value should be 0 by default.
+               If there is not phy connected, this need to be 1.
+
+- phy-handle
+		Usage: optional
+		Value type: <phandle>
+		Definition: phandle to the PHY device connected to this device.
+
+- mdio : A required subnode which specifies the mdio bus in the PFE and used as
+a container for phy nodes according to ../phy.txt.
