++ Value type: <stringlist>
++ Definition: Following strings are defined for the 3 interrupts.
++ "pfe_hif" - HIF interrupt
++ "pfe_hif_nocpy" - HIF NO COPY interrupt
++ "pfe_wol" - Wake On LAN interrupt
++
++- memory-region
++ Usage: required
++ Value type: <phandle>

++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
++ Usage: required
++ Value type: <u32>
++ Definition: 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.
++
++- phy-mode
++ Usage: required
++ Value type: <string>
++ Definition: Must include "sgmii"
++
++- fsl,pfe-phy-if-flags
++ Usage: required
++ Value type: <u32>
++ Definition: Must be present. Value should be 0 by default.
++ If there is not phy connected, this need to be 1.
++
++- mdio
++ optional subnode that specifies the mdio bus. This has reg
++ property which is used to enable/disable the mdio bus.
++
++EXAMPLE
++
++ethernet@0 {
++ compatible = "fsl,pfe-gemac-port";
++ #address-cells = <1>;
++ #size-cells = <0>;
++ reg = <0x0>; /* GEM_ID */
++ fsl,gemac-bus-id = <0x0>; /* BUS_ID */
++ fsl,gemac-phy-id = <0x2>; /* PHY_ID */
++ fsl,mdio-mux-val = <0x0>;
++ phy-mode = "sgmii";
++ fsl,pfe-phy-if-flags = <0x0>;
++
++ mdio@0 {
++ reg = <0x1>; /* enabled/disabled */
++ };
++};
