* ENETC ethernet device tree bindings



Depending on board design and ENETC port type (internal or

external) there are two supported link modes specified by

below device tree bindings.



Required properties:



- reg		: Specifies PCIe Device Number and Function

		  Number of the ENETC endpoint device, according

		  to parent node bindings.

- compatible	: Should be "fsl,enetc".



1) The ENETC external port is connected to a MDIO configurable phy:



In this case, the ENETC node should include a "mdio" sub-node

that in turn should contain the "ethernet-phy" node describing the

external phy.  Below properties are required, their bindings

already defined in ethernet.txt or phy.txt, under

Documentation/devicetree/bindings/net/*.



Required:



- phy-handle		: Phandle to a PHY on the MDIO bus.

			  Defined in ethernet.txt.



- phy-connection-type	: Defined in ethernet.txt.



- mdio			: "mdio" node, defined in mdio.txt.



- ethernet-phy		: "ethernet-phy" node, defined in phy.txt.



Example:



	ethernet@0,0 {

		compatible = "fsl,enetc";

		reg = <0x000000 0 0 0 0>;

		phy-handle = <&sgmii_phy0>;

		phy-connection-type = "sgmii";



		mdio {

			#address-cells = <1>;

			#size-cells = <0>;

			sgmii_phy0: ethernet-phy@2 {

				reg = <0x2>;

			};

		};

	};



2) The ENETC port is an internal port or has a fixed-link external

connection:



In this case, the ENETC port node defines a fixed link connection,

as specified by "fixed-link.txt", under

Documentation/devicetree/bindings/net/*.



Required:



- fixed-link	: "fixed-link" node, defined in "fixed-link.txt".



Example:

	ethernet@0,2 {

		compatible = "fsl,enetc";

		reg = <0x000200 0 0 0 0>;

		fixed-link {

			speed = <1000>;

			full-duplex;

		};

	};
