Adapted from the same file name in the kernel device tree bindings
documentation, to use with U-Boot.

* TSEC-compatible ethernet nodes
Properties:
- compatible : Should be "fsl,tsec"
- reg : Offset and length of the register set for the device
- phy-handle : See ethernet.txt file in the same directory.
- phy-connection-type : See ethernet.txt file in the same directory. This
property is only really needed if the connection is of type "rgmii-id",
"rgmii-rxid" and "rgmii-txid" as all other connection types are detected
by hardware.
Example:
ethernet@24000 {
compatible = "fsl,tsec";
reg = <0x24000 0x1000>;
phy-handle = <&phy0>;
phy-connection-type = "sgmii";
};
Child nodes of the TSEC controller are typically the individual PHY devices
connected via the MDIO bus (sometimes the MDIO bus controller is separate).
* MDIO IO device
The MDIO is a bus to which the PHY devices are connected. For each
device that exists on this bus, a PHY node should be created.
Required properties:
- compatible : Should define the compatible device type for the
mdio. Currently supported string/device is "fsl,tsec-mdio".
- reg : Offset and length of the register set for the device
Example:
mdio@24520 {
compatible = "fsl,tsec-mdio";
reg = <0x24520 0x20>;
ethernet-phy@0 {
reg = <0>;
};
};
