* MDIO IO device

The MDIO is a bus to which the PHY devices are connected.  For each
device that exists on this bus, a child node should be created.  See
the definition of the PHY node in booting-without-of.txt for an example
of how to define a PHY.

Required properties:
  - reg : Offset and length of the register set for the device
  - compatible : Should define the compatible device type for the
    mdio.  Currently, this is most likely to be "fsl,gianfar-mdio"

Example:

	mdio@24520 {
		reg = <24520 20>;
		compatible = "fsl,gianfar-mdio";

		ethernet-phy@0 {
			......
		};
	};

* TBI Internal MDIO bus

As of this writing, every tsec is associated with an internal TBI PHY.
This PHY is accessed through the local MDIO bus.  These buses are defined
similarly to the mdio buses, except they are compatible with "fsl,gianfar-tbi".
The TBI PHYs underneath them are similar to normal PHYs, but the reg property
is considered instructive, rather than descriptive.  The reg property should
be chosen so it doesn't interfere with other PHYs on the bus.

* Gianfar-compatible ethernet nodes

Properties:

  - device_type : Should be "network"
  - model : Model of the device.  Can be "TSEC", "eTSEC", or "FEC"
  - compatible : Should be "gianfar"
  - reg : Offset and length of the register set for the device
  - local-mac-address : List of bytes representing the ethernet address of
    this controller
  - interrupts : For FEC devices, the first interrupt is the device's
    interrupt.  For TSEC and eTSEC devices, the first interrupt is
    transmit, the second is receive, and the third is error.
  - phy-handle : The phandle for the PHY connected to this ethernet
    controller.
  - fixed-link : <a b c d e> where a is emulated phy id - choose any,
    but unique to the all specified fixed-links, b is duplex - 0 half,
    1 full, c is link speed - d#10/d#100/d#1000, d is pause - 0 no
    pause, 1 pause, e is asym_pause - 0 no asym_pause, 1 asym_pause.
  - phy-connection-type : a string naming the controller/PHY interface type,
    i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id", "sgmii",
    "tbi", or "rtbi".  This property is only really needed if the connection
    is of type "rgmii-id", as all other connection types are detected by
    hardware.
  - fsl,magic-packet : If present, indicates that the hardware supports
    waking up via magic packet.
  - bd-stash : If present, indicates that the hardware supports stashing
    buffer descriptors in the L2.
  - rx-stash-len : Denotes the number of bytes of a received buffer to stash
    in the L2.
  - rx-stash-idx : Denotes the index of the first byte from the received
    buffer to stash in the L2.

Example:
	ethernet@24000 {
		device_type = "network";
		model = "TSEC";
		compatible = "gianfar";
		reg = <0x24000 0x1000>;
		local-mac-address = [ 00 E0 0C 00 73 00 ];
		interrupts = <29 2 30 2 34 2>;
		interrupt-parent = <&mpic>;
		phy-handle = <&phy0>
	};
