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 below for an example of how to define
-a PHY.
+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
};

+* 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.
