24 | * TBI Internal MDIO bus | ||
25 | |||
26 | As of this writing, every tsec is associated with an internal TBI PHY. | ||
27 | This PHY is accessed through the local MDIO bus. These buses are defined | ||
28 | similarly to the mdio buses, except they are compatible with "fsl,gianfar-tbi". | ||
29 | The TBI PHYs underneath them are similar to normal PHYs, but the reg property | ||
30 | is considered instructive, rather than descriptive. The reg property should | ||
31 | be chosen so it doesn't interfere with other PHYs on the bus. | ||
