| 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. | ||
