This module provides a driver for the independent MDIO bus |

controllers found in the ASPEED AST2600 SoC. This is a driver for the |
|
third revision of the ASPEED MDIO register interface - the first two |
|
revisions are the "old" and "new" interfaces found in the AST2400 and |
|
AST2500, embedded in the MAC. For legacy reasons, FTGMAC100 driver |
|
continues to drive the embedded MDIO controller for the AST2400 and |

AST2500 SoCs, so say N if AST2600 support is not required. |
