Subject: [PATCH net-next v2 4/5] net: mdio: Move MDIO drivers into a new subdirectory
Move all the MDIO drivers and multiplexers into drivers/net/mdio. The
mdio core is however left in the phy directory, due to mutual
dependencies between the MIOD core and the PHY core.
Take this opportunity to sort the Kconfig based on the menuconfig
strings, and move the multiplexers to the end with a separating
comment.

- help
- 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.
