depends on MDIO_DEVRES
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.

config MDIO_REGMAP
tristate
help
This driver allows using MDIO devices that are not sitting on a
regular MDIO bus, but still exposes the standard 802.3 register
layout. It's regmap-based so that it can be used on integrated,
memory-mapped PHYs, SPI PHYs and so on. A new virtual MDIO bus is
created, and its read/write operations are mapped to the underlying
regmap. Users willing to use this driver must explicitly select
REGMAP.
