There exists several examples today of devices that embed an ethernet PHY or PCS directly inside an SoC. In this situation, either the device is controlled through a vendor-specific register set, or sometimes exposes the standard 802.3 registers that are typically accessed over MDIO. As phylib and phylink are designed to use mdiodevices, this driver allows creating a virtual MDIO bus, that translates mdiodev register accesses to regmap accesses. The reason we use regmap is because there are at least 3 such devices known today, 2 of them are Altera TSE PCS's, memory-mapped, exposed with a 4-byte stride in stmmac's dwmac-socfpga variant, and a 2-byte stride in altera-tse. The other one (nxp,sja1110-base-tx-mdio) is exposed over SPI.
