Florian Fainelli says:

====================
net: broadcom MDIO support for broken turn-around

These two patches update the GENET and UniMAC MDIO controllers to deal with
PHYs that are known to have a broken turn-around bug (e.g: BCM53125 and others)

This utilizes the infrastructure that code recently added to do that in 'net-next'.

Note that the changes look nearly identical and I will try to address the MDIO
code duplication between GENET and UniMAC in a future patch series.

Changes in v2:
- remove brcmphy.h include in mdio-bcm-unimac.c
- use the same comment as with GENET's MDIO read function
