Subject: net: mdio-uclass: introduce dm_eth_phy_connect_interface()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8db554dcbb2374a2dea130af56d781732070beb7;p=thirdparty%2Fu-boot.git

net: mdio-uclass: introduce dm_eth_phy_connect_interface()

dm_eth_phy_connect_interface() is a variant of dm_eth_phy_connect() that
allows to set the used PHY mode, in case the MAC driver needs to fix it
up. The previously static dm_eth_connect_phy_handle() is renamed and
extended for this purpose.
