-Subject: [PATCH] mdio_bus: Add generic mdio_find_bus()
-
-It appears most ethernet drivers follow one of two main strategies
-for mdio bus/phy management. A monolithic model where the net driver
-itself creates, probes and uses the phy, and one where an external
-mdio/phy driver instantiates the mdio bus/phy and the net driver
-only attaches to a known phy. Usually in this latter model the phys
-are discovered via DT relationships or simply phy name/address
-hardcoding.
-
-This is a shame because modern well behaved mdio buses are self
-describing and can be probed. The mdio layer itself is fully capable
-of this, yet there isn't a clean way for a standalone net driver
-to attach and enumerate the discovered devices. This is because
-outside of of_mdio_find_bus() there isn't a straightforward way
-to acquire the mii_bus pointer.
-
-So, lets add a mdio_find_bus which can return the mii_bus based
-only on its name.
