    netdev/of/phy: New function: of_mdio_find_bus(). · 25106022
    David Daney authored
    Add of_mdio_find_bus() which allows an mii_bus to be located given its
    associated the device tree node.
    
    This is needed by the follow-on patch to add a driver for MDIO bus
    multiplexers.
    
    The of_mdiobus_register() function is modified so that the device tree
    node is recorded in the mii_bus.  Then we can find it again by
    iterating over all mdio_bus_class devices.
    
    Because the OF device tree has now become an integral part of the
    kernel, this can live in mdio_bus.c (which contains the needed
    mdio_bus_class structure) instead of of_mdio.c.
