OF_MDIO_FIND_BUS(9)                   Network device support                  OF_MDIO_FIND_BUS(9)



NAME
       of_mdio_find_bus - Given an mii_bus node, find the mii_bus.

SYNOPSIS
       struct mii_bus * of_mdio_find_bus(struct device_node * mdio_bus_np);

ARGUMENTS
       mdio_bus_np
           Pointer to the mii_bus.

DESCRIPTION
       Returns a reference to the mii_bus, or NULL if none found. The embedded struct device will
       have its reference count incremented, and this must be put once the bus is finished with.

       Because the association of a device_node and mii_bus is made via of_mdiobus_register, the
       mii_bus cannot be found before it is registered with of_mdiobus_register.
