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 pointer to the mii_bus, or NULL if none found.
   
   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.
