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

struct device_node * 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.
