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

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.
