NAME

6       of_mdio_find_bus - Given an mii_bus node, find the mii_bus.
7

SYNOPSIS

9       struct mii_bus * of_mdio_find_bus(struct device_node * mdio_bus_np);
10

ARGUMENTS

12       mdio_bus_np
13           Pointer to the mii_bus.
14

DESCRIPTION

16       Returns a reference to the mii_bus, or NULL if none found. The embedded
17       struct device will have its reference count incremented, and this must
18       be put once the bus is finished with.
19
20       Because the association of a device_node and mii_bus is made via
21       of_mdiobus_register, the mii_bus cannot be found before it is
22       registered with of_mdiobus_register.
