Hi Kishon,

The PHY framework provides a set of APIs for the PHY drivers to
create/destroy a PHY and APIs for the PHY users to obtain a reference to the
PHY with or without using phandle. To obtain a reference to the PHY without
using phandle, the platform specfic intialization code (say from board file)
should have already called phy_bind with the binding information. The binding
information consists of phy's device name, phy user device name and an index.
The index is used when the same phy user binds to mulitple phys.
PHY drivers should create the PHY by passing phy_descriptor that has
describes the PHY (label, type etc..) and ops like init, exit, suspend, resume,
poweron, shutdown.
The documentation for the generic PHY framework is added in
Documentation/phy.txt and the documentation for the sysfs entry is added
in Documentation/ABI/testing/sysfs-class-phy.

Shouldn't these be -ENOSYS ? EOPNOTSUPP is defined by POSIX as
"Operation not supported on socket". And EOPNOTSUPP appears to be
mostly used in the network code in the kernel.
