We just need to mention that some generic drivers, such as ehci, may use
multiple phys, and for such drivers referencing phy(s) by name(s) does
not make sense. Instead of inventing elaborate naming schemes and
producing custom code to iterate over names, such drivers are better of
using nameless phy bindings and using this newly introduced API to
iterate through them.

Thanks.
