It's because the device tree is not done correctly ... The bindings are
recent,
and may change soon. This whole issue has triggered some discussion on IRC
about them.
I'm not saying the system is perfect but this issue is more related to
recent
bindings that the of thing as a whole. That's more the problem with of
is that
when you need to define bindings for something that has none, you may not
anticipate everything ....
