Hi Grant

I'm no export with barebox. So i just grep'ed the code.

It parses the property. Also as with linux, of_find_node_by_path()
does not stop at : as you say it should.

There is one case of the property being updated, but that is only for
the PPC mpc85xx.

Barebox does not appear to use 'current-speed' at all.
