I'm thinking of simply open-coding this for now, to avoid the use of
of_get_next_parent(). This is part of a set of patches that has gone
through countless revisions over the past two years and the timing
is such that adding yet another dependency will likely make it miss
the next cycle again. I'd really like to avoid that.

If nobody objects I'll volunteer to refactor this after v4.7-rc1.

Alternatively, perhaps Rob can give a very quick Acked-by on the
of_get_next_parent() addition, then I might still have time to take
this through one or two linux-next releases before sending out the
pull requests around the end of the week.
