Ohad, Tim,

For this patch to be useful to us we also need Suman's DT patch, so we
should try to get them both in asap.

Based on the long discussion we had on one of the previous iterations
of Suman's DT binding, with the DT maintainers I believe that it would
be fine to move along and sent Suman's patches to Linus - without an
explicit Ack from the DT guys (or did I just miss one?).

Regarding this patch I agree with Ohad that it would be good if we
verify that Mark's question is answered before moving on. So I will
reach out to him to see if he has any remaining concerns.
