Fair enough - but i still think it has nothing to do with dt binding
itself -> and i think the discussion we've had should be good for the
binding provided in this patch.. I hope.. if documentation needs a bit
of better explanation to prevent a repeat of the same discussion at a
later point of time, now might be a good time to add it in.
