Indeed. The driver and the binding before that don't really belong either, I would have NAK'd those on devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, though it appears I either missed them or they never made it to that list. >>From my PoV there should not be a platform-specific ION binding. If we need one at all, people should work on the proposed generic binding [1] or figure out how to do this with the existing reserved-memory bindings. Thanks, Mark.
