IMO it's not that bad. While I haven't gone over the code at all, I've
used it on an OMAP4 and it does work (which is pretty neat to see!).

Going by Mark's comments, While it'd be nice to hear from Janos and
Jaska as well, since yours is the only actual code that is available and
being taken forward through the merging process, I think we're fine
going ahead with it.

We're trying for much quicker releases now, so missing the 2.0 boat
really isn't catastrophic at all.

So if you could rebase and send these in a more review-friendly format
(git send-email or a git tree somewhere), that would help move this
forwards. We might have our hands full for a short while getting the
outstanding patches and bugs done for 2.0, but I'd certainly like to try
to get this in for 3.0 (i.e., the next release) if everything looks
good.
