Great! Given the discussions on this topic before, it sure seemed like
no news was bad news here, but I guess not:-)

I'm going to add some new device tree content in 3.7 that will rely on
this patch to work. However, since it's a new feature/DT-content, I
don't think we need to manage the dependency any more than having this
and the other patches both show up in 3.7 at some time.

Thanks.
