Yes, that was merely a convenience branch for reviewers; I see actual 
pull requests as being for maintainers, whereas I'm just some oik ;)

Yeah, all of the options were pretty horrible, but this one was about 
the most concise and didn't need to introduce any new infrastructure. We 
have this "PMU as a child of some other device" issue coming up on 
various other IP blocks as well; the resource claiming conflicts seem to 
get in the way the most.

Thanks for applying!

Robin.
