Stop this broken thinking. The solution is simple.
Put the generic runtime PM changes into the PM tree in a separate /clean/
branch. Merge them into the PM-next branch. Notify me where I can
pull that /clean/ branch.
I pull that clean branch into my tree, and then apply the AMBA specific
patches on top.
That means Rafael has the PM changes, I have the dependent PM changes,
and I also have the AMBA changes, and no one ends up carrying changes
which are inappropriate.
