Back when pmf was being designed, I strongly urged that it include the concept of power domains under which device could be grouped.As long as the tree is flat, it doesn't matter at all. If it isn't the problem is interaction of different buses and for that you might end up with a heavily MD system.
While omap only a few buses, unrelated devices are grouped together in power domains. The problem is that on embedded systems, this type of power mgmt is very common and should not require MD hooks. The PM framework should handle this out of the box.
