The example I have in mind is a USB host controller device with both a high-speed EHCI controller function and some companion low/full-speed UHCI or OHCI controller functions. The EHCI driver relies on the fact that the EHCI controller has a higher function number and therefore is resumed _after_ the companion controllers. We need a way to express dependencies like this between devices. Or at least, there has to be a way to prevent certain devices from resuming in parallel.
