Please include intel and google on your patches because we'll be needing this support in the near future as well. The allocator limitations are known, and Kyosti and I have talked about improving things here. As for the children comment you need to reserve a sufficiently large mmio space and in the hotplug path one can allocate subdevices. Since it's inherently a hotplug there's no way to know what the topology will be when a device is plugged in.
