I think you need to implement this now as this is a basic features of any USB controller and one which is already supported by the driver you are changing. We've also had a long of history of Qualcomm pushing incomplete implementations upstream and then they move on to more pressing deadline and never actually complete the work. This very wakeup support is a good example of this as parts of it was merged years ago and when someone later tried to get it to actually work, it turned into a complete hack of an implementation as no one had thought about the overall design.
