That turned out to be more challenging than I had thought initially.
The last version I sent was almost OK, but it had some issues (like it could walk the PCI hierarchy before resuming any PCI devices during system resume), so a new version follows. I did my best to avoid introducing any new problems with it, but I obviously might overlook something.
It works for me and doesn't seem to break anything as far as I can say.
[1/3] Make PM workqueue available for CONFIG_PM_RUNTIME unset. [2/3] Rework the handling of ACPI device wakeup notifications. [3/3] Enable wakeup GPEs while setting up devices for wakeup during system suspend too.
Thanks!
