I'm working on Wake-on-Wireless support for wireless right now [1].
Upon wake up I wanted to inform the kernel of the event which caused
the wake up but am not clear if there is a generic API for this. Mind
you, for WoW we'll need at least some AC power to the card so we'll
need to at least be in S3-Hot so we'll only need events for that for
now.

Do we have some generic infrastructure to gather reasons for wake up
from S1-S4 and pass this to userspace yet?
