I've applied Rafael's s2idle-dell-test branch to 4.12.0-rc3 and tested
on a Dell 9365 and, whilst it's significantly improved, it's not yet
working correctly.

Previously I could suspend (s2idle and deep), but it took an awkward
~8 second press of the power button to get it to resume, and I could
never get resume to work when triggering suspend/resume via close/open
of the lid.

With this patchset applied, I can suspend (s2idle) and a momentary
press of the power button resumes successfully.  I can also use the
lid switch to both suspend and resume successfully.

However, the EC events appear to trigger the machine to wake very
frequently whilst it's supposed to be suspended. This is visible via
the kernel messages at the end of this mail (leaving it in a suspended
state for a few hours resulted in many thousands of these messages),
and the high power draw witnessed.

Let me know if there's anything I can do to help debug further.
