Right.. that is why I was curious how you posted a patch that
supposedly supports sleep pin configurations in a kernel that does not
support suspend-resume?

Hopefully we will have it supported in 3.18 kernel[1] - still need out
of tree wakeup timer patch[2] for testing though..

If you have at least tested on relevant branch which has the feature
expected for 3.18, I might still be OK with the patch.
