This isn't an unambigiously clear statement, especially for MFDs where
there might be a desire to have some function on the device be able to
wake the system (eg, headset button press on an audio CODEC or a RTC on
a PMIC) even if there's no control within the device...

...as the commit log does hint at.  If there's a problem I think we need
some finer grained control here.
