I do not believe it is Linux specific, it describes desired behavior of
hardware regardless of OS. I mean you want your device to wake up if you
press power button whether it runes Linux, Windows, FreeBSD or whatever.

I should have said to use "wakeup-source", not simply "wakeup" so that
we'd match with I2C annotation.
