i saw http://lkml.iu.edu/hypermail/linux/kernel/1510.2/04553.html add a 
Documentation/devicetree/bindings/power/wakeup-source.txt for this, but 
that serial didn't remove all wakeup-source property from other 
bindings, but standardize them, for example:

Hi guys,

Mark Brown suggested to put wakeup-source support in some common place 
instead of sub drivers, should we do that?
