Hi Ayan,

This issue is the point I'm get difficulties with and would appreciate
your clarifications.
Is the wakeup source relevant only for suspend/resume , or also for
runtime PM ? for example, is the keybaord example , which you linked,
relevant for runtime PM too ?
If yes - is the keybaord interrupt wakeup only the keyboard driver,
and nothing else, including the cpu ?

Thanks,
Ran
