How should a wakeup source for a device be configured in code.
I could not find it documented anywhere.

Check out drivers/input/keyboard/samsung-keypad.c. It is configured as
a wakeup source:-
1. device_init_wakeup() - configuring the device to be of wakeup type
2. enable_irq_wake() - configuring the interrupt to be of wakeup type.

True, I could not find the documentation for the same.

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
