I'm working on Beagle Bone Black, and I need to change the power button 
behaivor.


Img that I'm using: *bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.img*


As the documentation says, this button can wakeup is the module has in 
suspend mode.


REF: BBONEBLK_SRM BeagleBone Black System Reference Manual Rev C.1
6.1.8.5 WAKEUP 
The WAKEUP signal from the TPS65217C is connected to the EXT_WAKEUP signal 
on the processor. 
This is used to wake up the processor when it is in a sleep mode. 
When an event is detected by the TPS65217C, such as the power button being 
pressed, it generates this signal.


A note: 
At this moment, if I press the power button the BBB proceed to shutdown. 
But, if the BBB is suspended, when I press the power button doesn't wake 
up. 
I need to change this behavior to wake up the module. –


Anybody knows how can I change it? 

Thanks a lot!
