The PMIC sends an interrupt to the A64 when the Power button is pressed and you can read/write registers on the PMIC to configure the behavior a bit. In linux the powerbutton is also a event device (think /dev/input/eventXXX) and you can watch for those events with a tool like evtest ... on my Ubuntu images with Mate Desktop the power button brings up the normal Reboot/Shutdown menu, so I guess they already wired up some udev rules for that...

Thank you very much for the clarification, I'll give that a look and luckily make it able to shutdown. Right now either of them does nothing at all!
It is indeed in the /dev/input/event1.
When the button is pressed, weird characters are written to it.
Any idea on how I can make it so when the button is pressed "init 0" command is executed? Total noob to udev rules
