How to run a function after power key press?

[sujay1]

I'm using am imx6slevk with yocto bsp, on leaving the board idle for 10 minutes the console goes off(wait mode) and it turns back on when I press the power button,

The requirement is to run a function when the power button is pressed (the function merely turns on 2 gpios). 

I'm not sure how to detect a power key press and which header file to include for the same, does anyone have any idea how to integrate this?

Thanks in advance
