Fast GPIO (output) on i.MX6

My application need to respond with a digital pulse to event. The response must come within few microseconds from the event itself.

Therefore I think the /sys/gpio is too slow for me.

Can someone point me to documentation how to do it using physical memory access (using /dev/mem)?
