   I only see i.Mx6 GPIO examples using /sys/class/gpio
   Example:
   

   Code:

   echo out > /sys/class/gpio/gpio40/direction
   echo 1   > /sys/class/gpio/gpio40/value
   

   Is it not possible to also do it with memory mapped IO, using standard Linux mmap????
   
   If so, how do I get going? Is there a nice .h header with register-definitions etc.?
   
   Thanks.
   P.
