Brief summary

GPIO numbering changed between v0.7.5 and v0.8.0-rc1

How reproducible

How to reproduce

Just run ls /sys/class/gpio

Expected behavior

root@rte:~# ls /sys/class/gpio/
export  gpio12   gpio400  gpio402  gpio404  gpio406  gpio408  gpio410  gpio412  gpio414  gpio6      gpiochip352  unexport
gpio11  gpio199  gpio401  gpio403  gpio405  gpio407  gpio409  gpio411  gpio413  gpio415  gpiochip0  gpiochip400

Unless other elements of the ecosystem that leverage this functionality can be adjusted appropriately.

Actual behavior

root@rte:~# ls -al /sys/class/gpio/

@EduKav1813 I would start by researching the source of the changes. I recall some discussion in the issue/PR about the changed GPIO numbering.
