Imx7 Picopi gpio mapping and yocto

[maash]

Hi.

I'm scratching my head on how gpio pin names are mapped to actual user space accessable gpio names.

fe. I'm trying to toggle GPIO2_IO01. Normally I would just:

echo XX > /sys/class/gpio/export

However after trying to find something on here, wandboard forum (totally useless) and general googling I'm still no wiser. So any pointers would be appreciated!
