nanopc-t1 gpio2

I have working on nanopc-t1 and I need to connect input device to digital
IO (GPIO2) ( PIN 8 and PIN 9) but I don't know how this pins map to the
GPIO class (/sys/class/gpio) if you have any information please share with
me.

I'll try do describe how to use GPIO tomorrow on my webpage:

Don't care about PL lang. I'll write it in EN :)
