I am working with Intel Atom E3900, and I want to test specific GPIO pins (Linux is running). I am not able to find correct offset for example GPIO_3
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make thi...

I am not able to find correct offset for example GPIO_3 on line B39 and GPIO_2 on line C39. These pins are connected on header of my board. So i want to export correct pins (inside linux), change voltage value on them and verify that change with ...
