I built new kernel with device gpio, something is not working - F/D
should mean 'factory default' aka 'reset switch', but it does not sense
status ot that switch. No matter whether pressed or not, gpioctl still
reports 0.

Also, somehow strangely, in dmesg:

gpio0: <Cavium Octeon GPIO driver> on ciu0

GIANT-LOCKED line is there 16 times, once for every one from 16 pins -
why?
