The instructions at https://docs.getchip.com/chip.html#making-stuff for reading input from GPIO refer to "XIO-P7", but refer to /sys/class/gpio/gpio1019 (for 4.4.13-ntc-mlc), which seems to be connected to XIO-P6. I think the docs should be referring to /sys/class/gpio/gpio1020 in those cases (which does seem to correspond with XIO-P7.
