Thanks a lot for suggestion, it's actually looks what's needed here instead of
this driver. Anyways, there is no IIO_PROXIMITY support inside supported types
in iio_hwmon.c. Should I add additional case inside this driver for
IIO_PROXIMITY type?

I'm not sure either but it exists :) And it's exactly for this purpose:
"someone opened the chassis", "how near/far is cover?".
