In linux kernel since version 4.2 (release Date: 2015-08-30)  
If you say yes here you get support for AVIA HX711 ADC which is used
for weigh cells

This driver uses two GPIOs, one acts as the clock and controls the
channel selection and gain, the other one is used for the measurement

Currently the raw value is read from the chip and delivered.
To get an actual weight one needs to subtract the
zero offset and multiply by a scale factor.
This should be done in userspace.

This driver can also be built as a module. If so, the module will be
called hx711.
