+       help
+         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
+          data
+
+         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
