iio: adc: hx711: Add IIO driver for AVIA HX711 This is the IIO driver for AVIA HX711 ADC which is mostly used in weighting cells. The protocol is quite simple and using GPIOs: One GPIO is used as clock (SCK) while another GPIO is read (DOUT) The raw value read from the chip is delivered. To get a weight one needs to subtract the zero offset and scale it. Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
