* AVIA HX711 ADC chip for weight cells
Bit-banging driver
Required properties:
- compatible: Should be "avia,hx711"
- sck-gpios: Definition of the GPIO for the clock
- dout-gpios: Definition of the GPIO for data-out
See Documentation/devicetree/bindings/gpio/gpio.txt
- avdd-supply: Definition of the regulator used as analog supply
Optional properties:
- clock-frequency: Frequency of PD_SCK in Hz
Minimum value allowed is 10 kHz because of maximum
high time of 50 microseconds.
