   4 Required properties:
   5  - compatible:  Should be "avia,hx711"
   6  - sck-gpios:   Definition of the GPIO for the clock
   7  - dout-gpios:  Definition of the GPIO for data-out
   8                 See Documentation/devicetree/bindings/gpio/gpio.txt
   9  - avdd-supply: Definition of the regulator used as analog supply
  10
  11 Optional properties:
  12  - clock-frequency:     Frequency of PD_SCK in Hz
  13                         Minimum value allowed is 10 kHz because of maximum
  14                         high time of 50 microseconds.
