+* 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

+Example:

+       compatible = "avia,hx711";
+       sck-gpios = <&gpio3 10 GPIO_ACTIVE_HIGH>;
+       dout-gpios = <&gpio0 7 GPIO_ACTIVE_HIGH>;
+       avdd-suppy = <&avdd>;
