+* 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
+
+Recommended properties:
+ - gain: Gain select, can be 32, 64 or 128
+ default is 128
+
+Optional properties:
+
+Example:
+weight@0 {
+ compatible = "avia,hx711";
+ sck-gpios = <&gpio3 10 GPIO_ACTIVE_HIGH>;
+ dout-gpios = <&gpio0 7 GPIO_ACTIVE_HIGH>;
+ gain = <32>
