* 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. Example: weight { compatible = "avia,hx711"; sck-gpios = <&gpio3 10 GPIO_ACTIVE_HIGH>; dout-gpios = <&gpio0 7 GPIO_ACTIVE_HIGH>; avdd-suppy = <&avdd>; clock-frequency = <100000>; };
