| * 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>; |
| }; |
