-
-The node for this device must be a child node of a I2C controller, hence
-all mandatory properties for your controller must be specified. See directory:
-
-        Documentation/devicetree/bindings/i2c
-
-for more details.
-
-Required properties:
-       - compatible:   Must be one of the following, depending on the model:
-                       adi,ad5272-020
-                       adi,ad5272-050
-                       adi,ad5272-100
-                       adi,ad5274-020
-                       adi,ad5274-100
-
-Optional properties:
- - reset-gpios: GPIO specification for the RESET input. This is an
-               active low signal to the AD5272.
-
-Example:
-ad5272: potentiometer@2f {
-       reg = <0x2F>;
-       compatible = "adi,ad5272-020";
-       reset-gpios = <&gpio3 6 GPIO_ACTIVE_HIGH>;
-};
