   10 Required properties:
   11         - compatible:   Must be one of the following, depending on the model:
   12                         adi,ad5272-020
   13                         adi,ad5272-050
   14                         adi,ad5272-100

   21 
   22 Example:
   23 ad5272: potentiometer@2f {
   24         reg = <0x2F>;
   25         compatible = "adi,ad5272-020";
   26         reset-gpios = <&gpio3 6 GPIO_ACTIVE_HIGH>;
   27 };
