+* Analog Devices AD5272 digital potentiometer
+
+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>;
+};
