-* Analog Devices AD5820 autofocus coil
-
-Required Properties:
-
-  - compatible: Must contain one of:
-		- "adi,ad5820"
-		- "adi,ad5821"
-		- "adi,ad5823"
-
-  - reg: I2C slave address
-
-  - VANA-supply: supply of voltage for VANA pin
-
-Optional properties:
-
-   - enable-gpios : GPIO spec for the XSHUTDOWN pin. The XSHUTDOWN signal is
-active low, a high level on the pin enables the device.
-
-Example:
-
-       ad5820: coil@c {
-               compatible = "adi,ad5820";
-               reg = <0x0c>;
