+
+Datasheet publicly available at:
+https://datasheets.maximintegrated.com/en/ds/DS4422-DS4424.pdf
+
+Required properties:
+ - compatible: Should be one of
+ maxim,ds4422

+
+Optional properties:
+ - vcc-supply: Power supply is optional. If not defined, driver will ignore it.
+
+Example:
+ ds4224@10 {
+ compatible = "maxim,ds4424";

+ vcc-supply = <&vcc_3v3>;
+ };
