-Maxim Integrated DS4422/DS4424 7-bit Sink/Source Current DAC Device Driver
-
-Datasheet publicly available at:
-https://datasheets.maximintegrated.com/en/ds/DS4422-DS4424.pdf
-
-Required properties:
-       - compatible: Should be one of
-               maxim,ds4422
-               maxim,ds4424
-       - reg: Should contain the DAC I2C address
-
-Optional properties:
-       - vcc-supply: Power supply is optional. If not defined, driver will ignore it.
-
-Example:
-       ds4224@10 {
-               compatible = "maxim,ds4424";
-               reg = <0x10>; /* When A0, A1 pins are ground */
-               vcc-supply = <&vcc_3v3>;
-       };
