-
-The Maxim MAX31785 is a PMBus device providing closed-loop, multi-channel fan
-management with temperature and remote voltage sensing. Various fan control
-features are provided, including PWM frequency control, temperature hysteresis,
-dual tachometer measurements, and fan health monitoring.
-
-Required properties:
-- compatible     : One of "maxim,max31785" or "maxim,max31785a"
-- reg            : I2C address, one of 0x52, 0x53, 0x54, 0x55.
-
-Example:
-
-        fans@52 {
-                compatible = "maxim,max31785";
-                reg = <0x52>;
-        };
