Bindings for the Maxim MAX31760 Intelligent Fan Controller

==========================================================



The Maxim MAX31760 is a i2c device providing closed-loop, multi-channel fan

management with temperature. Various fan control features are provided,

including PWM frequency control, temperature hysteresis, dual tachometer

measurements, and fan health monitoring.

The Maxim MAX31760 is a i2c device and will register as a cooling device.

MAX31760 fan controller supports different PWM frequencies, which can be

used as cooling device levels by controlling the fan speed.
