  12 Description
  13 -----------
  14
  15 The Maxim MAX31785 is a PMBus device providing closed-loop, multi-channel fan
  16 management with temperature and remote voltage sensing. Various fan control
  17 features are provided, including PWM frequency control, temperature hysteresis,
  18 dual tachometer measurements, and fan health monitoring.
  19
  20 For dual rotor fan configuration, the MAX31785 exposes the slowest rotor of the
  21 two in the fan[1-4]_input attributes.

  23 Usage Notes
  24 -----------
  25
  26 This driver does not probe for PMBus devices. You will have to instantiate
  27 devices explicitly.
