^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Description

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) The Maxim MAX31785 is a PMBus device providing closed-loop, multi-channel fan
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) management with temperature and remote voltage sensing. Various fan control
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) features are provided, including PWM frequency control, temperature hysteresis,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) dual tachometer measurements, and fan health monitoring.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) For dual-rotor configurations the MAX31785A exposes the second rotor tachometer
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) readings in attributes fan[5-8]_input. By contrast the MAX31785 only exposes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) the slowest rotor measurement, and does so in the fan[1-4]_input attributes.
