52 features, including extra voltage measurement inputs and PECI support. All
56 The ADT747x uses the 2-wire interface compatible with the SMBus 2.0
58 temperatures and two (2) or more voltages. It has four (4) 16-bit counters
59 for measuring fan speed. There are three (3) PWM outputs that can be used
62 A sophisticated control system for the PWM outputs is designed into the
65 programmable. Once configured, the ADT747x will adjust the PWM outputs in
73 The ADT747x samples all inputs continuously. The driver will not read

116 The ADT747x has a 10-bit ADC and can therefore measure temperatures
125 -----------------
129 - point1: Set the PWM speed at the lower temperature bound
130 - point2: Set the PWM speed at the higher temperature bound
135 PWM outputs, and a given PWM output can be controlled by several temperature
143 At Tmin - hysteresis the PWM output can either be off (0% duty cycle) or at the
145 `pwm[1-*]_stall_disable sysfs attribute`. A value of 0 means the fans will shut
150 set the value in ms in the `temp[1-*]_smoothing` sysfs attribute.
