40 The ADT747x uses the 2-wire interface compatible with the SMBus 2.0
42 temperatures and two (2) or more voltages. It has four (4) 16-bit counters
43 for measuring fan speed. There are three (3) PWM outputs that can be used
46 A sophisticated control system for the PWM outputs is designed into the
48 three temperature sensors. Each PWM output is individually adjustable and
49 programmable. Once configured, the ADT747x will adjust the PWM outputs in
51 This feature can also be disabled for manual control of the PWM's.

83 ----------------
85 The ADT747x has a 10-bit ADC and can therefore measure temperatures
91 an optimal configuration for the automatic PWM control.
94 -----------------
96 The driver exposes two trip points per PWM channel.
98 point1: Set the PWM speed at the lower temperature bound
99 point2: Set the PWM speed at the higher temperature bound
101 The ADT747x will scale the PWM linearly between the lower and higher PWM
104 PWM outputs, and a given PWM output can be controlled by several temperature
105 channels. As a result, the ADT747x may compute more than one PWM value
107 fan speed) is applied. PWM values range from 0 (off) to 255 (full speed).
110 the PWM control exceeds temp#_max.
112 At Tmin - hysteresis the PWM output can either be off (0% duty cycle) or at the
114 pwm[1-*]_stall_disable sysfs attribute. A value of 0 means the fans will shut
119 set the value in ms in the temp[1-*]_smoothing sysfs attribute.
