18 Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
19 behavior is no chip reset to preserve BIOS settings
25 This driver implements support for Winbond W83L786NG/W83L786NR chips.
27 The driver implements two temperature sensors, two fan rotation speed
28 sensors, and three voltage sensors.
30 Temperatures are measured in degrees Celsius and measurement resolution is 1
31 degC for temp1 and temp2.
33 Fan rotation speeds are reported in RPM (rotations per minute). Fan readings
34 readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64
35 or 128 for fan 1/2) to give the readings more range or accuracy.
37 Voltage sensors (also known as IN sensors) report their values in millivolts.
38 An alarm is triggered if the voltage has crossed a programmable minimum
44 pwm[1-2] - this file stores PWM duty cycle or DC value (fan speed) in range:
45 0 (stop) to 255 (full)
46 pwm[1-2]_enable - this file controls mode of fan/temperature control:
51 pwm[1-2]_mode - Select PWM of DC mode
54 tolerance[1-2] - Value in degrees of Celsius (degC) for +- T
