  13Module Parameters
  14-----------------
  15
  16* reset boolean
  17  (default 0)
  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

  22Description
  23-----------
  24
  25This driver implements support for Winbond W83L786NG/W83L786NR chips.
  26
  27The driver implements two temperature sensors, two fan rotation speed
  28sensors, and three voltage sensors.
  29
  30Temperatures are measured in degrees Celsius and measurement resolution is 1
  31degC for temp1 and temp2.
  32
  33Fan rotation speeds are reported in RPM (rotations per minute). Fan readings
  34readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64
  35or 128 for fan 1/2) to give the readings more range or accuracy.
  36
  37Voltage sensors (also known as IN sensors) report their values in millivolts.
  38An alarm is triggered if the voltage has crossed a programmable minimum
  39or maximum limit.

  41/sys files
  42----------
  43
  44pwm[1-2] - this file stores PWM duty cycle or DC value (fan speed) in range:
  45            0 (stop) to 255 (full)
  46pwm[1-2]_enable - this file controls mode of fan/temperature control:
  47            * 0 Manual Mode
  48            * 1 Thermal Cruise
  49            * 2 Smart Fan II
  50            * 4 FAN_SET
  51pwm[1-2]_mode - Select PWM of DC mode
  52            * 0 DC
  53            * 1 PWM
  54tolerance[1-2] - Value in degrees of Celsius (degC) for +- T
