+Module Parameters
+-----------------
+
+* reset boolean
+    (default 0)
+
+    Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
+    behavior is no chip reset to preserve BIOS settings

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