+Kernel driver w83l786ng
+=====================
+
+Supported chips:
+  * Winbond W83L786NG/W83L786NR
+    Prefix: 'w83l786ng'
+    Addresses scanned: I2C 0x2e - 0x2f
+    Datasheet: http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L786NRNG09.pdf
+
+Author: Kevin Lo <kevlo@kevlo.org>
+
+
+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
+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.
