+Description
+-----------
+
+This driver implements support for the Texas Instruments ADS7828.
+
+This device is a 12-bit 8-channel A-D converter.
+
+It can operate in single ended mode (8 +ve inputs) or in differential mode,
+where 4 differential pairs can be measured.
+
+The chip also has the facility to use an external voltage reference.  This
+may be required if your hardware supplies the ADS7828 from a 5V supply, see
+the datasheet for more details.

 There is quite some difference between these chips, but they are similar
 enough that it was sensible to put them together in one driver.
-The W83627HF chip is assumed to be identical to the ISA W83782D.
 The Asus chips are similar to an I2C-only W83782D.

+-----------
+
+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.
