Kernel driver ads7828
=====================
Supported chips:
* Texas Instruments/Burr-Brown ADS7828
Prefix: 'ads7828'
Addresses scanned: I2C 0x48, 0x49, 0x4a, 0x4b
Datasheet: Publicly available at the Texas Instruments website :
http://focus.ti.com/lit/ds/symlink/ads7828.pdf
Authors:
Steve Hardy <steve@linuxrealtime.co.uk>
Module Parameters
-----------------
* se_input: bool (default Y)
Single ended operation - set to N for differential mode
* int_vref: bool (default Y)
Operate with the internal 2.5V reference - set to N for external reference
* vref_mv: int (default 2500)
If using an external reference, set this to the reference voltage in mV
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.

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.
