Trivial patch updating my email contact details due to change of employer, and because I no longer have access to the previously used domain. Unfortunately I also no longer have access to any ads7828 hardware, but am happy to support/maintain the driver if others are able to test changes.

-----------------
|
|
|
|
* 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

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.
