replaced by the skge driver.
Who: Stephen Hemminger <shemminger@osdl.org>
---------------------------
What: Compaq touchscreen device emulation
When: Oct 2007
Files: drivers/input/tsdev.c
Why: The code says it was obsolete when it was written in 2001.
tslib is a userspace library which does anything tsdev can do and
much more besides in userspace where this code belongs. There is no
longer any need for tsdev and applications should have converted to
use tslib by now.
The name "tsdev" is also extremely confusing and lots of people have
it loaded when they don't need/use it.

Say Y here if you have a touchscreen interface using the

ADS7846 or ADS7843 controller, and your board-specific setup
code includes that in its table of SPI devices.
If HWMON is selected, and the driver is told the reference voltage
on your board, you will also get hwmon interfaces for the voltage
(and on ads7846, temperature) sensors of this chip.
If unsure, say N (but it's safe to say "Y").
To compile this driver as a module, choose M here: the
