This patch adds the TSC-40 serial touchscreen driver and should be
compatible with TSC-10 and TSC-25.

The driver was written by Linutronix on behalf of Bachmann electronic GmbH.

Add MAXI max11801 resistive touchscreen controller driver. This driver
uses Auto Mode and Aperture Mode.

Support for other max1180x devices can be added to this driver as well,
as they use almost the same register addresses and codes.

Introduce a driver for the Texas Instruments TSC2005 touchscreen
controller (http://focus.ti.com/docs/prod/folders/print/tsc2005.html).

The patch is based on a driver by Lauri Leukkunen, with modifications
by David Brownell, Phil Carmody, Imre Deak, Hiroshi DOYU, Ari Kauppi,
Tony Lindgren, Jarkko Nikula, Eero Nurkkala and Roman Tereshonkov.

Since the driver will be supporting whole range of Atmels mXT touchscreen
controllers we better rename it to atmel_mxt_ts.

Some of the WM831x series of PMICs from Wolfson Microelectronics include
a resistive touchscreen controller. Implement support for these controllers
within the input API.

Platform data is supported to allow configuration of system parameters such
as selection between four and five wire touchscreens and for specification
of optional direct to CPU IRQs for sample availability and for pen down.
Use of this feature for at least the data IRQ is strongly recommended.

Thanks to Julien Boibessot for extensive testing and detailed feedback.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
