The driver supports chipsets ILI2102, ILI2102s, ILI2103, ILI2103s and
ILI2105. Such kind of controllers can be found in Amazon Kindle Fire
devices.

Several fixes based on customer feedback:
* WHO_AM_I value has changed since preliminary parts used for initial
testing;
* Output of le16_to_cpu must be saved to memory before shifting to
preserve sign;
* Initial data rate was not extracted from data control register init.
This was causing the initial data rate to be set to maximum until
it was changed. To fix this problem, it made more sense to specify
initial data rate and extract the register mask from that.

This patch adds support for TI's touchscreen
controller for a 4/5/8 wire resistive panel
that is directly fed to the ADC.
This touchscreen controller will be part of
AM335x TI SoC. The TRM can be found at:

Cypress TrueTouch(tm) Standard Product controllers are found in
a wide range of embedded devices. This driver add support for a
variety of TTSP controllers.
Since the hardware is capable of tracking identifiable contacts, multi-touch
protocol type B (stateful) is used to report contact information.
The driver is composed of a core driver that process the data sent by
the contacts and a set of bus specific interface modules. This patch
adds the base core TTSP driver.

Some displays from AUO have a so called in-cell touchscreen, meaning it
is built directly into the display unit.
Touchdata is gathered through PIXCIR Tango-ICs and processed in an
Atmel ATmega168P with custom firmware. Communication between the host
system and ATmega is done via I2C.
Devices using this touch solution include the Dell Streak5 and the family
of Qisda ebook readers.
The driver reports single- and multi-touch events including touch area
values.

This driver adds support for Sharp's GP2AP002A00F proximity sensor. The
proximity is measured as a binary switch, i.e. an object is either
detected or not detected. Hence, this driver is implemented as a switch
that reports SW_FRONT_PROXIMITY.

There exist tilt switches that simply report their tilt-state via
some gpios. The number and orientation of their axes can vary
depending on the switch used and the build of the device. Also two
or more one-axis switches could be combined to provide multi-dimensional
orientation.
One example of a device using such a switch is the family of Qisda
ebook readers, where the switch provides information about the
landscape / portrait orientation of the device. The example in
Documentation/input/gpio-tilt.txt documents exactly this one-axis
device.

The ADP5585 family keypad decoder and IO expander is similar to the ADP5589,
however it features less IO pins, and lacks hardware assisted key-lock
functionality. Unfortunately the register addresses are different, as well as
the event codes and bit organization within the port related registers.
Move ADP5589 Register defines from the header file into the main source file.
Add new defines while making sure we don't break existing platform_data.
Add register address translation, and turn device specific defines into variables.
Introduce some helper functions and disable functions that doesn't
exist on the added devices.
