The Data Modul TP 72037 EasyTouch controller is derived from EGALAX
controller and is capable of detecting dual contacts. Packets can be 5
bytes or 10 bytes long, depending whether one or two contacts are
detected. Format is same as EGALAX touch controller, but with x and y
coordinates inverted.

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:

This patch adds a driver for Synaptics USB touchpad or pointing stick
devices. These USB devices emulate an USB mouse by default, so one can
also use the usbhid driver. However, in combination with special user
space drivers this kernel driver allows one to customize the behaviour
of the device.
An extended version of this driver with support for the cPad background
display can be found at
<http://jan-steinhoff.de/linux/synaptics-usb.html>.

As noted by Arve and others, since wall time can jump backwards, it is
difficult to use for input because one cannot determine if one event
occurred before another or for how long a key was pressed.
However, the timestamp field is part of the kernel ABI, and cannot be
changed without possibly breaking existing users.
This patch adds a new IOCTL that allows a clockid to be set in the
evdev_client struct that will specify which time base to use for event
timestamps (ie: CLOCK_MONOTONIC instead of CLOCK_REALTIME).
For now we only support CLOCK_MONOTONIC and CLOCK_REALTIME, but
in the future we could support other clockids if appropriate.
The default remains CLOCK_REALTIME, so we don't change the ABI.

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.

We don't actually care if the device has been runtime suspended immediately
so we can just drop the reference without waiting for any state change to
be implemented. This may allow us to avoid some suspend/resume cycles and
is a bit more friendly to the rest of the system.

Because we are using platform_device_probe() to register the driver
we do not need to assign driver's probe method. We also can mark
ske_keypad_probe(), together with ske_keypad_chip_init(), as __init
instead of __devinit.
