We will most likely rearm it yet again the IRQ thread so doing it here
is pointless.

We do not need process context to send input events so let's switch to
a regular timer. I am going to get rid of taking ts->mutex in
tsc2005_irq_thread() later.

Sparse in unhappy when people use 0 instead of NULL for pointers so
let's rework the way we initialize spi_transfer structure in
tsc2005_cmd() and tsc2005_write().

We need to make sure we have time/work initialized before requesting and
enabling interrupts, otherwise we might start using them way too early.

Newer code should not be using legacy suspend/resume methods but
rather supply dev_pm_ops structure as it allows better control

Instead of peeking into underlying device and using dev_get/set_drvdata(),
let's use SPI layer's implementation to access driver-private data
(which may be different from driver-core private data).

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

A virtualized display device is usually viewed with the vncviewer
application, either by 'xm vnc domU' or with vncviewer localhost:port.
vncviewer and the RFB protocol provides absolute coordinates to the
virtual display. These coordinates are either passed through to a PV
guest or converted to relative coordinates for a HVM guest.
A PV guest receives these coordinates and passes them to the kernels
evdev driver. There it can be picked up by applications such as the
xorg-input drivers. Using absolute coordinates avoids issues such as
guest mouse pointer not tracking host mouse pointer due to wrong mouse
acceleration settings in the guests X display.
Advertise either absolute or relative coordinates to the input system
and the evdev driver, depending on what dom0 provides. The xorg-input
driver prefers relative coordinates even if a devices provides both.
