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.

There are two types of 1FGT devices supported in wacom_wac.c.
Changing them to follow the existing touchscreen format, i.e.,
only report BTN_TOUCH as a valid tool type.
Touch data will be ignored if pen is in proximity. This requires
a touch up event sent if touch was down when pen comes in. The
touch up event should be sent before any pen events are emitted.
Otherwise, two pointers would race for the cursor.
However, we can not send a touch up inside wacom_tpc_pen since
pen and touch are on different logical port. That is why we
have to check if touch is up before sending pen events.

The mxt_check_matrix_size() is currently setting the CTE mode to match
xline/yline information that is in the platform data, but it does not
take into account for example the fact that we could have a key array
in use too (key array would use some x/y lines as well).
It would be better to simply rely on the configuration data, and make
sure that the CTE mode set in there matches the touch object (touchscreen,
key array, proximity) configuration (which are set in the config data too).

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.
