Currently, the pad events are sent through the stylus input device
for the Intuos/Cintiqs, and through the touch input device for the
Bamboos.
To differentiate the buttons pressed on the pad from the ones pressed
on the stylus, the Intuos/Cintiq uses MISC_SERIAL and ABS_MISC. This
lead to a multiplexing of the events into one device, which are then
splitted out in xf86-input-wacom. Bamboos are not using MISC events
because the pad is attached to the touch interface, and only BTN_TOUCH
is used for the finger (and DOUBLE_TAP, etc...). However, the user space
driver still splits out the pad from the touch interface in the same
way it does for the pro line devices.
The other problem we can see with this fact is that some of the Intuos
and Cintiq have a wheel, and the effective range of the reported values
is [0..71]. Unfortunately, the airbrush stylus also sends wheel events
(there is a small wheel on it), but in the range [0..1023]. From the user
space point of view it is kind of difficult to understand that because
the wheel on the pad are quite common, while the airbrush tool is not.
A solution to fix all of these problems is to split out the pad device
from the stylus/touch. This decision makes more sense because the pad is
not linked to the absolute position of the finger or pen, and usually, the
events from the pad are filtered out by the compositor, which then convert
them into actions or keyboard shortcuts.
For backward compatibility with current xf86-input-wacom, the pad devices
still present the ABS_X, ABS_Y and ABS_MISC events, but they can be
completely ignored in the new implementation.

This patch adds support for the 0x4004, 0x5000, and 0x5002 sensors found
on what should be the Motion R12, Fujitsu Q704, and Fujitsu T904. These
tablets use a new report ID (3) for their touch packets and a slightly
different HID descriptor format, but are otherwise largely identical in
protocol to the "MTTPC" tablets.
Note:
* The R12 uses its 0x4004 sensor for touch input only. A pen interface
is not present in its HID descriptor, though its possible a 0x4004
may be used for pen input by other tablet PCs in the future.
* The 0x5002 sensor appears to use a new report ID (8) for its pen
packets. The other sensors continue to use the traditional report
ID (2).

The EMR sensor of Intuos4 and newer devices can send a packet with
0x20 in its second byte which contains only location information.
This packet is sent when the pen is too far away to reliably obtain
other information. Because only the location is updated userspace
will continue to see stale information for other values, most notably
TOUCH, PRESSURE, and DISTANCE.
This patch ensures userspace is not left with stale device state
information when the pen re-enters proximity (possibly leading to
the assumption the pen is still in contact even though it is
actually hovering).

Henrik added new MT routines in release 3.7. This patch is to prepare
for the use of new MT routines.
In the newly added wacom_abs_set_axis() function, the first
if-statement assigns ABS_X/Y for number of contacts less or equal
to 2. So, it is single and 2 finger touch devices. Two finger touch
devices are processed here since they will not use the updated
input_mt_init_slots(), which does not offer benefit to those devices.
input_mt_init_slots() will take care of ABS_X/Y assignment when flags
are not zero. All touch devices with more than two contacts will use
input_mt_init_slots() with non-zero flags.
The second if-statement is for all MT devices, which include two
finger touch devices.

Like our other pen-and-touch products, the Cintiq 24HD touch needs data
to be shared between its two sensors to facilitate proximity-based palm
rejection.
Unlike other tablets that report sensor data through separate interfaces
of the same USB device, the Cintiq 24HD touch has separate USB devices
that are connected to an internal USB hub.
This patch makes it possible to designate the USB VID/PID of the other
device so that the two may share data. To ensure we don't accidentally
link to a sensor from a physically separate device (if several have been
plugged in), we limit the search to siblings (i.e., devices directly
connected to the same hub).
