This driver supports Synaptics I2C touchpad controller on eXeda
mobile device. Unfortunaltely it only works in relative mode and
thus is not comaptible with Xorg Synaptics driver.

Synaptics uses anisotropic coordinate system. On some wide touchpads
vertical resolution can be twice as high as horizontal which causes
unequal sensitivity on x/y directions. Add support for reading the
resolution with EVIOCGABS ioctl.

When pressing any button belonging to the touchpoint, the generated
click events don't belong to the touchpoint but to the touchpad.
This patch fixes this behaviour, the events will be sent via the
correct device, so scrolling with touchpoint is possible.

The appletouch driver is prone to reporting multiple fingers when only
one is pressing. The appletouch driver queries an array of pressure
sensors and counts local maxima in pressure to determine the number of
fingers. It just does this on the raw values, so a data stream like:
0 100 250 300 299 300 250 100 0
actually registers as 2 fingers.
This patch updates the logic to ignore small dips in pressure that are
less than the threshold.

It appears that when the XO touchpad unit resets from ESD, it sends AA
AA instead of AA 00, the psmouse-base code handles the case of AA 00 by
triggering a serio reconnect for the port, causing a full reprobe of
the device.
Testing with OFW shows that this is likely to solve the problem, so
the attached patch simply expands the existing test to also catch AA AA.

When we get a relative packet from trackpoint (when we deal with
touchscreen/trackpoint combo) we should not send events for the device
corresponding to touchscreen as it confuses evtouch driver (it looks
like it keeps previously reported absolute coordinates and the cursor
stays in the same place).

This patch adds support for the new unibody Macbook, with physically
integrated button and trackpad. Since the integrated button changes
the logic for touch-and-click, a device capability bit mask is now
reported in input_id.version, which can be picked up by user space
via a EVIOCGID call.

The integrated button on the new unibody Macbooks presents a need to
report explicit four-finger actions. Evidently, the finger pressing
the button is also touching the trackpad, so in order to fully support
three-finger actions, the driver must be able to report four-finger
actions. This patch adds a new button, BTN_TOOL_QUADTAP, which
achieves this.

There exist laptops with Elantech touchpads where switching to absolute mode
does not happen, although writing the configuration register succeeds
without error. Reading back the register afterwards reveils that the
absolute mode bit is not set as if masked out by the touchpad firmware.
Always read back register 0x10, make sure that for hardware version 1 the
absolute mode bit is actually set and fail otherwise. This prevents the case
where the touchpad is claimed by the Elantech driver but is nonetheless not
working.

It seems that Elantech touchpad firmware version 2.34 on the Hercules eCAFÉ
suffers from a problem where bogus coordinates get reported at the beginning
of a touch action. This causes the mouse cursor or the scrolled page to
jump.
Included patch provides a workaround that discards mouse packets that are
likely to contain bogus coordinates. The workaround is activated when we
detect touchpad with fimware version 2.34.

It is a fairly common operation to have a pointer to a work and to need a
pointer to the delayed work it is contained in. In particular, all
delayed works which want to rearm themselves will have to do that. So it
would seem fair to offer a helper function for this operation.
