Currently there are only two "tools" that can be specified by a multi-touch
driver: MT_TOOL_FINGER and MT_TOOL_PEN. In working with Elan (The touch
vendor) and discussing their next-gen devices it seems that it will be
useful to have more tools so that their devices can give the upper layers
of the stack hints as to what is touching the sensor.In particular they have new experimental firmware that can better
differentiate between palms vs fingertips and would like to plumb a patch
so that we can use their hints in higher-level gesture soft- ware. The
firmware on the device can reasonably do a better job of palm detection
because it has access to all of the raw sensor readings as opposed to just
the width/pressure/etc that are exposed by the driver. As such, the
firmware can characterize what a palm looks like in much finer-grained
detail and this change would allow such a device to share its findings with
the kernel.Signed-off-by: Charlie Mooney

This is effectively already in force through input_mt_init_slots, and uinput
too ignores the actual minimum.Since slots are a kernel-genenerated axis only, non-zero minimums make
little sense and are likely to cause errors. Better to treat a non-zero
minimum as kernel bug if it ever happens.Signed-off-by: Peter Hutterer

The newly released HID protocol for win8 multitouch devices is capable
of transmitting more information about each touch. In particular, it
includes details useful for touch alignment. This patch completes the
MT protocol with the ABS_MT_TOOL_X/Y events, and documents how to map
win8 devices.Cc: Stephane Chatty

Some devices are capable of identifying and/or tracking more contacts than
they can report to the driver. Document how a driver should handle this,

Touch devices capable of hovering, i.e., fingers detected a
distance from the surface, are not supported by the current
input MT protocol. This patch adds ABS_MT_DISTANCE, which may
be used to indicate the distance between the contact and the
surface.Signed-off-by: Henrik Rydberg

The current documentation does not explicitly specify how to report
zero fingers, leaving a potential problem in the driver implementations
and giving no parsing directive to userland. This patch defines two
