[PATCH 0/2] Input: ABS2 and motion tracking

[Roderick Colenbrander <roderick@gaikai.com>]

From: Roderick Colenbrander <roderick.colenbrander@sony.com>

For some input driver work we have been doing, we were limited by not
having a wide enough ABS range in evdev. The current ABS range is mostly
full and due to limitations on the ioctl design, it can't be extended.

About 3 years ago, David Herrmann did work in this area to address this
problem for similar reasons as us. However his patches at the time didn't
make it in.

Since we have a need for this kind of functionality, we took over his
patches and are submitting them again with various improvements based
on feedback to the original patches and some new functionality for motion
tracking we are interested in ourselves. The patchset is simpler than before,
because at the time a uinput overhaul was needed, before uinput could even
support ABS_MAX2, which has happened since then.

The patches have been tested with some David's libevdev branch which
supports the new APIs. In addition we verified the new APIs in some
of internal software.

Thanks,
