PATCH [0/3] input: xpad.c - Xbox 360 wireless and sysfs support

[Mike Murphy <mamurph@cs.clemson.edu>]

Greetings,

This patchset improves the in-kernel xpad.c driver by improving
support for the Xbox 360 wireless controllers, and by adding a number
of features that can be controlled via a new sysfs interface. Rumble
is now enabled on the wireless 360 controllers, and the LED display is
set properly instead of flashing constantly. New features include
implementation of a dead zone for the analog sticks, ability to map
the stick inputs onto a square axis, ability to turn rumble off on a
per-controller basis, and a mechanism for identifying the controller
type and (presumably) unique ID of wireless controllers. In addition,
and as a change to the most recent development patch, I have adjusted
the triggers so that they both implement half-axes instead of full
axes. In other words, they report a range from 0 to +32767, instead of
-32767 to +32767. This change improves behavior on some gaming
emulators, and it can be turned off via the sysfs interface.

In addition to the core patch, I have updated
Documentation/input/xpad.txt, and I have added
Documentation/ABI/testing/game_device-sysfs-interface to document the
added sysfs interface. I'd like to thank Oliver Neukum, Greg
Kroah-Hartman, and Frederic Weisbecker for their helpful feedback
during the development process.

Thanks,
Mike
