Nicolas Léveillé b45d44e7e0 Input: xpad - allow using triggers as buttons rather than axes 
Certain devices implement triggers as buttons rather than axes. In
particular, arcade sticks such as the HORI Real Arcade Pro.EX do not
have analog buttons.

These devices are now setup to present buttons rather than axes for
triggers.

User-space applications often also have problems with
axes-as-buttons. Activating MAP_TRIGGERS_TO_BUTTONS for a device
removes the artificial difference between buttons and triggers.

* This driver is based on:
* - information from http://euc.jp/periphs/xbox-controller.ja.html
* - the iForce driver drivers/char/joystick/iforce.c
* - the skeleton-driver drivers/usb/usb-skeleton.c
* - Xbox 360 information http://www.free60.org/wiki/Gamepad
*
* Thanks to:
* - ITO Takayuki for providing essential xpad information on his website
* - Vojtech Pavlik - iforce driver / input subsystem
* - Greg Kroah-Hartman - usb-skeleton driver
* - XBOX Linux project - extra USB id's
*
* TODO:
* - fine tune axes (especially trigger axes)
* - fix "analog" buttons (reported as digital now)
* - get rumble working
* - need USB IDs for other dance pads
*
* History:
*
* 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
*
* 2002-07-02 - 0.0.2 : basic working version
* - all axes and 9 of the 10 buttons work (german InterAct device)
* - the black button does not work
*
* 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
* - indentation fixes
* - usb + input init sequence fixes
*
* 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
* - verified the lack of HID and report descriptors
* - verified that ALL buttons WORK
* - fixed d-pad to axes mapping
*
* 2002-07-17 - 0.0.5 : simplified d-pad handling
*
* 2004-10-02 - 0.0.6 : DDR pad support
* - borrowed from the XBOX linux kernel
* - USB id's for commonly used dance pads are present
* - dance pads will map D-PAD to buttons, not axes
* - pass the module paramater 'dpad_to_buttons' to force
* the D-PAD to map to buttons if your pad is not detected
*
* Later changes can be tracked in SCM.
