 * 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
 *  - Xbox One information https://github.com/quantus/xbox-one-controller-protocol
 *
 * 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
 *  - Pekka Pöyry (quantus) - Xbox One controller reverse engineering
 *
 * 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.
