15 * This driver is based on:
16 *  - information from     http://euc.jp/periphs/xbox-controller.ja.html
17 *  - the iForce driver    drivers/char/joystick/iforce.c
18 *  - the skeleton-driver  drivers/usb/usb-skeleton.c
19 *  - Xbox 360 information http://www.free60.org/wiki/Gamepad
20 *  - Xbox One information https://github.com/quantus/xbox-one-controller-protocol
21 *
22 * Thanks to:
23 *  - ITO Takayuki for providing essential xpad information on his website
24 *  - Vojtech Pavlik     - iforce driver / input subsystem
25 *  - Greg Kroah-Hartman - usb-skeleton driver
26 *  - XBOX Linux project - extra USB id's
27 *  - Pekka Pöyry (quantus) - Xbox One controller reverse engineering
28 *
29 * TODO:
30 *  - fine tune axes (especially trigger axes)
31 *  - fix "analog" buttons (reported as digital now)
32 *  - get rumble working
33 *  - need USB IDs for other dance pads
34 *
35 * History:
36 *
37 * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
38 *
39 * 2002-07-02 - 0.0.2 : basic working version
40 *  - all axes and 9 of the 10 buttons work (german InterAct device)
41 *  - the black button does not work
42 *
43 * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
44 *  - indentation fixes
45 *  - usb + input init sequence fixes
46 *
47 * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
48 *  - verified the lack of HID and report descriptors
49 *  - verified that ALL buttons WORK
50 *  - fixed d-pad to axes mapping
51 *
52 * 2002-07-17 - 0.0.5 : simplified d-pad handling
53 *
54 * 2004-10-02 - 0.0.6 : DDR pad support
55 *  - borrowed from the XBOX linux kernel
56 *  - USB id's for commonly used dance pads are present
57 *  - dance pads will map D-PAD to buttons, not axes
58 *  - pass the module paramater 'dpad_to_buttons' to force
59 *    the D-PAD to map to buttons if your pad is not detected
60 *
61 * Later changes can be tracked in SCM.
