The Wii Remote driver exposes three input devices for each connected Wii Remote: a main device for buttons and rumble, the accelorometer and the IR camera. Since the main device exposes a BTN_A, it is considered to be a gamepad from the input subsystem, and it gets handled as a joystick, accessible via the appropriate /dev/input/jsN device. However, since the input device itself does not expose any positional information, it appears as a joystick with no axes (and 7 buttons). The following two patches try to fix this problem by allowing buttons to also be exposed via the Accelerometer input device. This way this device also becomes a joystick, this time fully functional (three axes, 7 buttons). The patchset is marked as RFC because I'm not 100% satisfied with the solution. Although it does make the device usable as joystick in software that does not have support for it otherwise, it presents two problems: (1) button presses are reported twice, so one has to e.g. disable input from the main device in software that supports both keyboards and joysticks at the same time; (2) the main device is still reported as a gamepad and caught by the joydev driver. A possible solution (not yet implemented in this patchset) for issue #1 would be to have a control (accessible via e.g. the /sys interface) to select the device(s) for which the keys are reported. For issue #2 there are two possible solutions: an explicit blacklist of the the Wii Remote main device, or a fine-tuning of joydev_ids list. Suggestions and critism welcome.
