3 * Device Modules for Nintendo Wii / Wii U HID Driver
4 * Copyright (c) 2011-2013 David Herrmann <dh.herrmann@gmail.com>
12 * Nintendo devices provide different peripherals and many new devices lack
13 * initial features like the IR camera. Therefore, each peripheral device is
14 * implemented as an independent module and we probe on each device only the
15 * modules for the hardware that really is available.
17 * Module registration is sequential. Unregistration is done in reverse order.
18 * After device detection, the needed modules are loaded. Users can trigger
19 * re-detection which causes all modules to be unloaded and then reload the
20 * modules for the new detected device.
22 * wdata->input is a shared input device. It is always initialized prior to
23 * module registration. If at least one registered module is marked as
24 * WIIMOD_FLAG_INPUT, then the input device will get registered after all
25 * modules were registered.
26 * Please note that it is unregistered _before_ the "remove" callbacks are
27 * called. This guarantees that no input interaction is done, anymore. However,
28 * the wiimote core keeps a reference to the input device so it is freed only
29 * after all modules were removed. It is safe to send events to unregistered

41 * The initial Wii Remote provided a bunch of buttons that are reported as
42 * part of the core protocol. Many later devices dropped these and report
43 * invalid data in the core button reports. Load this only on devices which
44 * correctly send button reports.
45 * It uses the shared input device.

2506 * roation is 8192/440 units / deg/s and for fast rotation 8192/2000
2507 * units / deg/s. To get a linear scale for fast rotation we multiply
2508 * by 2000/440 = ~4.5454 and scale both fast and slow by 9 to match the
2509 * previous scale reported by this driver.
2510 * This leaves a linear scale with 8192*9/440 (~167.564) units / deg/s.
2511 * If the wiimote is not rotating the sensor reports 2^13 = 8192.
2512 * Ext specifies whether an extension is connected to the motionp.
2513 * which is parsed by wiimote-core.
