HID: wiimote: support Nintendo Wii U Pro Controller
The Wii U Pro Controller is a new Nintendo remote device that looks very similar to the XBox controller. It has nearly the same features and uses the same protocol as the Wii Remote. We add a new wiimote extension device so the Pro Controller is properly detected and supported. The device reports MP support, which is odd and I couldn't get it working, yet. Hence, we disable MP registers for now. Further investigation is needed to see what extra capabilities are provided. There are some other unknown bits in the extension reports that I couldn't figure out what they do. You can use hidraw to access these if you're interested. We might want to hook up the "charging" and "USB" bits to the battery device so user-space can query whether it is currently charged via USB. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
