HID: wiimote: Add support for the DJ Hero turntable
This adds support for the turntable extension for Wiimote devices. jstest-gtk and html5 gamepad tester show everything correctly but when trying to map the controller in software like rpcs3 or dolphin it currently doesn't map correctly Co-authored-by: Bogdan Petru <thonkdifferent@outlook.com> Signed-off-by: Bogdan Petru <thonkdifferent@outlook.com> Signed-off-by: Joshua Jun <joshuajun@vivaldi.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
