From d4bdf2d2ba737c2c02ec014bdc2db40a030595d0 Mon Sep 17 00:00:00 2001 From: Nicolas Adenis-Lamarre Date: Wed, 20 Jun 2018 12:55:15 +0200 Subject: HID: wiimote: add support for Guitar-Hero devices This adds the drums and guitar extensions for Wiimote devices. Devices are reported as "Nintendo Wii Remote Guitar/Drums". If I ever get my hands on "RockBand" guitars, I will try to report them via the same interface so user-space does not have to bother which device it deals with. This is a rebase of the original commits 8e22ecb603c8 and 73f8645db191. They were reverted several years ago, since they were dependent on the ABS_* rework of the input core. Sadly, this never worked out so these commits were never pushed into a release. This rebase now uses the ABS_HAT* event codes to report all pressure information.
