There are a bunch of guitar and drums devices out there that all report similar data. To avoid reporting this as BTN_MISC or ABS_MISC, we allocate some proper namespace for them. Note that most of these devices are toys and we cannot report any sophisticated physics via this API. I did some google-images research and tried to provide definitions that work with all common devices. That's why I went with 4 toms, 4 cymbals, one bass, one hi-hat. I haven't seen other drums and I doubt that we need any additions to that. Anyway, the naming-scheme is intentionally done in an extensible way. For guitars, we support 5 frets (normally aligned vertically, compared to the real horizontal layouts), a single strum-bar with up/down directions, an optional fret-board and a whammy-bar. Most of the devices provide pressure values so I went with ABS_* bits. If we ever support devices which only provide digital input, we have to decide whether to emulate pressure data or add additional BTN_* bits. If someone is not familiar with these devices, here are two pictures which provide almost all introduced interfaces (or try the given keywords with a google-image search): Guitar: ("guitar hero world tour guitar") http://images1.wikia.nocookie.net/__cb20120911023442/applezone/es/images/f/f9/Wii_Guitar.jpg Drums: ("guitar hero drums") http://oyster.ignimgs.com/franchises/images/03/55/35526_band-hero-drum-set-hands-on-20090929040735768.jpg Signed-off-by: David Herrmann <dh.herrmann@gmail.com> --- include/linux/mod_devicetable.h | 2 +- include/uapi/linux/input.h | 24 +++++++++++++++++++++++- 2 files changed, 24 insertions(+), 2 deletions(-)
