Some Logitech mouses (MX Anyware 2, MX Master) have a wheel with two resolutions. It initializes in low resolution mode, but can be changed to high resolution. It also supports free wheel mode, where there's no tactile feedback at the wheel, nor it offers resistence to movements. Such mode is enabled/disabled by clicking at the wheel (on this wheel, the middle button is a separate button). Add support for it. v3: addressed Peter's comments for EV_SW SW_RATCHET documentation Mauro Carvalho Chehab (4): input: add an EV_REL event for high-res vertical wheel input: add a EV_SW event for ratchet switch hid-logitech-hidpp: add support for high res wheel hid-logitech-hidpp: add support for ratchet switch Documentation/input/event-codes.rst | 28 ++++- drivers/hid/hid-logitech-hidpp.c | 218 +++++++++++++++++++++++++++++++++ include/linux/mod_devicetable.h | 2 +- include/uapi/linux/input-event-codes.h | 5 +- 4 files changed, 248 insertions(+), 5 deletions(-) -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
