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.
Tested on with MX Anywhere 2 device.
PS.:
Patches 2 and 3 will have trivial conflicts with -next version of the
input tree, due to the documentation patches that got merged there.
v4:
- rebased on the top of HID tree, branch 'for-next'
- added a patch reserving some REL_MISC_n events
- fixed CMD_MOUSE_SET_WHEEL_MODE params logic;
- don't send 16 bytes on FAP command sync - send just what's needed;
- HIDPP_QUIRK_CONNECT_EVENTS is now applied by default.
v3: addressed Peter's comments for EV_SW SW_RATCHET documentation
Mauro Carvalho Chehab (5):
input: event-codes: reserve some space for REL_MISC events
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
