[PATCH 0/4] input: add support for high resolution wheel found on some Logitech devices

[Mauro Carvalho Chehab <mchehab@s-opensource.com>]

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.

PS.: this patch series come after a patch series I sent during the weekend,
with converts the input documentation to ReST format:
