HID: logitech: Enable high-resolution scrolling on Logitech mice

2018-12-07T15:27:15+00:00

There are three features used by various Logitech mice for
high-resolution scrolling: the scrolling acceleration bit in HID++ 1.0,
and the x2120 and x2121 features in HID++ 2.0 and above. This patch
supports all three, and uses the multiplier reported by the mouse for
the HID++ 2.0+ features.

The full list of product IDs of mice which support high-resolution
scrolling was provided by Logitech, but the patch was tested using the
following mice (using the Unifying receiver):

* HID++ 1.0: Anywhere MX, Performance MX
* x2120: M560
* x2121: MX Anywhere 2, MX Master 2S

This patch is a combinations of the now-reverted commits 1ff2e1a44e0,
d56ca9855bf9, 5fe2ccbef9d, 044ee89028 together with some extra bits for the
directional and timeout-based reset.
The previous patch series was in hid-input, it appears this remainder
handling is logitech-specific and was moved to hid-logitech-hidpp.c and
renamed accordingly.

HID: logitech: Add function to enable HID++ 1.0 "scrolling acceleration"

2018-12-07T15:27:15+00:00

"Scrolling acceleration" is a bit of a misnomer: it doesn't deal with
acceleration at all. However, that's the name used in Logitech's spec,
so I used it here.

This reverts commit 051dc9b0579602bd63e9df74d0879b5293e71581.

It turns out the current API is not that compatible with
some Microsoft mice, so better start again from scratch.
