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 commits1ff2e1a44e,d56ca9855b,5fe2ccbef9,044ee89028together 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
