Subject: [PATCH v3 7/8] HID: logitech: Enable high-resolution scrolling on Logitech mice
Date: Wed,  5 Dec 2018 10:42:27 +1000
Message-ID: <20181205004228.10714-8-peter.hutterer@who-t.net> (raw)
In-Reply-To: <20181205004228.10714-1-peter.hutterer@who-t.net>

From: Harry Cutts <hcutts@chromium.org>

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.

Changes to v1:
- get rid of the timer in favour of sched_clock()
- drop storing the multiplier and calculate value on the fly

Changes to v2:
- m560 now has REL_HWHEEL_HI_RES (untested, I don't have the device)
