Subject[PATCH v2 0/5] Add support for high-resolution scrolling on Logitech mice
Hi everyone,

This is v2 of the patch set adding support for high-resolution scroll
wheels on Logitech mice. See the linux-input "Reporting high-resolution
scroll events" thread [0] for previous discussion of the evdev changes.
I would love to hear your feedback.


Harry Cutts
Chrome OS Touch/Input team


Changes in v2:
* Changed the REL_WHEEL_HI_RES code to use micrometres (a.k.a. microns)
as its units, instead of 256ths of a millimetre.
* Removed support for mice connecting over Bluetooth, due to a bug where
the mouse's high-res mode and the driver's settings get out of sync
when the mouse is power cycled.
* Moved the creation of the HID++ 1.0 function and the refactor to use
the LDJ_DEVICE macro into separate patches.
* Added a couple of explanatory comments to the Logitech driver.

Harry Cutts (5):
Add the `REL_WHEEL_HI_RES` event code
Create a utility class for counting scroll events
Add function to enable HID++ 1.0 "scrolling acceleration"
Enable high-resolution scrolling on Logitech mice
Use LDJ_DEVICE macro for existing Logitech mice
