From 7611392fe8ff95ecae528b01a815ae3d72ca6b95 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 8 Sep 2014 14:42:12 -0700 Subject: Input: add INPUT_PROP_POINTING_STICK property It is useful for userspace to know that there not dealing with a regular mouse but rather with a pointing stick (e.g. a trackpoint) so that userspace can e.g. automatically enable middle button scrollwheel emulation. It is impossible to tell the difference from the evdev info without resorting to putting a list of device / driver names in userspace, this is undesirable. Add a property which allows userspace to see if a device is a pointing stick, and set it on all the pointing stick drivers.
