ThinkPad TrackPoint with libinput

[Monty Chaney-Geib]

I'm trying to get the scrolling working with my TrackPoint. I have
everything else working fine. I tired adding these options to my xorg
config, but it didn't seem to work.

Option    "Emulate3Buttons" "true"
Option    "EmulateWheel" "on"
Option    "EmulateWheelButton" "2"
Option    "YAxisMapping" "4 5"
Option    "XAxisMapping" "6 7"

Any help would be appreciated.
