Input: trackpoint - add new trackpoint firmware ID 2017-11-11T13:33:23+00:00 Aaron Ma aaron.ma@canonical.com 2017-08-18T19:17:21+00:00 1eeac6efe7339a3cefa4ee7a804344194b7ad85a commit ec667683c532c93fb41e100e5d61a518971060e2 upstream. Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits are indicated as TP. Change the constant to bitwise values. This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead of it being identified as "PS/2 Generic Mouse".

Input: trackpoint - Optimize trackpoint init to use power-on reset 2013-04-19T16:05:44+00:00 Shawn Nematbakhsh shawnn@chromium.org 2013-04-15T20:49:34+00:00 0c6a61657da78098472fd0eb71cc01f2387fa1bb The trackpoint driver sets various parameter default values, all of which happen to be power-on defaults (Source: IBM TrackPoint Engineering Specification, Version 4.0. Also confirmed by empirical data). By sending the power-on reset command to reset all parameters to power-on state, we can skip the lengthy process of programming all parameters. In testing, ~2.5 secs of time writing parameters was reduced to .35 seconds waiting for power-on reset to complete.
