Input: trackpoint - only expose supported controls for Elan, ALPS and NXP The newer trackpoints from ALPS, Elan and NXP implement a very limited subset of extended commands and controls that the original trackpoints implemented, so we should not be exposing not working controls in sysfs. The newer trackpoints also do not implement "Power On Reset" or "Read Extended Button Status", so we should not be using these commands during initialization. While we are at it, let's change "unsigned char" to u8 for byte data or bool for booleans and use better suited error codes instead of -1.

Input: psmouse - expose drift duration for IBM trackpoints IBM Trackpoints have a feature to compensate for drift by recalibrating themselves periodically. By default, if for 0.5 seconds there is no change in position, it's used as the new zero. This duration is too low. Often, the calibration happens when the trackpoint is in fact being used. IBM's Trackpoint Engineering Specifications show a configuration register that allows changing this duration, rstdft1. Expose it via sysfs among the other settings.

Input: trackpoint - Optimize trackpoint init to use power-on reset 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.
