commit 49e6979e7e92cf496105b5636f1df0ac17c159c0 upstream. trackpoint_detect() should be static inline while CONFIG_MOUSE_PS2_TRACKPOINT is not set, otherwise, we build fails: drivers/input/mouse/alps.o: In function `trackpoint_detect': alps.c:(.text+0x8e00): multiple definition of `trackpoint_detect' drivers/input/mouse/psmouse-base.o:psmouse-base.c:(.text+0x1b50): first defined here Reported-by: Hulk Robot Fixes: 55e3d9224b60 ("Input: psmouse - allow disabing certain protocol extensions") Signed-off-by: YueHaibing Signed-off-by: Dmitry Torokhov Cc: Hui Wang Signed-off-by: Greg Kroah-Hartman

Input: trackpoint - only expose supported controls for Elan, ALPS and NXP

2018-01-31T13:03:42+00:00

commit 2a924d71794c530e55e73d0ce2cc77233307eaa9 upstream. 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: trackpoint - add new trackpoint firmware ID

2017-08-19T00:04:11+00:00

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: psmouse - expose drift duration for IBM trackpoints

2014-12-17T23:46:51+00:00

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

2013-04-19T16:05:44+00:00

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. Signed-off-by: Shawn Nematbakhsh Signed-off-by: Dmitry Torokhov

Input: psmouse - allow disabing certain protocol extensions

2007-03-10T06:39:54+00:00

Allow ALPS, LOGIPS2PP, LIFEBOOK, TRACKPOINT and TOUCHKIT protocol extensions of psmouse to be disabled during compilation. This will allow users save some memory when they are sure that they will only use a certain type of mice. Signed-off-by: Andres Salomon Signed-off-by: Dmitry Torokhov
