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: trackpoint - assume 3 buttons when buttons detection fails

2017-07-19T00:28:47+00:00

Trackpoint buttons detection fails on ThinkPad 570 and 470 series, this makes the middle button of the trackpoint to not being recogized. As I don't believe there is any trackpoint with less than 3 buttons this patch just assumes three buttons when the extended button information read fails.

Merge tag 'v4.10-rc5' into next

2017-01-24T20:37:43+00:00

Sync up with mainline to bring up improvements in various subsystems.

Input: mouse - use local variables consistently

2017-01-22T07:52:22+00:00

If a function declares a variable to access a structure element, use it consistently. Signed-off-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Replace with globally

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

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: add missing POINTER / DIRECT properties to a bunch of drivers

2014-09-08T21:58:12+00:00

I've not done a full audit of all mouse drivers, I noticed these ones were missing the POINTER property while working on the POINTING_STICK property. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: add INPUT_PROP_POINTING_STICK property

2014-09-08T21:58:11+00:00

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.

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
