linux-toradex.git/drivers/input/mouse/trackpoint.c, branch v4.13-rc5

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.

Replace with globally

2016-12-24T19:46:01+00:00

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.

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.

Input: convert obsolete strict_strtox to kstrtox

2011-11-10T05:23:26+00:00

With commit 67d0a0754455f89ef3946946159d8ec9e45ce33a we mark strict_strtox
as obsolete. Convert all remaining such uses in drivers/input/.

Also change long to appropriate types, and return error conditions
from kstrtox separately, as Dmitry sugguests.

Input: return -ENOMEM in select drivers when memory allocation fails

Instead of using -1 let's start using proper error codes.
