Input: psmouse - use psmouse_[de]activate() from sentelic and hgpk drivers

2012-02-24T08:55:33+00:00

Make use of psmouse_activate() and psmouse_deactivate() from psmouse-base.c Signed-off-by: Andres Salomon Signed-off-by: Dmitry Torokhov

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. Signed-off-by: JJ Ding Signed-off-by: Dmitry Torokhov

Input: psmouse - switch to using dev_*() for messages

2011-10-11T01:28:16+00:00

This will ensure our reporting is consistent with the rest of the system and we do not refer to obsolete source file names. Reviewed-by: Wanlong Gao Reviewed-by: JJ Ding Reviewed-by: Daniel Kurtz Signed-off-by: Dmitry Torokhov

Input: psmouse - hgpk.c needs module.h

2011-07-30T19:03:26+00:00

hgpk.c uses interfaces from linux/module.h, so it should include that file. This fixes build errors. Signed-off-by: Randy Dunlap Signed-off-by: Dmitry Torokhov

Input: hgpk - fix powersave mode

2010-11-15T09:33:59+00:00

Recent testing of this codepath showed that it wasn't working, perhaps due to changes within the input layer. This fixes it. Signed-off-by: Daniel Drake Signed-off-by: Dmitry Torokhov

Input: hgpk - recalibration tweaks

2010-11-15T09:33:51+00:00

Disable the recalibration guard where new recalibrations are triggered if we detect a packet too soon after calibrating - we found that this results in erroneous recalibrations, and if the recalibration failed then the rest of our badness-detection code will request another. Add a module option disabling all of the recalibration code, in case an OLPC deployment thinks all of the workarounds we have are doing more damage than good and wants to experiment with them all disabled. Based on work by Paul Fox. Signed-off-by: Daniel Drake Signed-off-by: Dmitry Torokhov

Input: hgpk - extend jumpiness detection

2010-11-12T06:21:24+00:00

In addition to forcing recalibrations upon detection of cursor jumps (and performing them quicker than before), detect and discard errant 'jump' packets caused by a firmware bug, which are then repeated with each one being approximately half the delta of the one previously (as if it is averaging out) Based on original work by Paul Fox.

Input: hgpk - rework spew detection

2010-11-12T06:21:19+00:00

The old implementation of spew detection simply tracked the overall position delta of the cursor over every 100 packets. We found that this causes occasional false positives in spew detection, and also that the conditions of the spewy packets are perhaps more fixed than we once thought. Rework the spew detection to look for packets of specific small delta, and only recalibrating if the overall movement delta stays within expected bounds. Also discard duplicate packets in the advanced mode, which appear to be very common. If we don't, the spew detection kicks in far too early. If we get a large spew of duplicates, request a recalibration straight up. Based on earlier work by Paul Fox. Signed-off-by: Daniel Drake Signed-off-by: Dmitry Torokhov
