2011-07-25Input: synaptics - fix reporting of min coordinatesDmitry Torokhov
We were testing wrong bit in the extended capability query. Reported-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-07-09Input: synaptics - set minimum coordinates as reported by firmwareDmitry Torokhov
Newer Synaptics firmware allows to query minimum coordinates reported by the device, let's use this data. Acked-by: Chase Douglas <chase.douglas@canonical.com> Acked-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2011-07-06Input: synaptics - fuzz position for touchpad with reduced filteringDaniel Kurtz
Synaptics touchpads indicate via a capability bit when they perform reduced filtering on position data. In such a case, use a non-zero fuzz value. Fuzz = 8 was chosen empirically by observing the raw position data reported by a clickpad indicating it had reduced filtering.

2011-02-23Input: synaptics - document 0x0c queryDmitry Torokhov
Since Synaptics technical writers department is a bit slow releasing updated Synaptics interface guide, let's add some new bits (with their blessing) to the code so that they don't get lost. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-12-21Input: synaptics - add multi-finger and semi-mt supportHenrik Rydberg
The Synaptics 2.7 series of touchpads support a mode for reporting two sets of X/Y/Pressure data (advanced gesture mode). By default, these devices report only single finger data, depriving userspace of the nowadays ubiquitous two-finger scroll gesture. Enabling advanced gesture mode also enables the multi-finger report, although the device does not claim that capability. Up to three fingers can be reported this way. While two or three fingers are touching, the normal packet is prepended by a reduced finger packet of lower resolution. From the two packets (which do not represent the actual fingers), the bounding rectangle of the individual contacts can be extracted. This information is sufficient to perform scaling gestures and a limited form of rotation gesture. The behavior has been coined semi-mt capability, and is signaled to userspace via the INPUT_PROP_SEMI_MT device property. Work to decode the advanced gesture packet: Takashi Iwai. Cleanup and testing of the original patch: Chase Douglas. Minor cleanup and testing: Chris Bagwell. Finalization and semi-mt support: Henrik Rydberg.

2010-11-30Input: synaptics - fix handling of 2-button ClickPadsYan Li
Lenovo S10-3t's ClickPad is a 2-button ClickPad that reports BTN_LEFT and BTN_RIGHT as normal touchpad, unlike the 1-button ClickPad used in HP mini 210 that reports solely BTN_MIDDLE. In 0xc0-cap response, the 1-button ClickPad has the 20-bit set while 2-button ClickPad has the 8-bit set. This patch makes the kernel only handle 1-button ClickPad specially, and treat 2-button ClickPad in the same fashion as regular touchpads. This fixes kernel bug #18122 and MeeGo bug #4807.

There was too much knowledge about internals if serio in the pass-through handling, clean it up. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-07-21Input: synaptics - relax capability ID checks on newer hardwareDmitry Torokhov
Older firmwares fixed the middle byte of the Synaptics capabilities query to 0x47, but starting with firmware 7.5 the middle byte represents submodel ID, sometimes also called "dash number". Reported-and-tested-by: Miroslav Šulc <fordfrog@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-05-19Input: synaptics - set dimensions as reported by firmwareDmitry Torokhov
Newer Synaptics firmware allows to query maximim dimensions reported by device, let's use this data. Tested-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-04-20Input: Add support of Synaptics Clickpad deviceTakashi Iwai
The new type of touchpads can be detected via a new query command 0x0c. The clickpad flags are in cap[0]:4 and cap[1]:0 bits. When the device is detected, the driver now reports only the left button as the supported buttons so that X11 driver can detect that the device is Clickpad. A Clickpad device gives the button events only as the middle button. The kernel driver morphs to the left button. The real handling of Clickpad is done rather in X driver side.

2010-01-07Input: psmouse - fix Synaptics detection when protocol is disabledDaniel Drake
For configurations where Synaptics hardware is present but the Synaptics extensions support is not compiled in, the mouse is reprobed and a new device is allocated on every suspend/resume. During probe, psmouse_switch_protocol() calls psmouse_extensions() with set_properties=1. This calls the dummy synaptics_init() which returns an error code, instructing us not to use the synaptics extensions. During resume, psmouse_reconnect() calls psmouse_extensions() with set_properties=0, in which case call to synaptics_init() is bypassed and PSMOUSE_SYNAPTICS is returned. Since the result is different from previous attempt psmouse_reconnect() fails and full re-probe happens. Fix this by tweaking the set_properties=0 codepath in psmouse_extensions() to be more careful about offering PSMOUSE_SYNAPTICS extensions.

DMI tables use considerable amount of memory. Mark them as __initconst so they will be discarded once module is loaded. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2009-06-19Input: synaptics - add support for reporting x/y resolutionTero Saarni
Synaptics uses anisotropic coordinate system. On some wide touchpads vertical resolution can be twice as high as horizontal which causes unequal sensitivity on x/y directions. Add support for reading the resolution with EVIOCGABS ioctl. Signed-off-by: Tero Saarni <tero.saarni@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2007-03-10Input: psmouse - allow disabing certain protocol extensionsAndres Salomon
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.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
