Input: synaptics - adjust min/max on Thinkpad E540

The LEN2006 Synaptics touchpad (as found in Thinkpad E540) returns wrong min max values. touchpad-edge-detector output: > Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event6 > Move one finger around the touchpad to detect the actual edges > Kernel says: x [1472..5674], y [1408..4684] > Touchpad sends: x [1264..5675], y [1171..4688] Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=88211 Cc: stable@vger.kernel.org Signed-off-by: Binyamin Sagal Signed-off-by: Dmitry Torokhov

Input: synaptics - add min/max quirk for Lenovo T440s

2014-11-06T18:05:52Z

The new Lenovo T440s laptop has a different PnP ID "LEN0039", and it needs the similar min/max quirk to make its clickpad working. BugLink: https://bugzilla.opensuse.org/show_bug.cgi?id=903748 Reported-and-tested-by: Joschi Brauchle Cc: Signed-off-by: Takashi Iwai Signed-off-by: Dmitry Torokhov

Input: synaptics - gate forcepad support by DMI check

2014-10-11T18:34:42Z

Unfortunately, ForcePad capability is not actually exported over PS/2, so we have to resort to DMI checks. Cc: stable@vger.kernel.org Reported-by: Nicole Faerber Signed-off-by: Dmitry Torokhov

Merge tag 'v3.17' into next

Synchronize with mainline to bring in changes to Synaptics and i8042 drivers.

Input: psmouse - add psmouse_matches_pnp_id helper function

2014-09-13T00:30:44Z

The matches_pnp_id function from the synaptics driver is useful for other drivers too. Make it a generic psmouse helper function. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: synaptics - add support for ForcePads

2014-09-09T23:52:28Z

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of physical buttons, instead they generate primary button click when user presses somewhat hard on the surface of the touchpad. Unfortunately they also report primary button click whenever there are 2 or more contacts on the pad, messing up all multi-finger gestures (2-finger scrolling, multi-finger tapping, etc). To cope with this behavior we introduce a delay (currently 50 msecs) in reporting primary press in case more contacts appear.

Input: synaptics - use firmware data for Cr-48

2014-08-08T16:17:01Z

The profile sensor clickpad in a Cr-48 Chromebook does a reasonable job of tracking individual fingers. This tracking isn't perfect, but, experiments show that it works better than just passing "semi-mt" data to userspace, and making userspace try to deduce where the fingers are given a bounding box. This patch tries to report correct two-finger positions instead of the {(min_x, min_y), (max_x, max_y)} for profile sensor clickpads on Cr-48 chromebooks. Note that this device's firmware always reports the higher (smaller y) finger in the "sgm" packet, and the lower (larger y) finger in the "agm" packet. Thus, when a new finger arrives on the pad, the kernel driver uses input core's contact tracking facilities to match contacts with slots.

Input: synaptics - properly initialize slots for semi-MT

2014-08-08T06:37:08Z

Semi-MT devices are pointers too, so let's tell that to input_mt_init_slots(), as well as let it set up the devices as semi-MT, instead of us doing it manually. Reviewed-by: Daniel Kurtz Reviewed-by: Benson Leung Signed-off-by: Dmitry Torokhov
