Input: synaptics - fix reporting of min coordinates

2011-07-25T08:38:21Z

We were testing wrong bit in the extended capability query. Reported-by: Daniel Kurtz Signed-off-by: Dmitry Torokhov

Input: synaptics - set minimum coordinates as reported by firmware

2011-07-09T19:33:35Z

Newer Synaptics firmware allows to query minimum coordinates reported by the device, let's use this data. Acked-by: Chase Douglas Acked-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

Input: synaptics - fuzz position for touchpad with reduced filtering

2011-07-07T06:01:09Z

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.

Input: synaptics - document 0x0c query

2011-02-23T16:53:01Z

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

Input: synaptics - add multi-finger and semi-mt support

2010-12-21T17:11:25Z

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.

Input: synaptics - fix handling of 2-button ClickPads

2010-12-01T07:59:41Z

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.

Input: synaptics - simplify pass-through port handling

2010-10-13T14:49:27Z

There was too much knowledge about internals if serio in the pass-through handling, clean it up. Signed-off-by: Dmitry Torokhov

Input: synaptics - relax capability ID checks on newer hardware

2010-07-22T01:39:03Z

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 Signed-off-by: Dmitry Torokhov

Input: synaptics - set dimensions as reported by firmware

Newer Synaptics firmware allows to query maximim dimensions reported by device, let's use this data. Tested-by: Takashi Iwai Signed-off-by: Dmitry Torokhov
