Input: synaptics - set minimum coordinates as reported by firmware

2011-07-09T19:33:35+00:00

Newer Synaptics firmware allows to query minimum coordinates reported by
the device, let's use this data.

Input: synaptics - process button bits in AGM packets

2011-07-07T06:01:17+00:00

AGM packets contain valid button bits, too.
This patch refactors packet processing to parse button bits in AGM packets.
However, they aren't actually used or reported.

The point is to more completely process AGM packets,
and prepare for future patches that may actually use AGM packet button bits.

Input: synaptics - fuzz position for touchpad with reduced filtering

2011-07-07T06:01:09+00:00

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 - set resolution for MT_POSITION_X/Y axes

2011-07-07T06:01:00+00:00

Set resolution for MT_POSITION_X and MT_POSITION_Y to match ABS_X and
ABS_Y, respectively.

Input: synaptics - fix crash in synaptics_module_init()

2011-03-31T07:04:52+00:00

'struct dmi_system_id' arrays must always have a terminator to keep
dmi_check_system() from looking at data (and possibly crashing) it
isn't supposed to look at.

The issue went unnoticed until ef8313bb1a22e7d2125d9d758aa8a81f1de91d81,
but was introduced about a year earlier with
7705d548cbe33f18ea7713b9a07aa11047aaeca4 (which also similarly changed
lifebook.c, but the problem there got eliminated shortly afterwards).

The first hunk therefore is a stable candidate back to 2.6.33, while
the full change is needed only on 2.6.38.

Input: synaptics - retry failed resets when reconnecting

2011-01-29T06:32:07+00:00

On some machines, like Dell Studio XPS 16 (1640), touchpad fails to
respond to the standard query after first reset but may start
responding later, so let's repeat reset sequence several (3) times.

Input: synaptics - fix reconnect logic on MT devices

2011-01-29T06:32:03+00:00

synaptics_set_advanced_gesture_mode() affect capabilities bits we should
perform comparison after calling this function, otherwise they will never
match and we will be forced to perform full reconnect.

Input: psmouse - disable the synaptics extension on OLPC machines

2010-12-23T09:21:23+00:00

OLPC has switched to a Synaptics touchpad.  It turns out that it's
pretty useless in absolute mode.  This patch looks for an OLPC
system (via DMI tables), and refuses to init Synaptics mode in
that scenario (falling back to relative mode).
