84a90b610a Input: elantech - better support all those v2 variants
V2 hardware has many variants. This patch adddresses two issues:

 - some model also has debounce packets, but with a different signature
   than v3. Now we just check debounce for all v2 hardware.

 - due to different scanning methods the hardware uses, x and y ranges have
   to be calculated differently. And for some specific versions, we can just
   see them as custom-made, so set {x, y} the same values as Windows driver
   does.

6b4b49fea1 Input: synaptics - process finger (<=5) transitions
Synaptics image sensor touchpads track up to 5 fingers, but only report 2.
They use a special "TYPE=2" (AGM-CONTACT) packet type that reports
the number of tracked fingers and which finger is reported in the SGM
and AGM packets.

With this new packet type, it is possible to tell userspace when 4 or 5
fingers are touching.

4dc772d274 Input: synaptics - process finger (<=3) transitions
Synaptics image sensor touchpads track 5 fingers, but only report 2.
This patch attempts to deal with some idiosyncrasies of these touchpads:

 * When there are 3 or more fingers, only two are reported.
 * The touchpad tracks the 5 fingers in slot[0] through slot[4].
 * It always reports the lowest and highest valid slots in SGM and AGM
   packets, respectively.
 * The number of fingers is only reported in the SGM packet.  However,
   the number of fingers can change either before or after an AGM
   packet.
 * Thus, if an SGM reports a different number of fingers than the last
   SGM, it is impossible to tell whether the intervening AGM corresponds
   to the old number of fingers or the new number of fingers.
 * For example, when going from 2->3 fingers, it is not possible to tell
   whether tell AGM contains slot[1] (old 2nd finger) or slot[2] (new
   3rd finger).
 * When fingers are added one at at time, from 1->2->3, it is possible to
   track which slots are contained in the SGM and AGM packets:
     1 finger:  SGM = slot[0], no AGM
     2 fingers: SGM = slot[0], AGM = slot[1]
     3 fingers: SGM = slot[0], AGM = slot[2]
 * It is also possible to track which slot is contained in the SGM when 1
   of 2 fingers is removed.  This is because the touchpad sends a special
   (0,0,0) AGM packet whenever all fingers are removed except slot[0]:
     Last AGM == (0,0,0): SGM contains slot[1]
     Else: SGM contains slot[0]
 * However, once there are 3 fingers, if exactly 1 finger is removed, it
   is impossible to tell which 2 slots are contained in SGM and AGM.
   The (SGM,AGM) could be (0,1), (0,2), or (1,2). There is no way to know.
 * Similarly, if two fingers are simultaneously removed (3->1), then it
   is only possible to know if SGM still contains slot[0].
 * Since it is not possible to reliably track which slot is being
   reported, we invalidate the tracking_id every time the number of
   fingers changes until this ambiguity is resolved when:
     a) All fingers are removed.
     b) 4 or 5 fingers are touched, generates an AGM-CONTACT packet.
     c) All fingers are removed except slot[0].  In this special case, the
        ambiguity is resolved since by the (0,0,0) AGM packet.

Behavior of the driver:

When 2 or more fingers are present on the touchpad, the kernel reports
up to two MT-B slots containing the position data for two of the fingers
reported by the touchpad.  If the identity of a finger cannot be tracked
when the number-of-fingers changes, the corresponding MT-B slot will be
invalidated (track_id set to -1), and a new track_id will be assigned in
a subsequent input event report.

The driver always reports the total number of fingers using one of the
EV_KEY/BTN_TOOL_*TAP events. This could differ from the number of valid
MT-B slots for two reasons:
 a) There are more than 2 fingers on the pad.
 b) During ambiguous number-of-fingers transitions, the correct track_id
    for one or both of the slots cannot be determined, so the slots are
    invalidated.

Thus, this is a hybrid singletouch/MT-B scheme. Userspace can detect
this behavior by noting that the driver supports more EV_KEY/BTN_TOOL_*TAP
events than its maximum EV_ABS/ABS_MT_SLOT.

a6ca40c11e Input: synaptics - decode AGM packet types
A Synaptics image sensor tracks 5 fingers, but can only report 2.

The algorithm for choosing which 2 fingers to report and in which packet:
  Touchpad maintains 5 slots, numbered 0 to 4
  Initially all slots are empty
  As new fingers are detected, assign them to the lowest available slots
  The touchpad always reports:
    SGM: lowest numbered non-empty slot
    AGM: highest numbered non-empty slot, if there is one

In addition, these touchpads have a special AGM packet type which reports
the number of fingers currently being tracked, and which finger is in
each of the two slots.  Unfortunately, these "TYPE=2" packets are only used
when more than 3 fingers are being tracked.  When less than 4 fingers
are present, the 'w' value must be used to track how many fingers are
present, and knowing which fingers are being reported is much more
difficult, if not impossible.

3cdfee9ea7 Input: synaptics - add image sensor support
Synaptics makes (at least) two kinds of touchpad sensors:
 * Older pads use a profile sensor that could only infer the location
   of individual fingers based on the projection of their profiles
   onto row and column sensors.
 * Newer pads use an image sensor that can track true finger position
   using a two-dimensional sensor grid.

Both sensor types support an "Advanced Gesture Mode":
 When multiple fingers are detected, the touchpad sends alternating
 "Advanced Gesture Mode" (AGM) and "Simple Gesture Mode" (SGM)
 packets.
 The AGM packets have w=2, and contain reduced resolution finger data
 The SGM packets have w={0,1} and contain full resolution finger data

Profile sensors try to report the "upper" (larger y value) finger in
the SGM packet, and the lower (smaller y value) in the AGM packet.
However, due to the nature of the profile sensor, they easily get
confused when fingers cross, and can start reporting the x-coordinate
of one with the y-coordinate of the other.  Thus, for profile
sensors, "semi-mt" was created, which reports a "bounding box"
created by pairing min and max coordinates of the two pairs of
reported fingers.

Image sensors can report the actual coordinates of two of the fingers
present.  This patch detects if the touchpad is an image sensor and
reports finger data using the MT-B protocol.

NOTE: This patch only adds partial support for 2-finger gestures.
      The proper interpretation of the slot contents when more than
      two fingers are present is left to later patches.  Also,
      handling of 'number of fingers' transitions is incomplete.

7afdb842d9 Input: synaptics - refactor agm packet parsing
When a Synaptics touchpad is in "AGM" mode, and multiple fingers are
detected, the touchpad sends alternating "Advanced Gesture Mode" (AGM) and

  The AGM packets have w=2, and contain reduced resolution finger data.
  The SGM packets have w={0,1} and contain full resolution finger data.

Refactor the parsing of agm packets to its own function, and rename the
synaptics_data.mt field to .agm to indicate that it contains the contents of
the last agm packet.

7786908c3c input/atari: Use the correct mouse interrupt hook
The Atari keyboard driver calls atari_mouse_interrupt_hook if it's set, not
atari_input_mouse_interrupt_hook. Fix below.

[geert] Killed off atari_mouse_interrupt_hook completely, after fixing another
incorrect assignment in atarimouse.c.

9cb6cfae4e Input: elantech - remove support for proprietary X driver
Apparently somewhere someone had a proprietary X driver. To get the
multitouch info, it uses some hack on the normal API instead of using
the multitouch protocol. Now that the multitouch info is transmitted
correctly it makes not much sense to keep it. Especially because it's
impossible to find this proprietary X driver anywhere, so the number of
users must be very low.

89eec4d71e Input: elantech - report multitouch with proper ABS_MT messages
Multitouch info was reported only via a old protocol used by the
proprietary X driver from elantech. Let's report the multitouch info
also following the official MT protocol. It's semi-mt because the device
only reports the lowest/highest coordinates.

This was done following the multi-touch-protocol.txt documentation, and
inspired by the bcm5974 and elantech implementations. Testing was light
as there is not many applications using this protocol yet, but the X
synaptics driver didn't complain and the X multitouch driver behaved
correctly.

708748670c Input: synaptics - fix crash in synaptics_module_init()
'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 ef8313bb1a,
but was introduced about a year earlier with
7705d548cb (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.
