Revert "Input: synaptics - fix handling of disabling gesture mode"

2015-10-02T17:31:32+00:00

This reverts commit e51e38494a8ecc18650efb0c840600637891de2c: we
actually do want the device to work in extended W mode, as this is the
mode that allows us receiving multiple contact information.

Input: synaptics - fix handling of disabling gesture mode

2015-08-26T17:09:22+00:00

Bit 2 of the mode byte has dual meaning: it can disable reporting of
gestures when touchpad works in Relative mode or normal Absolute mode,
or it can enable so called Extended W-Mode when touchpad uses enhanced
Absolute mode (W-mode). The extended W-Mode confuses our driver and
causes missing button presses on some Thinkpads (x250, T450s), so let's
make sure we do not enable it.

Also, according to the spec W mode "... bit is defined only in Absolute
mode on pads whose capExtended capability bit is set. In Relative mode and
in TouchPads without this capability, the bit is reserved and should be
left at 0.", so let's make sure we respect this requirement as well.

Make extended capabilities obtained through $10 query also available in
touchpad identification.

This reverts commit 63c4fda3c0bb841b1aad1298fc7fe94058fc79f8 as it

Input: synaptics - allocate 3 slots to keep stability in image sensors

2015-04-06T16:38:07+00:00

When slowly dropping 1, 2 and then 3 fingers on an image sensor touchpad,
we can see that the first finger gets reassigned a new slot while it did
not move. This is due to the kernel tracking algorithm which can not assign
correctly the 3 touches, being out of slots.

Declaring that we support 3 slots allows to actually forward:
slot 0 -> down, slot 1 -> up, slot 2 -> down

This reverts commit 09d042a2eb90 ("Revert "Input: synaptics - use dmax in
input_mt_assign_slots"")

Now that balanced slots assignments seem to be fixed, let's re-enable the
use in synaptics.c and wait for users to complain if there are still
problems.

Input: synaptics - add quirk for Thinkpad E440

2015-03-23T17:35:42+00:00

Its ClickPad shares PNP ID "LEN2006" with the one in model E540 which is
already handled by the driver (both are Haswell iterations of the Edge
line, launched in 2014) but the dimensions it reports are different:

  $ sudo ./touchpad-edge-detector /dev/input/event3
  Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event3
  Move one finger around the touchpad to detect the actual edges
  Kernel says: x [1472..5044], y [1408..3398]
  Touchpad sends: x [1024..5045], y [2457..4832] /^C

Fortunately we can use the board ID, which is also different, to
distinguish among them.
