Input: trackpoint - assume 3 buttons when buttons detection fails

2017-09-13T21:03:46+00:00

commit 293b915fd9bebf33cdc906516fb28d54649a25ac upstream.

Trackpoint buttons detection fails on ThinkPad 570 and 470 series,
this makes the middle button of the trackpoint to not being recogized.
As I don't believe there is any trackpoint with less than 3 buttons this
patch just assumes three buttons when the extended button information
read fails.

Input: trackpoint - add new trackpoint firmware ID

2017-08-30T08:16:55+00:00

commit ec667683c532c93fb41e100e5d61a518971060e2 upstream.

Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits
are indicated as TP. Change the constant to bitwise values.

This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead
of it being identified as "PS/2 Generic Mouse".

Input: elantech - add Fujitsu Lifebook E547 to force crc_enabled

2017-04-30T03:49:13+00:00

commit 704de489e0e3640a2ee2d0daf173e9f7375582ba upstream.

Temporary got a Lifebook E547 into my hands and noticed the touchpad
only works after running:

	echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled

Add it to the list of machines that need this workaround.

Input: elantech - add more IC body types to the list

[ Upstream commit 226ba707744a51acb4244724e09caacb1d96aed9 ]

The touchpad in HP Pavilion 14-ab057ca reports it's version as 12 and
according to Elan both 11 and 12 are valid IC types and should be
identified as hw_version 4.

Input: synaptics - handle spurious release of trackstick buttons, again

Looks like the fimware 8.2 still has the extra buttons spurious release
bug.

Input: elantech - mark protocols v2 and v3 as semi-mt

2016-02-10T03:56:36+00:00

[ Upstream commit 6544a1df11c48c8413071aac3316792e4678fbfb ]

When using a protocol v2 or v3 hardware, elantech uses the function
elantech_report_semi_mt_data() to report data. This devices are rather
creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid
touch is reported.

Anyway, userspace (libinput) is now confused by these (0,0) touches,
and detect them as palm, and rejects them.

Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW")
was sufficient enough for xf86-input-synaptics and libinput before it has
palm rejection. Now we need to actually tell libinput that this device is
a semi-mt one and it should not rely on the actual values of the 2 touches.

Input: psmouse - add small delay for IBM trackpoint pass-through mode

2015-12-03T04:25:32+00:00

[ Upstream commit 66bc2f51ef7deabc8b8f3baa98ae64b65e5e973a ]

There are trackpoint devices that fail to respond to the PS2 command
PSMOUSE_CMD_GETID if immediately queried after the parent device is
deactivated. Add a small delay for the hardware to get in a sane state
before sending any PS2 commands.

One example of such a system is:
Lenovo ThinkPad X120e, model 30515QG

This reverts commit e73268af3e137b1f69d0f82d80aa88e0e8c7cbbe.

Seems like an incorrect merge on my end, will pick the upstream
version again next.
