Input: elan_i2c - add ELAN0611 to the ACPI table

2017-11-02T08:49:14+00:00

commit 57a95b41869b8f0d1949c24df2a9dac1ca7082ee upstream.

ELAN0611 touchpad uses elan_i2c as its driver. It can be found
on Lenovo ideapad 320-15IKB.

So add it to ACPI table to enable the touchpad.

[Ido Adiv  reports that the same ACPI ID is used for
Elan touchpad in ideapad 520].

Input: trackpoint - assume 3 buttons when buttons detection fails

2017-09-09T15:39:39+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: ALPS - fix two-finger scroll breakage in right side on ALPS touchpad

2017-08-30T08:21:44+00:00

commit 4a646580f793d19717f7e034c8d473b509c27d49 upstream.

Fixed the issue that two finger scroll does not work correctly
on V8 protocol. The cause is that V8 protocol X-coordinate decode
is wrong at SS4 PLUS device. I added SS4 PLUS X decode definition.

Mote notes:
the problem manifests itself by the commit e7348396c6d5 ("Input: ALPS
- fix V8+ protocol handling (73 03 28)"), where a fix for the V8+
protocol was applied.  Although the culprit must have been present
beforehand, the two-finger scroll worked casually even with the
wrongly reported values by some reason.  It got broken by the commit
above just because it changed x_max value, and this made libinput
correctly figuring the MT events.  Since the X coord is reported as
falsely doubled, the events on the right-half side go outside the
boundary, thus they are no longer handled.  This resulted as a broken
two-finger scroll.

One finger event is decoded differently, and it didn't suffer from
this problem.  The problem was only about MT events. --tiwai

Input: trackpoint - add new trackpoint firmware ID

2017-08-30T08:21:44+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: elan_i2c - add ASUS EeeBook X205TA special touchpad fw

2017-03-30T07:41:22+00:00

commit 92ef6f97a66e580189a41a132d0f8a9f78d6ddce upstream.

EeeBook X205TA is yet another ASUS device with a special touchpad
firmware that needs to be accounted for during initialization, or
else the touchpad will go into an invalid state upon suspend/resume.
Adding the appropriate ic_type and product_id check fixes the problem.
