Input: elan_i2c - add ELAN060C to the ACPI table

2017-11-15T09:09:18+00:00

commit cdea6a30c2689cc33b34c6691b57cca277f0c5dc upstream. ELAN060C touchpad uses elan_i2c as its driver. It can be found on Lenovo ideapad 320-14AST. BugLink: https://bugs.launchpad.net/bugs/1727544 Signed-off-by: Kai-Heng Feng Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: elan_i2c - add ELAN0611 to the ACPI table

2017-11-02T08:54:47+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: synaptics - fix device info appearing different on reconnect

2017-08-28T17:36:46+00:00

User-modified input settings no longer survive a suspend/resume cycle. Starting with 4.12, the touchpad is reinitialized on every reconnect because the hardware appears to be different. This can be reproduced by running the following as root: echo -n reconnect >/sys/devices/platform/i8042/serio1/drvctl A line like the following will show up in dmesg: [30378.295794] psmouse serio1: synaptics: hardware appears to be different: id(149271-149271), model(114865-114865), caps(d047b3-d047b1), ext(b40000-b40000). Note the single bit difference in caps: bit 1 (SYN_CAP_MULTIFINGER). This happens because we modify our stored copy of the device info capabilities when we enable advanced gesture mode but this change is not reflected in the actual hardware capabilities. It worked in the past because synaptics_query_hardware used to modify the stored synaptics_device_info struct instead of filling in a new one, as it does now. Fix it by no longer faking the SYN_CAP_MULTIFINGER bit when setting advanced gesture mode. This necessitated a small refactoring.

Input: ALPS - fix two-finger scroll breakage in right side on ALPS touchpad

2017-08-24T22:53:46+00:00

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 Fixes: e7348396c6d5 ("Input: ALPS - fix V8+ protocol handling (73 03 28)") Signed-off-by: Masaki Ota Tested-by: Takashi Iwai Tested-by: Paul Donohue Cc: Signed-off-by: Takashi Iwai Signed-off-by: Dmitry Torokhov

Input: trackpoint - add new trackpoint firmware ID

2017-08-19T00:04:11+00:00

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".

Similar to commit 722c5ac708b4f ("Input: elan_i2c - add ELAN0605 to the ACPI table"), ELAN0608 should be handled by elan_i2c. This touchpad can be found in Lenovo ideapad 320-14IKB.

Input: trackpoint - assume 3 buttons when buttons detection fails

2017-07-19T00:28:47+00:00

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.
