Input: elan_i2c - extend Flash-Write delay

2017-09-22T17:07:38+00:00

The original 20ms delay is only marginally enough delay after a block write
operation during firmware update. Let's increase the delay to ensure that
the controller finishes up storing the page to avoid failures in the
firmware updates.

Input: elantech - make arrays debounce_packet static, reduces object code size

2017-09-11T21:23:40+00:00

Don't populate the arrays debounce_packet on the stack, instead make
them static.  Makes the object code smaller by over 870 bytes:

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

Input: elan_i2c - support touchpads with two physical buttons

2017-08-19T00:07:02+00:00

Elan touchpads on Asus ROG G752xx series laptops have 2 physical buttons.
Luckily we can query the touchpad to see if it is a clickpad variant and
adjust the behavior accordingly.

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".
