The PowerA gamepad initialization quirk worked with the PowerA
wired gamepad I had around (0x24c6:0x543a), but a user reported [0]
that it didn't work for him, even though our gamepads shared the
same vendor and product IDs.
When I initially implemented the PowerA quirk, I wanted to avoid
actually triggering the rumble action during init. My tests showed
that my gamepad would work correctly even if it received a rumble
of 0 intensity, so that's what I went with.
Unfortunately, this apparently isn't true for all models (perhaps
a firmware difference?). This non-working gamepad seems to require
the real magic rumble packet that the Microsoft driver sends, which
actually vibrates the gamepad. To counteract this effect, I still
send the old zero-rumble PowerA quirk packet which cancels the
rumble effect before the motors can spin up enough to vibrate.

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.

This driver provides PS/2 serio bus support by implementing bit banging
with the GPIO API. The GPIO pins, data and clock, can be configured with
a node in the device tree or by generic device properties (GDP).
Writing to a device is supported as well, though it is possible timings
can not be halt as they are tough and difficult to reach with bit banging.
Therefore it can be configured (also in DT and GDP) whether the serio
write function should be available for clients.
This driver is for development purposes and not recommended for productive
use. However, this driver can be useful e.g. when no USB port is available
or using old peripherals is desired as PS/2 controller chips getting rare.
This driver was tested on bcm2825 and on Kirin 960 and it worked well
together with the atkbd and psmouse driver.

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 e7348396c6 ("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
