On some x86 tablets with a Goodix touchscreen, the Windows logo on the
front is a capacitive home button. Touching this button results in a touch
with bit 4 of the first byte set, while only the lower 4 bits (0-3) are
used to indicate the number of touches.
Report a KEY_LEFTMETA press when this happens.
Note that the hardware might support more than one button, in which
case the "id" byte of coor_data would identify the button in question.
This is not implemented as we don't have access to hardware with
multiple buttons.

Here is the "big" driver core update for 4.14-rc1.
It's really not all that big, the largest thing here being some firmware
tests to help ensure that that crazy api is working properly.
There's also a new uevent for when a driver is bound or unbound from a
device, fixing a hole in the driver model that's been there since the
very beginning. Many thanks to Dmitry for being persistent and pointing
out how wrong I was about this all along :)
Patches for the new uevents are already in the systemd tree, if people
want to play around with them.
Otherwise just a number of other small api changes and updates here,
nothing major. All of these patches have been in linux-next for a

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

To prepare an upcoming patch adding support for another PMIC that has
different startup and shutdown time, use driver_data of
platform_device_id instead of a fixed extended device attribute.
By doing so, we also remove a lot of nested structures that aren't
useful.
With this patch, a new PMIC can be easily supported by just filling
correctly its ax20x_info structure and adding a platform_device_id.
Moreover, since we get rid of extended attributes, rename
axp20x_store_ext_attr to axp20x_store_attr and axp20x_show_ext_attr to
axp20x_show_attr.
