Input: synaptics-rmi4 - fix error handling in I2C transport driver

2016-11-18T09:51:50+00:00

commit 261d7794c49b9a3bb5115c5ffc452e00f969bf43 upstream.

Instantiating the rmi4 I2C transport driver without interrupts assigned
(for example using manual i2c instantiation from the command line)
caused the driver to fail to load, but it does not clean up its regulator
or transport device registrations. Result is a crash at a later time,
for example when rebooting the system.

Input: i8042 - add XMG C504 to keyboard reset table

2016-11-10T15:38:53+00:00

commit da25311c7ca8b0254a686fc0d597075b9aa3b683 upstream.

The Schenker XMG C504 is a rebranded Gigabyte P35 v2 laptop.
Therefore it also needs a keyboard reset to detect the Elantech touchpad.
Otherwise the touchpad appears to be dead.

With this patch the touchpad is detected:

Input: elantech - add Fujitsu Lifebook E556 to force crc_enabled

2016-10-28T07:45:25+00:00

commit 62837b3c1a95535d1a287c9c8c6563bbd8d37033 upstream.

Another Lifebook machine that needs the same quirk as other similar
models to make the driver working.

Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries
are in alphabetical order.

Input: elantech - force needed quirks on Fujitsu H760

2016-10-28T07:45:25+00:00

commit f9a703a54d16ba2470391c4b12236ee56591d50c upstream.

Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with
the same quirks. Without this patch, the touchpad is useless out-of-the-box
as the mouse pointer won't move.

This patch makes the driver aware of both the crc_enabled=1 requirement and
the middle button, making the touchpad fully functional out-of-the-box.

Input: i8042 - skip selftest on ASUS laptops

2016-10-28T07:45:24+00:00

commit 930e19248e9b61da36c967687ca79c4d5f977919 upstream.

On suspend/resume cycle, selftest is executed to reset i8042 controller.
But when this is done in Asus devices, subsequent calls to detect/init
functions to elantech driver fails. Skipping selftest fixes this problem.

An easier step to reproduce this problem is adding i8042.reset=1 as a
kernel parameter. On Asus laptops, it'll make the system to start with the
touchpad already stuck, since psmouse_probe forcibly calls the selftest
function.

This patch was inspired by John Hiesey's change[1], but, since this problem
affects a lot of models of Asus, let's avoid running selftests on them.

All models affected by this problem:
A455LD
K401LB
K501LB
K501LX
R409L
V502LX
X302LA
X450LCP
X450LD
X455LAB
X455LDB
X455LF

Input: joydev - recognize devices with Z axis as joysticks

2016-09-27T03:03:06+00:00

Current implementation of joydev's input_device_id table recognizes only
devices with ABS_X, ABS_WHEEL or ABS_THROTTLE axes as joysticks.

There are joystick devices that do not have those axes, for example TRC
Rudder device. The device in question has ABS_Z, ABS_RX and ABS_RY axes
causing it not being detected as joystick.

This patch adds ABS_Z to the input_device_id list allowing devices with
ABS_Z axis to be detected correctly.

The silead touch-controller ICs use a different firmware per digitizer /
tablet model. So there are going to be quite a few of then and they really
should be under a separate subdir.

This commit prefixes the default firmware names with "silead/" just like
we are already doing for devicetree specified firmware names.
