Input: i8042 - add nomux quirk for Avatar AVIU-145A6

2014-10-05T21:54:13+00:00

commit d2682118f4bb3ceb835f91c1a694407a31bb7378 upstream.

The sys_vendor / product_name are somewhat generic unfortunately, so this
may lead to some false positives. But nomux usually does no harm, where as
not having it clearly is causing problems on the Avatar AVIU-145A6.

Input: atkbd - do not try 'deactivate' keyboard on any LG laptops

2014-10-05T21:54:12+00:00

commit c01206796139e2b1feb7539bc72174fef1c6dc6e upstream.

We are getting more and more reports about LG laptops not having
functioning keyboard if we try to deactivate keyboard during probe.
Given that having keyboard deactivated is merely "nice to have"
instead of a hard requirement for probing, let's disable it on all
LG boxes instead of trying to hunt down particular models.

This change is prompted by patches trying to add "LG Electronics"/"ROCKY"
and "LG Electronics"/"LW60-F27B" to the DMI list.

Input: synaptics - add support for ForcePads

2014-10-05T21:54:12+00:00

commit 5715fc764f7753d464dbe094b5ef9cffa6e479a4 upstream.

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of
physical buttons, instead they generate primary button click when user
presses somewhat hard on the surface of the touchpad. Unfortunately they
also report primary button click whenever there are 2 or more contacts
on the pad, messing up all multi-finger gestures (2-finger scrolling,
multi-finger tapping, etc). To cope with this behavior we introduce a
delay (currently 50 msecs) in reporting primary press in case more
contacts appear.

Input: serport - add compat handling for SPIOCSTYPE ioctl

2014-10-05T21:54:12+00:00

commit a80d8b02751060a178bb1f7a6b7a93645a7a308b upstream.

When running a 32-bit inputattach utility in a 64-bit system, there will be
error code "inputattach: can't set device type". This is caused by the
serport device driver not supporting compat_ioctl, so that SPIOCSTYPE ioctl
fails.

commit 50c5d36dab930b1f1b1e3348b8608aa8b9ee7610 upstream.

We attempt to remove noise from coordinates reported by devices in
input_handle_abs_event(), unfortunately, unless we were dropping the
event altogether, we were ignoring the adjusted value and were passing
on the original value instead.

Input: elantech - don't set bit 1 of reg_10 when the no_hw_res quirk is set

2014-07-07T01:54:13+00:00

commit fb4f8f568a9def02240ef9bf7aabd246dc63a081 upstream.

The touchpad on the GIGABYTE U2442 not only stops communicating when we try
to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS
versions also when we set bit 1 (enable two finger mode auto correct).

I've asked the original reporter of:
https://bugzilla.kernel.org/show_bug.cgi?id=61151

To check that not setting bit 1 does not lead to any adverse effects on his
model / BIOS revision, and it does not, so this commit fixes the touchpad
not working on these versions by simply never setting bit 1 for laptop
models with the no_hw_res quirk.

Input: elantech - deal with clickpads reporting right button events

2014-07-07T01:54:13+00:00

commit cd9e83e2754465856097f31c7ab933ce74c473f8 upstream.

At least the Dell Vostro 5470 elantech *clickpad* reports right button
clicks when clicked in the right bottom area:

https://bugzilla.redhat.com/show_bug.cgi?id=1103528

This is different from how (elantech) clickpads normally operate, normally
no matter where the user clicks on the pad the pad always reports a left
button event, since there is only 1 hardware button beneath the path.

It looks like Dell has put 2 buttons under the pad, one under each bottom
corner, causing this.

Since this however still clearly is a real clickpad hardware-wise, we still
want to report it as such to userspace, so that things like finger movement
in the bottom area can be properly ignored as it should be on clickpads.

So deal with this weirdness by simply mapping a right click to a left click
on elantech clickpads. As an added advantage this is something which we can
simply do on all elantech clickpads, so no need to add special quirks for
this weird model.

Input: synaptics - T540p - unify with other LEN0034 models

2014-06-07T20:25:36+00:00

commit 6d396ede224dc596d92d7cab433713536e68916c upstream.

The T540p has a touchpad with pnp-id LEN0034, all the models with this
pnp-id have the same min/max values, except the T540p where the values are
slightly off. Fix them to be identical.

This is a preparation patch for simplifying the quirk table.
