Input: i8042 - lower log level for "no controller" message

2016-05-11T13:03:12+00:00

commit f5d75341fac6033f6afac900da110cc78e06d40d upstream.

Nowadays the machines without i8042 controller is popular, and no need
to print "No controller found" message in the error log level, which
annoys at booting in quiet mode.  Let's lower it info level.

Input: i8042 - add Fujitsu Lifebook U745 to the nomux list

2016-02-25T09:49:11+00:00

commit dd0d0d4de582a6a61c032332c91f4f4cb2bab569 upstream.

Without i8042.nomux=1 the Elantech touch pad is not working at all on
a Fujitsu Lifebook U745. This patch does not seem necessary for all
U745 (maybe because of different BIOS versions?). However, it was
verified that the patch does not break those (see opensuse bug 883192:
https://bugzilla.opensuse.org/show_bug.cgi?id=883192).

Input: serio - fix blocking of parport

2015-10-28T15:38:30+00:00

commit 1a5e251996e1b602f2ddc9261ee9de0ca1875bfa upstream.

If parkbd_allocate_serio() fails to allocate memory we are releasing the
parport but we missed unregistering the device. As a result this device
with exclusive access to that parport remains registered. And no other
device will be able to use that parport even though this driver has
failed to load.

Input: i8042 - add noloop quirk for Medion Akoya E7225 (MD98857)

2015-02-08T19:01:58+00:00

commit 1d90d6d5522befa8efa1a7ea406be65cf865ded4 upstream.

Without this the aux port does not get detected, and consequently the touchpad
will not work.

With this patch the touchpad is detected:

Input: i8042 - reset keyboard to fix Elantech touchpad detection

2015-01-29T14:44:42+00:00

commit 148e9a711e034e06310a8c36b64957934ebe30f2 upstream.

On some laptops, keyboard needs to be reset in order to successfully detect
touchpad (e.g., some Gigabyte laptop models with Elantech touchpads).
Without resettin keyboard touchpad pretends to be completely dead.

Based on the original patch by Mateusz Jończyk this version has been
expanded to include DMI based detection & application of the fix
automatically on the affected models of laptops. This has been confirmed to
fix problem by three users already on three different models of laptops.

Input: serio - add firmware_id sysfs attribute

2014-12-06T13:48:31+00:00

commit 0456c66f4e905e1ca839318219c770988b47975c upstream.

serio devices exposed via platform firmware interfaces such as ACPI may
provide additional identifying information of use to userspace.

We don't associate the serio devices with the firmware device (we don't
set it as parent), so there's no way for userspace to make use of this
information.

We cannot change the parent for serio devices instantiated though a
firmware interface as that would break suspend / resume ordering.

Therefore this patch adds a new firmware_id sysfs attribute so that
userspace can get a string from there with any additional identifying
information the firmware interface may provide.

Input: altera_ps2 - write to correct register when disabling interrupts

2014-11-19T22:15:22+00:00

commit d0269b8475020718afd7f559064698f5500fa879 upstream.

In altera_ps2_close, the data register (offset 0) is written instead of
the control register (offset 4), leading to the RX interrupt not being
disabled. Fix this by calling writel() with the offset for the proper
register.

commit 993b3a3f80a7842a48cd46c2b41e1b3ef6302468 upstream.

These models need i8042.notimeout, otherwise the touchpad will not work.
