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

2015-02-06T06:35:50+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

2015-01-27T16:18:57+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: i8042 - add nomux quirk for Avatar AVIU-145A6

2014-10-05T21:52:19+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: serport - add compat handling for SPIOCSTYPE ioctl

2014-10-05T21:52:19+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.

Input: serio - add firmware_id sysfs attribute

2014-06-07T17:28:19+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.
