Input: i8042 - allow KBD and AUX ports to wake up from suspend-to-idle

2015-03-10T00:05:31+00:00

While registering serio device for i8042, mark them as wakeup-capable
and check their user space wakeup settings in i8042_pm_suspend() and
i8042_pm_resume() to enable or disable, respectively, their interrupts
to wake up the system.

This makes it possible to use the PC keyboard to wake up the system
from suspend-to-idle, among other things, after writing "enabled" to
the keyboard serio device's power/wakeup sysfs attribute.

Input: i8042 - reset keyboard to fix Elantech touchpad detection

2015-01-08T01:20:44+00:00

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.

Remove all .owner fields from platform drivers

Revert "Input: i8042 - disable active multiplexing by default"

2014-10-31T16:35:53+00:00

This reverts commit 68da166491655bc54051bf04c78ce648e2e33508.

It turns out that the assertion about scope of regressions due to
always keeping keyboard controller in legacy mode was proven wrong.
There are laptops, such as Clevo W650SH, that only have internal
touchpad (no external PS/2 ports), that require active multiplexing
mode to switch the touchpad (Elantech) into native mode instead of
basic PS/2 emulation.

input: serio: drop owner assignment from platform_drivers

2014-10-20T14:20:41+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

Input: i8042 - disable active multiplexing by default

2014-10-11T18:34:43+00:00

Active multiplexing is a nice feature as it allows several pointing devices
(such as touchpad and external mouse) use their native protocols at the
same time. Unfortunately many manufacturers do not implement the feature
properly even though they advertise it. The problematic implementations are
never fixed, since Windows by default does not use this mode, and move from
one BIOS/model of laptop to another. When active multiplexing is broken
turning it on usually results in touchpad, keyboard, or both unresponsive.

With PS/2 usage on decline (most of PS/2 devices in use nowadays are
internal laptop touchpads), I expect number of users who have laptops with
working MUX implementation, docking stations with external PS/2 ports, and
who are still using external PS/2 mice, to be rather small. Let's flip the
default to be OFF and allow activating it through i8042.nomux=0 kernel
option.  We'll also keep DMI table where we can record known good models.
