Input: i8042 - add Clevo P650RS to the i8042 reset list

2017-05-17T19:08:24+00:00

[ Upstream commit 7c5bb4ac2b76d2a09256aec8a7d584bf3e2b0466 ]

Clevo P650RS and other similar devices require i8042 to be reset in order
to detect Synaptics touchpad.

Input: i8042 - add noloop quirk for Dell Embedded Box PC 3000

2017-05-17T19:07:00+00:00

[ Upstream commit 45838660e34d90db8d4f7cbc8fd66e8aff79f4fe ]

The aux port does not get detected without noloop quirk, so external PS/2
mouse cannot work as result.

The PS/2 mouse can work with this quirk.

Input: i8042 - add XMG C504 to keyboard reset table

2016-11-26T03:57:01+00:00

[ Upstream commit da25311c7ca8b0254a686fc0d597075b9aa3b683 ]

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: i8042 - set up shared ps2_cmd_mutex for AUX ports

2016-08-31T23:21:09+00:00

[ Upstream commit 47af45d684b5f3ae000ad448db02ce4f13f73273 ]

The commit 4097461897df ("Input: i8042 - break load dependency ...")
correctly set up ps2_cmd_mutex pointer for the KBD port but forgot to do
the same for AUX port(s), which results in communication on KBD and AUX
ports to clash with each other.

Input: i8042 - break load dependency between atkbd/psmouse and i8042

2016-08-20T03:07:58+00:00

[ Upstream commit 4097461897df91041382ff6fcd2bfa7ee6b2448c ]

As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we
have a hard load dependency between i8042 and atkbd which prevents
keyboard from working on Gen2 Hyper-V VMs.

> hyperv_keyboard invokes serio_interrupt(), which needs a valid serio
> driver like atkbd.c.  atkbd.c depends on libps2.c because it invokes
> ps2_command().  libps2.c depends on i8042.c because it invokes
> i8042_check_port_owner().  As a result, hyperv_keyboard actually
> depends on i8042.c.
>
> For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a
> Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m
> rather than =y, atkbd.ko can't load because i8042.ko can't load(due to
> no i8042 device emulated) and finally hyperv_keyboard can't work and
> the user can't input: https://bugs.archlinux.org/task/39820
> (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y)

To break the dependency we move away from using i8042_check_port_owner()
and instead allow serio port owner specify a mutex that clients should use
to serialize PS/2 command stream.

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

2016-02-01T19:54:05+00:00

[ Upstream commit dd0d0d4de582a6a61c032332c91f4f4cb2bab569 ]

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: 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: gscps2 - fix MODULE_DEVICE_TABLE invocation

2015-02-04T19:35:54+00:00

The patch "module: fix types of device tables aliases" newly requires
that invocations of

MODULE_DEVICE_TABLE(type, name);

come *after* the definition of `name'.  That is reasonable, but gscps2
wasn't doing this.  Fix it.
