The error message "Can't read CTR while initializing i8042" appears on
Cherry Trail-based devices at each boot time:
i8042: PNP: No PS/2 controller found. Probing ports directly.
i8042: Can't read CTR while initializing i8042
i8042: probe of i8042 failed with error -5
This happens because we historically do not trust firmware on X86 and,
while noting that PNP does not show keyboard or mouse devices, we still
charge ahead and try to probe the controller. Let's relax this a bit and if
results of PNP probe agree with the results of platform
initialization/quirks conclude that there is, in fact, no i8042.
While at it, let's avoid using x86_platform.i8042_detect() and instead
abort execution early if platform indicates that it can not possibly have
i8042 (x86_platform.legacy.i8042 equals X86_LEGACY_I8042_PLATFORM_ABSENT).

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:

Merge tag 'v4.8' into next
Sync up with mainline to bring in I2C host notify changes and other
updates.
On suspend/resume cycle, selftest is executed to reset i8042 controller.
But when this is done in Asus devices, subsequent calls to detect/init
functions to elantech driver fails. Skipping selftest fixes this problem.
An easier step to reproduce this problem is adding i8042.reset=1 as a
kernel parameter. On Asus laptops, it'll make the system to start with the
touchpad already stuck, since psmouse_probe forcibly calls the selftest
function.
This patch was inspired by John Hiesey's change[1], but, since this problem
affects a lot of models of Asus, let's avoid running selftests on them.

The Pulse-Eight USB CEC adapter is a usb device that shows up as a ttyACM0
device. It requires that you run inputattach in order to communicate with
it via serio.
This all works well, but it would be nice to have a udev rule to
automatically start inputattach. That too works OK, but the problem comes
when the USB device is unplugged: the tty hangup is never handled by the
serio framework so the inputattach utility never exits and you have to kill
it manually.
By adding this hangup callback the inputattach utility now properly exits
as soon as the USB device is unplugged.
The udev rule I used on my Debian sid system is:
SUBSYSTEM=="tty", KERNEL=="ttyACM[0-9]*", ATTRS{idVendor}=="2548", ATTRS{idProduct}=="1002", ACTION=="add", TAG+="systemd", ENV{SYSTEMD_WANTS}+="pulse8-cec-inputattach@%k.service"
And /etc/systemd/system/pulse8-cec-inputattach@.service is as follows:
===============================================================
[Unit]
Description=inputattach for pulse8-cec device on %I

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.

- DD core can report the same if required
- since commit 013c074f86 ("PM / sleep: prohibit devices probing

System suspend and deferred device will be carefully reprobed once
Resume is finished.

Debugging input devices, specifically laptop touchpads, can be tricky
without having the physical device handy. Here we try to remedy that
with userio. This module allows an application to connect to a character
device provided by the kernel, and emulate any serio device. In
combination with userspace programs that can record PS/2 devices and
replay them through the /dev/userio device, this allows developers to
debug driver issues on the PS/2 level with devices simply by requesting
a recording from the user experiencing the issue without having to have
the physical hardware in front of them.

If the upcoming system suspend is not going to be handled by the
platform firmware, like in the suspend-to-idle case, it is not
necessary to reset the controller in i8042_pm_suspend(), so avoid
doing that.
Moreover, if the system resume currently in progress has not been
started by the platform firmware, like in the suspend-to-idle case,
i8042_controller_resume() need not be called by i8042_pm_resume(),
so avoid doing that too in that case.
Additionally, try to catch the event that woke up the system by

__ps2_command reads that data concurrently with the interrupt handler. As
the result, for example, if a response arrives just after the timeout,
__ps2_command can copy out garbage from ps2dev->cmdbuf but then see that
ps2dev->cmdcnt is 0 and return success.
Stop the interrupt handler with serio_pause_rx() before reading the

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.

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.

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