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.

ACPI device enumeration mechanism changed a lot since 3.16-rc1.
ACPI device objects with _HID will be enumerated to platform bus by default.
For the existing PNP drivers that probe the PNPACPI devices, the device ids
are listed explicitly in drivers/acpi/acpi_pnp.c.
But ACPI folks will continue their effort on shrinking this id list by
converting the PNP drivers to platform drivers, for the devices that don't

The Asus X450 and X550 laptops use a PS/2 touchpad from a new
manufacturer called FocalTech:
https://bugzilla.kernel.org/show_bug.cgi?id=77391https://bugzilla.redhat.com/show_bug.cgi?id=1110011
The protocol for these devices is not known at this time, but even
without knowing the protocol they need some special handling. They get
upset by some of our other PS/2 device probing, and once upset generate
random mouse events making things unusable even with an external mouse.
This patch adds detection of these devices based on their pnp ids, and
when they are detected, treats them as a bare ps/2 mouse. Doing things
this way they at least work in their ps/2 mouse emulation mode.

The current codes in gameport and analog joystick drivers for the time
accounting have a long-standing problem when the system is running
with CPU freq; since the timing is measured via TSC or sample counter,
the calculation isn't reliable.
In this patch, as a simple fix, use the standard ktime to measure the
timing. In case where no high resolution timer is available,
use_ktime bool option is provided to both modules. Setting
use_ktime=false switches to the old methods.

Many palmas family of PMICs have support for interrupt based power button.
This allows the device to notify the processor of external push button
events over the shared palmas interrupt. However, this event is generated
only during a "press" operation. Software is supposed to poll(sigh!) for
detecting a release event.
The PMIC also supports ability to power off independent of the software
decisions when the button is pressed for a long duration if the PMIC is
appropriately configured on the platform.
Even though the function is similar to twl4030_pwrbutton, it is
substantially different in operation to belong to a new driver of it's own.
