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
belong to PNP bus in nature.

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.

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of
physical buttons, instead they generate primary button click when user
presses somewhat hard on the surface of the touchpad. Unfortunately they
also report primary button click whenever there are 2 or more contacts
on the pad, messing up all multi-finger gestures (2-finger scrolling,
multi-finger tapping, etc). To cope with this behavior we introduce a
delay (currently 50 msecs) in reporting primary press in case more

The profile sensor clickpad in a Cr-48 Chromebook does a reasonable job
of tracking individual fingers. This tracking isn't perfect, but,
experiments show that it works better than just passing "semi-mt" data
to userspace, and making userspace try to deduce where the fingers are
given a bounding box.
This patch tries to report correct two-finger positions instead of the
{(min_x, min_y), (max_x, max_y)} for profile sensor clickpads on Cr-48
chromebooks. Note that this device's firmware always reports the higher
(smaller y) finger in the "sgm" packet, and the lower (larger y) finger
in the "agm" packet. Thus, when a new finger arrives on the pad, the
kernel driver uses input core's contact tracking facilities to match
contacts with slots.
