Pull documentation update from Jonathan Corbet:
 "Here's my set of accumulated documentation changes for 3.19.

  It includes a couple of additions to the coding style document, some
  fixes for minor build problems within the documentation tree, the
  relocation of the kselftest docs, and various tweaks and additions.

  A couple of changes reach outside of Documentation/; they only make
  trivial comment changes and I did my best to get the required acks.

5469b19650 Input: xpad - update docs to reflect current state
The last time this documentation was accurate was
just over 8 years ago. In this time we've added
support for two new generations of Xbox console
controllers and dozens of third-party controllers.

This patch unifies terminology and makes it explicit
which model of controller a sentence refers to.

It also expands certain sections to address the latest
versions of Xbox controllers.

Thus this documentation should now be useful to
end users and not contain out-right untruths.

This is the patch's second revision. Prior versions
of this patch altered the driver's TODO list. That
change has been pulled out of this documentation
update patch.

36189cc3cd Input: elantech - fix touchpad initialization on Gigabyte U2442
The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the
driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"

Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

It wasn't really clear from the gamepad-API description how ABS values are
mapped exactly. Clarify that negative is left/up and positive is
right/down. Unfortunately, this means I screwed up the Wii U ProController
ABI. Anyhow, this just means we continue to have 0 compatible gamepad
drivers in the kernel. User-space needs to fix them up, anyway, as all
other gamepads are also incompatible.

6e0fe2e572 input: document gamepad API and add extra keycodes
Until today all gamepad input drivers report their data differently. It is
nearly impossible to write applications for more than one device in a
generic way. Therefore, this patch introduces a uniform gamepad API which
will be used for all new drivers.

Instead of mapping buttons by their labels, we now map them by position.
This allows applications to work with any gamepad regardless of the labels
on the buttons. Furthermore, we standardize the ABS_* codes for analog
triggers and sticks.

For D-Pads the long overdue BTN_DPAD_* codes are introduced. They should
be fairly obvious how to use. To avoid confusion, the action buttons now
have BTN_EAST/SOUTH/WEST/NORTH aliases.

257867dc8d Input: MT - Specify that ABS_MT_SLOT must have a minimum of 0
This is effectively already in force through input_mt_init_slots, and uinput
too ignores the actual minimum.

Since slots are a kernel-genenerated axis only, non-zero minimums make
little sense and are likely to cause errors. Better to treat a non-zero
minimum as kernel bug if it ever happens.

3bfd5c5baf Input: add generic GPIO-tilt driver
There exist tilt switches that simply report their tilt-state via
some gpios. The number and orientation of their axes can vary
depending on the switch used and the build of the device. Also two
or more one-axis switches could be combined to provide multi-dimensional
orientation.

One example of a device using such a switch is the family of Qisda
ebook readers, where the switch provides information about the
landscape / portrait orientation of the device. The example in
Documentation/input/gpio-tilt.txt documents exactly this one-axis
device.

395cf9691d doc: fix broken references
There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.

Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

1dc6edec12 Input: elantech - add v4 hardware support
v4 hardware is a true multitouch capable touchpad (up to 5 fingers).
The packet format is quite complex, please see protocol document for
reference.

v3 hardware's packet format is almost identical to v2 (one/three finger touch),
except when sensing two finger touch, the hardware sends 12 bytes of data.

a93bd154d8 Input: mt - document devices reporting more touches than slots
Some devices are capable of identifying and/or tracking more contacts than
they can report to the driver.  Document how a driver should handle this,
and what userspace should expect.

Éric Piel
71c6d18859 Input: elantech - describe further the protocol
For some Dell laptops, Ubuntu had a special version of the elantech
driver with more knowledge on the devices. It can be found there:
http://zinc.ubuntu.com/git?p=mid-team/hardy-netbook.git;a=blob;f=drivers/input/mouse/elantech.c;h=d0e2cafed162428f72e3654f4dda85e08ea486b3;hb=refs/heads/abi-22

By inspecting the source code, and doing some test on a real hardware, I
have completed the protocol specification (especially for the 6 bytes
protocol). It also adds information about the mapping between the
version reported by the device and the protocol to use.

9fb0f14e31 Input: evdev - indicate buffer overrun with SYN_DROPPED
Add a new EV_SYN code, SYN_DROPPED, to inform the client when input
events have been dropped from the evdev input buffer due to a
buffer overrun.  The client should use this event as a hint to
reset its state or ignore all following events until the next
packet begins.
