Stephen Chandler Paul 5523662edd Input: add userio module
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.

Ezequiel Garcia 3a341a4c30 Input: rotary-encoder - add support for quarter-period mode
Some encoders have both outputs low in stable states, others also have
a stable state with both outputs high (half-period mode) and some have
a stable state in all steps (quarter-period mode). The driver used to
support the former states and with this change it can also support the
later.

This commit also deprecates the 'half-period' property and introduces
a new property 'steps-per-period'. This property specifies the
number of steps (stable states) produced by the rotary encoder
for each GPIO period.

Hans de Goede 073e570d7c Input: alps - only Dell laptops have separate button bits for v2 dualpoint sticks
It turns out that only Dell laptops have the separate button bits for
v2 dualpoint sticks and that commit 92bac83dd7 ("Input: alps - non
interleaved V2 dualpoint has separate stick button bits") causes
regressions on Toshiba laptops.

This commit adds a check for Dell laptops to the code for handling these
extra button bits, fixing this regression.

This patch has been tested on a Dell Latitude D620 to make sure that it
does not reintroduce the original problem.

Charlie Mooney a736775db6 Input: add MT_TOOL_PALM
Currently there are only two "tools" that can be specified by a multi-touch
driver: MT_TOOL_FINGER and MT_TOOL_PEN. In working with Elan (The touch
vendor) and discussing their next-gen devices it seems that it will be
useful to have more tools so that their devices can give the upper layers
of the stack hints as to what is touching the sensor.

In particular they have new experimental firmware that can better
differentiate between palms vs fingertips and would like to plumb a patch
so that we can use their hints in higher-level gesture soft- ware.  The
firmware on the device can reasonably do a better job of palm detection
because it has access to all of the raw sensor readings as opposed to just
the width/pressure/etc that are exposed by the driver.  As such, the
firmware can characterize what a palm looks like in much finer-grained
detail and this change would allow such a device to share its findings with
the kernel.

Daniel Dressler 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.

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.

David Herrmann 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.

Peter Hutterer 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.

One example of a device using such a switch is the family of Qisda

landscape / portrait orientation of the device. The example in

Justin P. Mattock 0ea6e61122 Documentation: update broken web addresses.
Below you will find an updated version from the original series bunching all patches into one big patch
updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.

Florian Ragwitz e938fbfd4a Input: elantech - ignore high bits in the position coordinates
In older versions of the elantech hardware/firmware those bits always
were unset, so it didn't actually matter, but newer versions seem to
use those high bits for something else, screwing up the coordinates
we report to the input layer for those devices.

Henrik Rydberg 97065e033e Input: clarify the no-finger event in multitouch protocol
The current documentation does not explicitly specify how to report
zero fingers, leaving a potential problem in the driver implementations
and giving no parsing directive to userland. This patch defines two
equally valid ways.

The rotary encoder driver only supports returning input events
for ABS_* axes, this adds support for REL_* axes.  The relative
axis input event is reported as -1 for each counter-clockwise
step and +1 for each clockwise step.

The ability to clamp the position of ABS_* axes between 0 and
a maximum of "steps" has also been added.
