Input: elantech - fix touchpad initialization on Gigabyte U2442

2014-06-07T17:28:20+00:00

commit 36189cc3cd57ab0f1cd75241f93fe01de928ac06 upstream.

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.

Input: fix typos in Documentation/input/gamepad.txt

2013-12-18T16:47:43+00:00

Fix some typos and while at it also use "PS" as the name for the central
"HOME" button on Sony controllers, this is how Sony itself calls it.

Input: joystick - use sizeof(VARIABLE) in documentation

2013-12-16T10:13:35+00:00

Use the preferred style sizeof(VARIABLE) instead of sizeof(TYPE) in the
joystick API documentation, Documentation/CodingStyle states that this
is the preferred style for allocations but using it elsewhere is good
too.

Also fix some errors like "sizeof(struct mybuffer)" which didn't mean
anything.

Input: joystick - refer to /dev/input/js0 in documentation

2013-12-16T10:13:32+00:00

Nowadays the joystick device nodes are created under /dev/input, reflect
this in the documentation in order to make copy and paste easier for
users.

Input: clarify gamepad API ABS values

2013-10-16T06:42:07+00:00

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.

input: document gamepad API and add extra keycodes

2013-08-20T10:31:35+00:00

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.

Input: MT - Specify that ABS_MT_SLOT must have a minimum of 0

2013-06-13T19:32:00+00:00

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.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:
 "Except for the largish change to the ALPS driver adding "Dolphin V1"
  support and Wacom getting a new signature of yet another device, the
  rest are straightforward driver fixes."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: mms114 - Fix regulator enable and disable paths
  Input: ads7864 - check return value of regulator enable
  Input: tc3589x-keypad - fix keymap size
  Input: wacom - add support for 0x10d
  Input: ALPS - update documentation for recent touchpad driver mods
  Input: ALPS - add "Dolphin V1" touchpad support
  Input: ALPS - remove unused argument to alps_enter_command_mode()
  Input: cypress_ps2 - fix trackpadi found in Dell XPS12

Input: ALPS - update documentation for recent touchpad driver mods

2013-02-24T04:09:24+00:00

Updated documentation for the new ALPS touchpad support submitted in two
patchsets by Kevin Cernekee.  My understanding is the most recent
patchset '"Dolphin V2" touchpad support' may still need some work but
Future work on the ALPS driver should not impact these documentation changes.
