2014-12-05Input: xpad - update docs to reflect current stateDaniel Dressler1-40/+83
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. Signed-off-by: Daniel Dressler <danieru.dressler@gmail.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

A chapter is added to describe the trackpoint packets. A section is added to describe the behaviour of the knob crc_enabled in sysfs. The introduction of the documentation only mentioned v1/v2, but in the last part it already contains explanation of v3 and v4. The introduction is updated.

2014-05-05Input: elantech - fix touchpad initialization on Gigabyte U2442Hans de Goede1-1/+4
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. https://bugzilla.kernel.org/show_bug.cgi?id=61151 Cc: stable@vger.kernel.org Reported-by: Philipp Wolfer <ph.wolfer@gmail.com> Tested-by: Philipp Wolfer <ph.wolfer@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

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.

2013-08-20input: document gamepad API and add extra keycodesDavid Herrmann1-0/+156
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.

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.
