Input: create a book with Linux Input documentation

2017-04-05T22:45:07+00:00

Now that all files under Documentation/input follows the ReST markup language, rename them to *.rst and create a book for the Linux Input subsystem. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Dmitry Torokhov

Input: elantech - convert documentation into ReST format

2017-04-05T22:44:13+00:00

This file require minimum adjustments to be a valid ReST file. Do it, in order to be able to parse it with Sphinx. We opted to remove section numbers, as this can be automatically generated on Sphinx, by using :numbered: tag at index. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Dmitry Torokhov

Input: elantech - update the documentation

2014-11-14T01:50:23+00:00

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.

Input: elantech - fix touchpad initialization on Gigabyte U2442

2014-05-05T19:34:22+00:00

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 Tested-by: Philipp Wolfer Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: elantech - add v4 hardware support

2011-09-09T17:35:02+00:00

v4 hardware is a true multitouch capable touchpad (up to 5 fingers). The packet format is quite complex, please see protocol document for reference. Signed-off-by: JJ Ding Signed-off-by: Dmitry Torokhov

Input: elantech - add v3 hardware support

2011-09-09T17:34:58+00:00

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. Signed-off-by: JJ Ding Acked-by: Daniel Kurtz Acked-by: Éric Piel Signed-off-by: Dmitry Torokhov

Input: elantech - correct x, y value range for v2 hardware

2011-09-09T17:34:25+00:00

x, y values are actually 12-bit long. Also update protocol document to reflect the change. Signed-off-by: JJ Ding Acked-by: Daniel Kurtz Acked-by: Éric Piel Signed-off-by: Dmitry Torokhov

Input: elantech - describe further the protocol

2011-05-17T05:48:24+00:00

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. Signed-off-by: Éric Piel Reviewed-by: Henrik Rydberg Signed-off-by: Dmitry Torokhov

Input: elantech - ignore high bits in the position coordinates

2010-05-04T06:35:11+00:00

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.

Input: psmouse - add support for Elantech touchpads

2008-10-17T02:54:35+00:00

This is version 5 of the driver. Relative mode support has been dropped (users wishing to use touchpad in relative mode can use standard PS/2 protocol emulation done in hardware). The driver supports both original version of Elantech protocol and the newer one used by touchpads installed in EeePC. Signed-off-by: Arjan Opmeer Signed-off-by: Dmitry Torokhov
