2011-05-16Input: elantech - describe further the protocolÉric Piel
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.

2010-05-03Input: elantech - ignore high bits in the position coordinatesFlorian Ragwitz
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.

2008-10-16Input: psmouse - add support for Elantech touchpadsArjan Opmeer
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.
