  v4 hardware is a true multitouch capable touchpad (up to 5 fingers).
  The packet format is quite complex, please see protocol document for
  reference.

  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.

  x, y values are actually 12-bit long. Also update protocol document to
  reflect the change.

  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.

  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.

• 2a0bd75e5   Input: psmouse - add support for Elantech touchpads ... Browse Code »

  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.
