[PATCH 0/2 v2] elantech: Additional info reporting with version 2

[Éric Piel]

Hello,

Will follow a second version of my patches to support more information
in the hardware version 2 of elantech. The main changes is that I've
done much further reverse engineering on the protocol, and found out that:
 * the width is acutally reported on 6 bits (not just 4)
 * the coordinates of the three finger touch are rerported as a one
finger touch
 * it's possible to differentiate between 3 and 4 fingers touch

The second patch to add MT support has only be adapted to work better
with mousedev, as suggested by Dmitry.

Patches are against git input-linux for-linus.

See you,
Eric

Hi Dmitry,
These two patches were not in your queue for 2.6.35-rc0. Is there any
additional changes that you'd like to have on them before merging?

Cheers,
Eric

Eric,

It is still unclear to me what is the cutoff version of the firmware
that starts reporting teh width and multiple fingers. I think that
we should not advertise these capabilities on touchpads that do not
support them.

So basically more testing/data is needed at this point.
