Hi Florian,

This patch adds support for the built-in multitouch sensor in the Samsung
SUR40 touchscreen device, also known as Microsoft Surface 2.0 or Microsoft
Pixelsense. Support for raw video output from the sensor as well as the 
accelerometer will be added in a later patch.

The driver looks pretty good now, thanks for making the changes. There
might be one or two white space problems, but those can be fixed while
applying. Dmitry, I guess you want to take this through your tree, so
