Add support for the new T100 object which replaces the previous
T9 multitouch touchscreen object in recent maXTouch devices.
T100 provides improved reporting with selectable auxiliary
information, and a type field for hover/stylus/glove reporting.
The hovering finger support was based on Chung-Yih's work in
the ChromiumOS downstream kernel:

Having this patch in mainline as commit
b23157dc74272ac8ebffd1a566e3e822dbc3e65f [1] breaks our Atmel touch.
It seems that above
+ set_bit(EV_ABS, input_dev->evbit);
is missing in the version which went into mainline? Re-adding it makes
it work for us, again.
Opinions?
Best regards
Dirk
