The touchpad used in the laptop Fujitsu LIFEBOOK E556 is not supported
by the linux kernel yet.
The driver input/mouse/elantech.c provides already support for some other
Fujitsu LIFEBOOK types. The same support is needed for "LIFEBOOK E556" too.
After adding a similar section related to "LIFEBOOK E556" the touchpad works
fine.
The values for the firmware version and Synaptics capabilities are taken
from the kernel boot messages:
elantech: assuming hardware version 4 (with firmware version 0x570f01)
elantech: Synaptics capabilities query result 0xc0, 0x14, 0x0c.
The touchpad has two hardware buttons.
