Additionally to the properties specified in the above standards a host bridge
driver implementation may support the following properties:
- linux,pci-domain:
If present this property assigns a fixed PCI domain number to a host bridge,
otherwise an unstable (across boots) unique number will be assigned.
It is required to either not set this property at all or set it for all
host bridges in the system, otherwise potentially conflicting domain numbers
may be assigned to root buses behind different host bridges. The domain
number for each host bridge in the system must be unique.

Currently the Linux Elantech touchpad driver is aware of two different

Currently the Linux Elantech touchpad driver is aware of four different
hardware versions unimaginatively called version 1,version 2, version 3
and version 4. Version 1 is found in "older" laptops and uses 4 bytes per
packet. Version 2 seems to be introduced with the EeePC and uses 6 bytes
per packet, and provides additional features such as position of two fingers,
and width of the touch. Hardware version 3 uses 6 bytes per packet (and
for 2 fingers the concatenation of two 6 bytes packets) and allows tracking
of up to 3 fingers. Hardware version 4 uses 6 bytes per packet, and can
combine a status packet with multiple head or motion packets. Hardware version
4 allows tracking up to 5 fingers.
Some Hardware version 3 and version 4 also have a trackpoint which uses a
separate packet format. It is also 6 bytes per packet.
The driver tries to support both hardware versions and should be compatible
with the Xorg Synaptics touchpad driver and its graphical configuration
utilities.
Note that a mouse button is also associated with either the touchpad or the
trackpoint when a trackpoint is available. Disabling the Touchpad in xorg
(TouchPadOff=0) will also disable the buttons associated with the touchpad.
Additionally the operation of the touchpad can be altered by adjusting the
contents of some of its internal registers. These registers are represented
by the driver as sysfs entries under /sys/bus/serio/drivers/psmouse/serio?
