Say Yes here if you have any input device that uses serial I/O to
communicate with the system. This includes the
* standard AT keyboard and PS/2 mouse *
as well as serial mice, Sun keyboards, some joysticks and 6dof
devices and more.
If unsure, say Y.
To compile this driver as a module, choose M here: the

---help---
i8042 is the chip over which the standard AT keyboard and PS/2
mouse are connected to the computer. If you use these devices,
you'll need to say Y here.
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called i8042.
config SERIO_SERPORT
tristate "Serial port line discipline"
default y
depends on SERIO
---help---
Say Y here if you plan to use an input device (mouse, joystick,
tablet, 6dof) that communicates over the RS232 serial (COM) port.
More information is available: <file:Documentation/input/input.txt>
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called serport.

equipped with the ct82c710 chip and want to use a mouse connected
to the "QuickPort".
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called ct82c710.

If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called parkbd.

depends on SERIO
help
Say Y here if you want to have raw access to serio ports, such as
AUX ports on i8042 keyboard controller. Each serio port that is
bound to this driver will be accessible via a char device with
major 10 and dynamically allocated minor. The driver will try
allocating minor 1 (that historically corresponds to /dev/psaux)
first. To bind this driver to a serio port use sysfs interface:
echo -n "serio_raw" > /sys/bus/serio/devices/serioX/driver
To compile this driver as a module, choose M here: the
module will be called serio_raw.
