tristate "Input devices (needed for keyboard, mouse, ...)" if EMBEDDED
default y
---help---
Say Y here if you have any input device (mouse, keyboard, tablet,
joystick, steering wheel ...) connected to your system and want
it to be available to applications. This includes standard PS/2
keyboard and mouse.
Say N here if you have a headless (no monitor, no keyboard) system.
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 input.

config INPUT_MOUSEDEV
tristate "Mouse interface" if EMBEDDED
default y
depends on INPUT
---help---
Say Y here if you want your mouse to be accessible as char devices
13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an
emulated IntelliMouse Explorer PS/2 mouse. That way, all user space
programs (includung SVGAlib, GPM and X) will be able to use your
mouse.
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called mousedev.

---help---
Say Y here if you want your mouse also be accessible as char device

the same as the data from /dev/input/mice.

int "Horizontal screen resolution"
depends on INPUT_MOUSEDEV
default "1024"
help
If you're using a digitizer, or a graphic tablet, and want to use
it as a mouse then the mousedev driver needs to know the X window
screen resolution you are using to correctly scale the data. If
you're not using a digitizer, this value is ignored.
config INPUT_MOUSEDEV_SCREEN_Y
int "Vertical screen resolution"
depends on INPUT_MOUSEDEV
default "768"
help
If you're using a digitizer, or a graphic tablet, and want to use
it as a mouse then the mousedev driver needs to know the X window
screen resolution you are using to correctly scale the data. If
you're not using a digitizer, this value is ignored.
config INPUT_JOYDEV
tristate "Joystick interface"
depends on INPUT
---help---
Say Y here if you want your joystick or gamepad to be
accessible as char device 13:0+ - /dev/input/jsX device.
If unsure, say Y.
More information is available: <file:Documentation/input/joystick.txt>
To compile this driver as a module, choose M here: the
module will be called joydev.
config INPUT_TSDEV
tristate "Touchscreen interface"
depends on INPUT
---help---
Say Y here if you have an application that only can understand the
Compaq touchscreen protocol for absolute pointer data. This is
useful namely for embedded configurations.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called tsdev.
config INPUT_TSDEV_SCREEN_X
int "Horizontal screen resolution"
depends on INPUT_TSDEV
default "240"
config INPUT_TSDEV_SCREEN_Y
int "Vertical screen resolution"
depends on INPUT_TSDEV
default "320"
config INPUT_EVDEV
tristate "Event interface"
depends on INPUT
help
Say Y here if you want your input device events be accessible
under char device 13:64+ - /dev/input/eventX in a generic way.
To compile this driver as a module, choose M here: the
module will be called evdev.
config INPUT_EVBUG
tristate "Event debugging"
depends on INPUT
---help---
Say Y here if you have a problem with the input subsystem and
want all events (keypresses, mouse movements), to be output to
the system log. While this is useful for debugging, it's also
a security threat - your keypresses include your passwords, of
course.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called evbug.

config GAMEPORT
tristate "Gameport support"
---help---
Gameport support is for the standard 15-pin PC gameport. If you
have a joystick, gamepad, gameport card, a soundcard with a gameport
or anything else that uses the gameport, say Y or M here and also to
at least one of the hardware specific drivers.
For Ensoniq AudioPCI (ES1370), AudioPCI 97 (ES1371), ESS Solo1,
S3 SonicVibes, Trident 4DWave, SiS7018, and ALi 5451 gameport
support is provided by the sound drivers, so you won't need any
from the below listed modules. You still need to say Y here.
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called gameport.
# Yes, SOUND_GAMEPORT looks a bit odd. Yes, it ends up being turned on
# in every .config. Please don't touch it. It is here to handle an
# unusual dependency between GAMEPORT and sound drivers.
#
# Some sound drivers call gameport functions. If GAMEPORT is
# not selected, empty stubs are provided for the functions and all is
# well.
# If GAMEPORT is built in, everything is fine.
# If GAMEPORT is a module, however, it would need to be loaded for the
# sound driver to be able to link properly. Therefore, the sound
# driver must be a module as well in that case. Since there's no way
# to express that directly in Kconfig, we use SOUND_GAMEPORT to
# express it. SOUND_GAMEPORT boils down to "if GAMEPORT is 'm',
# anything that depends on SOUND_GAMEPORT must be 'm' as well. if
# GAMEPORT is 'y' or 'n', it can be anything".

Say Y here if you have an Amiga with a digital joystick connected
to it.
To compile this driver as a module, choose M here: the
module will be called amijoy.
config JOYSTICK_JOYDUMP
tristate "Gameport data dumper"
depends on INPUT && INPUT_JOYSTICK && GAMEPORT
help
Say Y here if you want to dump data from your joystick into the system
log for debugging purposes. Say N if you are making a production
configuration or aren't sure.
To compile this driver as a module, choose M here: the
module will be called joydump.

/*
* Driver to use Handykey's Twiddler (the first edition, i.e. the one with
* the RS232 interface) as a joystick under Linux
*
* The Twiddler is a one-handed chording keyboard featuring twelve buttons on
* the front, six buttons on the top, and a built-in tilt sensor. The buttons
* on the front, which are grouped as four rows of three buttons, are pressed
* by the four fingers (this implies only one button per row can be held down
* at the same time) and the buttons on the top are for the thumb. The tilt
* sensor delivers X and Y axis data depending on how the Twiddler is held.
* Additional information can be found at http://www.handykey.com.
*
* This driver does not use the Twiddler for its intended purpose, i.e. as
* a chording keyboard, but as a joystick: pressing and releasing a button
* immediately sends a corresponding button event, and tilting it generates
* corresponding ABS_X and ABS_Y events. This turns the Twiddler into a game
* controller with amazing 18 buttons :-)
*
* Note: The Twiddler2 (the successor of the Twiddler that connects directly
* to the PS/2 keyboard and mouse ports) is NOT supported by this driver!
*
* For questions or feedback regarding this driver module please contact:
* Arndt Schoenewald <arndt@quelltext.com>

Say Y here, and a list of supported keyboards will be displayed.
This option doesn't affect the kernel.
If unsure, say Y.

default y
depends on INPUT && INPUT_KEYBOARD
select SERIO
select SERIO_I8042 if PC
select SERIO_GSCPS2 if GSC
help
Say Y here if you want to use a standard AT or PS/2 keyboard. Usually
you'll need this, unless you have a different type keyboard (USB, ADB
or other). This also works for AT and PS/2 keyboards connected over a
PS/2 to serial converter.
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called atkbd.

it with the inputattach program. The connector pinout is
described within lkkbd.c.
To compile this driver as a module, choose M here: the
module will be called lkkbd.
config KEYBOARD_XTKBD

help
Say Y here if you want to use the old IBM PC/XT keyboard (or
compatible) on your system. This is only possible with a
parallel port keyboard adapter, you cannot connect it to the
keyboard port on a PC that runs Linux.
To compile this driver as a module, choose M here: the
module will be called xtkbd.
config KEYBOARD_NEWTON

/*
* LK keyboard driver for Linux, based on sunkbd.c (C) by Vojtech Pavlik
*/
/*
* DEC LK201 and LK401 keyboard driver for Linux (primary for DECstations
* and VAXstations, but can also be used on any standard RS232 with an
* adaptor).
*
* DISCLAIMER: This works for _me_. If you break anything by using the
* information given below, I will _not_ be liable!
*
* RJ11 pinout: To DB9: Or DB25:
* 1 - RxD <----> Pin 3 (TxD) <-> Pin 2 (TxD)
* 2 - GND <----> Pin 5 (GND) <-> Pin 7 (GND)
* 4 - TxD <----> Pin 2 (RxD) <-> Pin 3 (RxD)
* 3 - +12V (from HDD drive connector), DON'T connect to DB9 or DB25!!!
*
* Pin numbers for DB9 and DB25 are noted on the plug (quite small:). For
* RJ11, it's like this:
*
* __=__ Hold the plug in front of you, cable downwards,
* /___/| nose is hidden behind the plug. Now, pin 1 is at
* |1234|| the left side, pin 4 at the right and 2 and 3 are
* |IIII|| in between, of course:)
* | ||
* |____|/
* || So the adaptor consists of three connected cables
* || for data transmission (RxD and TxD) and signal ground.
* Additionally, you have to get +12V from somewhere.
* Most easily, you'll get that from a floppy or HDD power connector.
* It's the yellow cable there (black is ground and red is +5V).
*
* The keyboard and all the commands it understands are documented in
* "VCB02 Video Subsystem - Technical Manual", EK-104AA-TM-001. This
* document is LK201 specific, but LK401 is mostly compatible. It comes
* up in LK201 mode and doesn't report any of the additional keys it
* has. These need to be switched on with the LK_CMD_ENABLE_LK401
* command. You'll find this document (scanned .pdf file) on MANX,
* a search engine specific to DEC documentation. Try
* http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1

default y
depends on INPUT && INPUT_MOUSE
select SERIO
select SERIO_I8042 if PC
select SERIO_GSCPS2 if GSC
---help---
Say Y here if you have a PS/2 mouse connected to your system. This
includes the standard 2 or 3-button PS/2 mouse, as well as PS/2
mice with wheels and extra buttons, Microsoft, Logitech or Genius
compatible.
Synaptics TouchPad users might be interested in a specialized
XFree86 driver at:
http://w1.894.telia.com/~u89404340/touchpad/index.html
and a new verion of GPM at:
http://www.geocities.com/dt_or/gpm/gpm.html
to take advantage of the advanced features of the touchpad.
If unsure, say Y.
To compile this driver as a module, choose M here: the
module will be called psmouse.

its Maple bus.
To compile this driver as a module, choose M here: the
module will be called maplemouse.
config MOUSE_AMIGA
tristate "Amiga mouse"
depends on AMIGA && INPUT && INPUT_MOUSE
help
Say Y here if you have an Amiga and want its native mouse
supported by the kernel.
To compile this driver as a module, choose M here: the
module will be called amimouse.
config MOUSE_RISCPC
tristate "Acorn RiscPC mouse"
depends on ARCH_ACORN && INPUT && INPUT_MOUSE
help
Say Y here if you have the Acorn RiscPC computer and want its
native mouse supported.

depends on INPUT && INPUT_MOUSE
select SERIO
help
Say Y (or M) if you want to use a DEC VSXXX-AA (hockey
puck) or a VSXXX-GA (rectangular) mouse. Theses mice are
typically used on DECstations or VAXstations, but can also
be used on any box capable of RS232 (with some adaptor
described in the source file). This driver also works with the
digitizer (VSXXX-AB) DEC produced.

/*
* Building an adaptor to DB9 / DB25 RS232
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*
* DISCLAIMER: Use this description AT YOUR OWN RISK! I'll not pay for
* anything if you break your mouse, your computer or whatever!
*
* In theory, this mouse is a simple RS232 device. In practice, it has got
* a quite uncommon plug and the requirement to additionally get a power
* supply at +5V and -12V.
*
* If you look at the socket/jack (_not_ at the plug), we use this pin
* numbering:
* _______
* / 7 6 5 \
* | 4 --- 3 |
* \ 2 1 /
* -------
*
* DEC socket DB9 DB25 Note
* 1 (GND) 5 7 -
* 2 (RxD) 2 3 -
* 3 (TxD) 3 2 -
* 4 (-12V) - - Somewhere from the PSU. At ATX, it's
* the thin blue wire at pin 12 of the
* ATX power connector. Only required for
* VSXXX-AA/-GA mice.
* 5 (+5V) - - PSU (red wires of ATX power connector
* on pin 4, 6, 19 or 20) or HDD power
* connector (also red wire).
* 6 (+12V) - - HDD power connector, yellow wire. Only
* required for VSXXX-AB digitizer.
* 7 (dev. avail.) - - The mouse shorts this one to pin 1.
* This way, the host computer can detect
* the mouse. To use it with the adaptor,
* simply don't connect this pin.
*
* So to get a working adaptor, you need to connect the mouse with three
* wires to a RS232 port and two or three additional wires for +5V, +12V and
* -12V to the PSU.
*
* Flow specification for the link is 4800, 8o1.
*
* The mice and tablet are described in "VCB02 Video Subsystem - Technical
* Manual", DEC EK-104AA-TM-001. You'll find it at MANX, a search engine
* specific for DEC documentation. Try
* http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1
