menuconfig INPUT_KEYBOARD
bool "Keyboards" if EMBEDDED || !X86
default y
help
Say Y here, and a list of supported keyboards will be displayed.
This option doesn't affect the kernel.
If unsure, say Y.
if INPUT_KEYBOARD
config KEYBOARD_ATKBD
tristate "AT keyboard" if EMBEDDED || !X86_PC
default y
select SERIO
select SERIO_LIBPS2
select SERIO_I8042 if X86_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.
config KEYBOARD_ATKBD_HP_KEYCODES
bool "Use HP keyboard scancodes"
depends on PARISC && KEYBOARD_ATKBD
default y
help
Say Y here if you have a PA-RISC machine and want to use an AT or
PS/2 keyboard, and your keyboard uses keycodes that are specific to
PA-RISC keyboards.
Say N if you use a standard keyboard.
config KEYBOARD_ATKBD_RDI_KEYCODES
bool "Use PrecisionBook keyboard scancodes"
depends on KEYBOARD_ATKBD_HP_KEYCODES
default n
help
If you have an RDI PrecisionBook, say Y here if you want to use its
built-in keyboard (as opposed to an external keyboard).
The PrecisionBook has five keys that conflict with those used by most
AT and PS/2 keyboards. These are as follows:
PrecisionBook Standard AT or PS/2
F1 F12
Left Ctrl Left Alt
Caps Lock Left Ctrl
Right Ctrl Caps Lock
Left 102nd key (the key to the right of Left Shift)
If you say N here, and use the PrecisionBook keyboard, then each key
in the left-hand column will be interpreted as the corresponding key
in the right-hand column.
If you say Y here, and use an external keyboard, then each key in the
right-hand column will be interpreted as the key shown in the
left-hand column.
config KEYBOARD_SUNKBD
tristate "Sun Type 4 and Type 5 keyboard"
select SERIO
help
Say Y here if you want to use a Sun Type 4 or Type 5 keyboard,
connected either to the Sun keyboard connector or to an serial
(RS-232) port via a simple adapter.
To compile this driver as a module, choose M here: the
module will be called sunkbd.
config KEYBOARD_LKKBD
tristate "DECstation/VAXstation LK201/LK401 keyboard"
select SERIO
help
Say Y here if you want to use a LK201 or LK401 style serial
keyboard. This keyboard is also useable on PCs if you attach
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_LOCOMO
tristate "LoCoMo Keyboard Support"
depends on SHARP_LOCOMO && INPUT_KEYBOARD
help
Say Y here if you are running Linux on a Sharp Zaurus Collie or Poodle based PDA
To compile this driver as a module, choose M here: the
module will be called locomokbd.
config KEYBOARD_XTKBD
tristate "XT keyboard"
select SERIO
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
tristate "Newton keyboard"
select SERIO
help
Say Y here if you have a Newton keyboard on a serial port.
To compile this driver as a module, choose M here: the
module will be called newtonkbd.
config KEYBOARD_STOWAWAY
tristate "Stowaway keyboard"
select SERIO
help
Say Y here if you have a Stowaway keyboard on a serial port.
Stowaway compatible keyboards like Dicota Input-PDA keyboard
are also supported by this driver.
To compile this driver as a module, choose M here: the
module will be called stowaway.
config KEYBOARD_CORGI
tristate "Corgi keyboard"
depends on PXA_SHARPSL
default y
help
Say Y here to enable the keyboard on the Sharp Zaurus SL-C7xx
series of PDAs.
To compile this driver as a module, choose M here: the
module will be called corgikbd.
config KEYBOARD_SPITZ
tristate "Spitz keyboard"
depends on PXA_SHARPSL
default y
help
Say Y here to enable the keyboard on the Sharp Zaurus SL-C1000,
SL-C3000 and Sl-C3100 series of PDAs.
To compile this driver as a module, choose M here: the
module will be called spitzkbd.
config KEYBOARD_AMIGA
tristate "Amiga keyboard"
depends on AMIGA
help
Say Y here if you are running Linux on any AMIGA and have a keyboard
attached.
To compile this driver as a module, choose M here: the
module will be called amikbd.
config KEYBOARD_HIL_OLD
tristate "HP HIL keyboard support (simple driver)"
depends on GSC || HP300
default y
help
The "Human Interface Loop" is a older, 8-channel USB-like
controller used in several Hewlett Packard models. This driver
was adapted from the one written for m68k/hp300, and implements
support for a keyboard attached to the HIL port, but not for
any other types of HIL input devices like mice or tablets.
However, it has been thoroughly tested and is stable.
If you want full HIL support including support for multiple
keyboards, mice, and tablets, you have to enable the
"HP System Device Controller i8042 Support" in the input/serio
submenu.
config KEYBOARD_HIL
tristate "HP HIL keyboard support"
depends on GSC || HP300
default y
select HP_SDC
select HIL_MLC
select SERIO
help
The "Human Interface Loop" is a older, 8-channel USB-like
controller used in several Hewlett Packard models.
This driver implements support for HIL-keyboards attached
to your machine, so normally you should say Y here.
config KEYBOARD_OMAP
tristate "TI OMAP keypad support"
depends on (ARCH_OMAP1 || ARCH_OMAP2)
help
Say Y here if you want to use the OMAP keypad.
To compile this driver as a module, choose M here: the
module will be called omap-keypad.
config KEYBOARD_AAED2000
tristate "AAED-2000 keyboard"
depends on MACH_AAED2000
default y
help
Say Y here to enable the keyboard on the Agilent AAED-2000
development board.
To compile this driver as a module, choose M here: the
module will be called aaed2000_kbd.
config KEYBOARD_GPIO
tristate "GPIO Buttons"
depends on GENERIC_GPIO
help
This driver implements support for buttons connected
to GPIO pins of various CPUs (and some other chips).
Say Y here if your device has buttons connected
directly to such GPIO pins. Your board-specific
setup logic must also provide a platform device,
with configuration data saying which GPIOs are used.
To compile this driver as a module, choose M here: the
module will be called gpio-keys.
config KEYPAD_S3C
tristate "S3C keypad support"
depends on (CPU_S3C6400 || CPU_S3C6410)
default n
help
Say Y here if you want to use the S3C SMDK keypad.
To compile this driver as a module, choose M here: the
module will be called s3c-keypad.
#Qisda Tony 090324, add keypad [
config KEYPAD_S3C_QISDA
tristate "S3C keypad support for Qisda use"
default n
help
Say Y here if you want to use the menu key for Qisda use
tony.yc.huang@qisda.com
#Qisda Tony 090324, add keypad ]

/*
* 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!
*
* RJ10 pinout: To DE9: 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 DE9 or DB25!!!
*
* Pin numbers for DE9 and DB25 are noted on the plug (quite small:). For
* RJ10, 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
