	help
	  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
	  module will be called serio.

config ARCH_MIGHT_HAVE_PC_SERIO
	bool
	help
	  Select this config option from the architecture Kconfig if
	  the architecture might use a PC serio device (i8042) to
	  communicate with keyboard, mouse, etc.

if SERIO

config SERIO_I8042
	tristate "i8042 PC Keyboard controller"
	default y
	depends on ARCH_MIGHT_HAVE_PC_SERIO
	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 TTY
	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.rst>

	  If unsure, say Y.

	  To compile this driver as a module, choose M here: the

	depends on GSC
	default y
	help
	  This driver provides support for the PS/2 ports on PA-RISC machines
	  over which HP PS/2 keyboards and PS/2 mice may be connected.
	  If you use these devices, you'll need to say Y here.

	  It's safe to enable this driver, so if unsure, say Y.

config SERIO_GSCPS2_RDI_KEYCODES
	bool "Use PrecisionBook keyboard scancodes"
	depends on SERIO_GSCPS2
	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 HP_SDC
	tristate "HP System Device Controller i8042 Support"
	depends on (GSC || HP300) && SERIO
	default y
	help
	  This option enables support for the "System Device
	  Controller", an i8042 carrying microcode to manage a
	  few miscellaneous devices on some Hewlett Packard systems.
	  The SDC itself contains a 10ms resolution timer/clock capable
	  of delivering interrupts on a periodic and one-shot basis.
	  The SDC may also be connected to a battery-backed real-time
	  clock, a basic audio waveform generator, and an HP-HIL Master
	  Link Controller serving up to seven input devices.

	  By itself this option is rather useless, but enabling it will
	  enable selection of drivers for the abovementioned devices.
	  It is, however, incompatible with the old, reliable HIL keyboard
	  driver, and the new HIL driver is experimental, so if you plan
	  to use a HIL keyboard as your primary keyboard, you may wish
	  to keep using that driver until the new HIL drivers have had
	  more testing.

config SERIO_RAW
	tristate "Raw access to serio ports"
	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/drvctl

	  To compile this driver as a module, choose M here: the

	  or any standard AT keyboard connected to the mailboard port.

	  When used for the E3 mailboard, a non-standard key table
	  must be loaded from userspace, possibly using udev extras
	  provided keymap helper utility.

	  To compile this driver as a module, choose M here;
	  the module will be called ams_delta_serio.
