	  For more information about this driver see
	  <file:Documentation/laptops/thinkpad-acpi.txt> and
	  <http://ibm-acpi.sf.net/> .

	  This driver was formerly known as ibm-acpi.

	  If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.

config THINKPAD_ACPI_DEBUGFACILITIES
	bool "Maintainer debug facilities"
	depends on THINKPAD_ACPI
	default n
	---help---
	  Enables extra stuff in the thinkpad-acpi which is completely useless
	  for normal use.  Read the driver source to find out what it does.

	  Say N here, unless you were told by a kernel maintainer to do
	  otherwise.

config THINKPAD_ACPI_DEBUG
	bool "Verbose debug mode"
	depends on THINKPAD_ACPI
	default n
	---help---
	  Enables extra debugging information, at the expense of a slightly
	  increase in driver size.

	  If you are not sure, say N here.

config THINKPAD_ACPI_UNSAFE_LEDS
	bool "Allow control of important LEDs (unsafe)"
	depends on THINKPAD_ACPI
	default n
	---help---
	  Overriding LED state on ThinkPads can mask important
	  firmware alerts (like critical battery condition), or misled
	  the user into damaging the hardware (undocking or ejecting
	  the bay while buses are still active), etc.

	  LED control on the ThinkPad is write-only (with very few
	  exceptions on very ancient models), which makes it
	  impossible to know beforehand if important information will
	  be lost when one changes LED state.

	  Users that know what they are doing can enable this option
	  and the driver will allow control of every LED, including
	  the ones on the dock stations.

	  Never enable this option on a distribution kernel.

	  Say N here, unless you are building a kernel for your own
	  use, and need to control the important firmware LEDs.

config THINKPAD_ACPI_DOCK
	bool "Legacy Docking Station Support"
	depends on THINKPAD_ACPI
	depends on ACPI_DOCK=n
	default n
	---help---
	  Allows the thinkpad_acpi driver to handle docking station events.
	  This support was made obsolete by the generic ACPI docking station
	  support (CONFIG_ACPI_DOCK).  It will allow locking and removing the
	  laptop from the docking station, but will not properly connect PCI
	  devices.

	  If you are not sure, say N here.

config THINKPAD_ACPI_BAY
	bool "Legacy Removable Bay Support"
	depends on THINKPAD_ACPI
	default y
	---help---
	  Allows the thinkpad_acpi driver to handle removable bays.  It will
	  electrically disable the device in the bay, and also generate
	  notifications when the bay lever is ejected or inserted.

	  If you are not sure, say Y here.

config THINKPAD_ACPI_VIDEO
	bool "Video output control support"
	depends on THINKPAD_ACPI
	default y
	---help---
	  Allows the thinkpad_acpi driver to provide an interface to control
	  the various video output ports.

	  This feature often won't work well, depending on ThinkPad model,
	  display state, video output devices in use, whether there is a X
	  server running, phase of the moon, and the current mood of
	  Schroedinger's cat.  If you can use X.org's RandR to control
	  your ThinkPad's video output ports instead of this feature,
	  don't think twice: do it and say N here to save some memory.

	  If you are not sure, say Y here.

config THINKPAD_ACPI_HOTKEY_POLL
	bool "Support NVRAM polling for hot keys"
	depends on THINKPAD_ACPI
	default y
	---help---
	  Some thinkpad models benefit from NVRAM polling to detect a few of
	  the hot key press events.  If you know your ThinkPad model does not
	  need to do NVRAM polling to support any of the hot keys you use,
	  unselecting this option will save about 1kB of memory.

	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
	  unlikely to need NVRAM polling in their latest BIOS versions.

	  NVRAM polling can detect at most the following keys: ThinkPad/Access
	  IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
	  Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

	  If you are not sure, say Y here.  The driver enables polling only if
	  it is strictly necessary to do so.

config INTEL_MENLOW
	tristate "Thermal Management driver for Intel menlow platform"
	depends on ACPI_THERMAL
	select THERMAL
	---help---
	  ACPI thermal management enhancement driver on
	  Intel Menlow platform.

	  If unsure, say N.

config EEEPC_LAPTOP
	tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
	depends on ACPI
	depends on INPUT
	depends on EXPERIMENTAL
	depends on RFKILL || RFKILL = n
	select BACKLIGHT_CLASS_DEVICE
	select HWMON
	---help---
	  This driver supports the Fn-Fx keys on Eee PC laptops.

	  It  also gives access to some extra laptop functionalities like
	  Bluetooth, backlight and allows powering on/off some other
	  devices.

	  If you have an Eee PC laptop, say Y or M here.


config ACPI_WMI
	tristate "WMI"
	depends on ACPI
	help
	  This driver adds support for the ACPI-WMI (Windows Management
	  Instrumentation) mapper device (PNP0C14) found on some systems.

	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
	  ACPI firmware to userspace - this is done through various vendor
	  defined methods and data blocks in a PNP0C14 device, which are then
	  made available for userspace to call.

	  The implementation of this in Linux currently only exposes this to
	  other kernel space drivers.

	  This driver is a required dependency to build the firmware specific
	  drivers needed on many machines, including Acer and HP laptops.

	  It is safe to enable this driver even if your DSDT doesn't define
	  any ACPI-WMI devices.

config ACPI_ASUS
	tristate "ASUS/Medion Laptop Extras"
	depends on ACPI
	select BACKLIGHT_CLASS_DEVICE
	---help---
	  This driver provides support for extra features of ACPI-compatible
	  ASUS laptops. As some of Medion laptops are made by ASUS, it may also
	  support some Medion laptops (such as 9675 for example).  It makes all
	  the extra buttons generate standard ACPI events that go through
	  /proc/acpi/events, and (on some models) adds support for changing the
	  display brightness and output, switching the LCD backlight on and off,
	  and most importantly, allows you to blink those fancy LEDs intended
	  for reporting mail and wireless status.

	  Note: display switching code is currently considered EXPERIMENTAL,
	  toying with these values may even lock your machine.

	  All settings are changed via /proc/acpi/asus directory entries. Owner
	  and group for these entries can be set with asus_uid and asus_gid
	  parameters.

	  More information and a userspace daemon for handling the extra buttons
	  at <http://acpi4asus.sf.net>.

	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
	  driver is still under development, so if your laptop is unsupported or
	  something works not quite as expected, please use the mailing list
	  available on the above page (acpi4asus-user@lists.sourceforge.net).

	  NOTE: This driver is deprecated and will probably be removed soon,
	  use asus-laptop instead.

config ACPI_TOSHIBA
	tristate "Toshiba Laptop Extras"
	depends on ACPI
	depends on INPUT
	depends on RFKILL || RFKILL = n
	select INPUT_POLLDEV
	select BACKLIGHT_CLASS_DEVICE
	---help---
	  This driver adds support for access to certain system settings
	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
	  their lack of a BIOS setup menu and APM support.

	  On these machines, all system configuration is handled through the
	  ACPI.  This driver is required for access to controls not covered
	  by the general ACPI drivers, such as LCD brightness, video output,
	  etc.

	  This driver differs from the non-ACPI Toshiba laptop driver (located
	  under "Processor type and features") in several aspects.
	  Configuration is accessed by reading and writing text files in the
	  /proc tree instead of by program interface to /dev.  Furthermore, no
	  power management functions are exposed, as those are handled by the
	  general ACPI drivers.

	  More information about this driver is available at
	  <http://memebeam.org/toys/ToshibaAcpiDriver>.

	  If you have a legacy free Toshiba laptop (such as the Libretto L1
	  series), say Y.

	261	Overriding LED state on ThinkPads can mask important

	263	the user into damaging the hardware (undocking or ejecting
	264	the bay while buses are still active), etc.
	265
	266	LED control on the ThinkPad is write-only (with very few

	270
	271	Users that know what they are doing can enable this option
	272	and the driver will allow control of every LED, including

	312
	313	This feature often won't work well, depending on ThinkPad model,
	314	display state, video output devices in use, whether there is a X
	315	server running, phase of the moon, and the current mood of
	316	Schroedinger's cat. If you can use X.org's RandR to control
	317	your ThinkPad's video output ports instead of this feature,

	325	default y
	326	---help---
	327	Some thinkpad models benefit from NVRAM polling to detect a few of
	328	the hot key press events. If you know your ThinkPad model does not
	329	need to do NVRAM polling to support any of the hot keys you use,
	330	unselecting this option will save about 1kB of memory.
	331
	332	ThinkPads T40 and newer, R52 and newer, and X31 and newer are
	333	unlikely to need NVRAM polling in their latest BIOS versions.
	334
	335	NVRAM polling can detect at most the following keys: ThinkPad/Access
	336	IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
	337	Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

	374	This driver adds support for the ACPI-WMI (Windows Management
	375	Instrumentation) mapper device (PNP0C14) found on some systems.
	376
	377	ACPI-WMI is a proprietary extension to ACPI to expose parts of the
	378	ACPI firmware to userspace - this is done through various vendor
	379	defined methods and data blocks in a PNP0C14 device, which are then
	380	made available for userspace to call.
	381
	382	The implementation of this in Linux currently only exposes this to
	383	other kernel space drivers.
	384
	385	This driver is a required dependency to build the firmware specific
	386	drivers needed on many machines, including Acer and HP laptops.
	387
	388	It is safe to enable this driver even if your DSDT doesn't define

	396	This driver provides support for extra features of ACPI-compatible
	397	ASUS laptops. As some of Medion laptops are made by ASUS, it may also
	398	support some Medion laptops (such as 9675 for example). It makes all
	399	the extra buttons generate standard ACPI events that go through
	400	/proc/acpi/events, and (on some models) adds support for changing the
	401	display brightness and output, switching the LCD backlight on and off,
	402	and most importantly, allows you to blink those fancy LEDs intended
	403	for reporting mail and wireless status.
	404
	405	Note: display switching code is currently considered EXPERIMENTAL,
	406	toying with these values may even lock your machine.
	407
	408	All settings are changed via /proc/acpi/asus directory entries. Owner
	409	and group for these entries can be set with asus_uid and asus_gid
	410	parameters.

	430	---help---
	431	This driver adds support for access to certain system settings
	432	on "legacy free" Toshiba laptops. These laptops can be recognized by
	433	their lack of a BIOS setup menu and APM support.
	434
	435	On these machines, all system configuration is handled through the
	436	ACPI. This driver is required for access to controls not covered
	437	by the general ACPI drivers, such as LCD brightness, video output,
	438	etc.
	439
	440	This driver differs from the non-ACPI Toshiba laptop driver (located
	441	under "Processor type and features") in several aspects.
	442	Configuration is accessed by reading and writing text files in the
	443	/proc tree instead of by program interface to /dev. Furthermore, no
	444	power management functions are exposed, as those are handled by the
	445	general ACPI drivers.
	446
	447	More information about this driver is available at
	448	<http://memebeam.org/toys/ToshibaAcpiDriver>.
