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

+ 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 EXPERIMENTAL
+ select BACKLIGHT_CLASS_DEVICE
+ select HWMON
+ select RFKILL
+ ---help---
+ This driver supports the Fn-Fx keys on Eee PC laptops.
+ It also adds the ability to switch camera/wlan on/off.
+
+ If you have an Eee PC laptop, say Y or M here.
+
+
+config ACPI_WMI
+ tristate "WMI (EXPERIMENTAL)"
+ depends on ACPI
+ depends on EXPERIMENTAL
+ 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://sourceforge.net/projects/acpi4asus/>.
+
+ 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
+ select INPUT_POLLDEV
+ select NET
+ select RFKILL
+ 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.
