        select NEW_LEDS
        select LEDS_CLASS
        ---help---
          This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
          support for Fn-Fx key combinations, Bluetooth control, video
          output switching, ThinkLight control, UltraBay eject and more.
          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.

          Extra functionality will be available if the rfkill (CONFIG_RFKILL)
          and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
          Note that if you want ThinkPad-ACPI to be built-in instead of
          modular, ALSA and rfkill will also have to be built-in.

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

config THINKPAD_ACPI_ALSA_SUPPORT
        bool "Console audio control ALSA interface"
        depends on THINKPAD_ACPI
        depends on SND
        depends on SND = y || THINKPAD_ACPI = SND
        default y
        ---help---
          Enables monitoring of the built-in console audio output control
          (headphone and speakers), which is operated by the mute and (in
          some ThinkPad models) volume hotkeys.

          If this option is enabled, ThinkPad-ACPI will export an ALSA card
          with a single read-only mixer control, which should be used for
          on-screen-display feedback purposes by the Desktop Environment.

          Optionally, the driver will also allow software control (the
          ALSA mixer will be made read-write).  Please refer to the driver
          documentation for details.

          All IBM models have both volume and mute control.  Newer Lenovo
          models only have mute control (the volume hotkeys are just normal
          keys and volume control is done through the main HDA mixer).

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_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---

        select LEDS_CLASS
        select NEW_LEDS
        ---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 MSI_WMI

        help
         Say Y here if you want to support WMI-based hotkeys on MSI laptops.

         To compile this driver as a module, choose M here: the module will
         be called msi-wmi.

config ACPI_ASUS
        tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
        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.

        ---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.

          This driver adds support for Bluetooth events for the RFKill
          switch on modern Toshiba laptops with full ACPI support and
          an RFKill switch.

          This driver handles RFKill events for the TOS6205 Bluetooth,
          and re-enables it when the switch is set back to the 'on'
          position.
