	---help---
	  This option enables device driver support for in-band access to the
	  IBM RSA (Condor) service processor in eServer xSeries systems.
	  The ibmasm device driver allows user space application to access
	  ASM (Advanced Systems Management) functions on the service
	  processor. The driver is meant to be used in conjunction with
	  a user space API.
	  The ibmasm driver also enables the OS to use the UART on the
	  service processor board as a regular serial port. To make use of
	  this feature serial driver support (CONFIG_SERIAL_8250) must be
	  enabled.

	  WARNING: This software may not be supported or function
	  correctly on your IBM server. Please consult the IBM ServerProven

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_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 "Suport 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 ATMEL_SSC
	tristate "Device driver for Atmel SSC peripheral"
	depends on AVR32 || ARCH_AT91
	---help---
	  This option enables device driver support for Atmel Syncronized
	  Serial Communication peripheral (SSC).

	  The SSC peripheral supports a wide variety of serial frame based
	  communications, i.e. I2S, SPI, etc.

	  If unsure, say N.

config INTEL_MENLOW
	tristate "Thermal Management driver for Intel menlow platform"
	depends on ACPI_THERMAL
	depends on X86
	---help---
	  ACPI thermal management enhancement driver on
	  Intel Menlow platform.

	  If unsure, say N.

config ENCLOSURE_SERVICES
	tristate "Enclosure Services"
	default n
	help
	  Provides support for intelligent enclosures (bays which
	  contain storage devices).  You also need either a host
	  driver (SCSI/ATA) which supports enclosures
	  or a SCSI enclosure device (SES) to use these services.
