-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).

- *   bluetooth - Bluetooth subsystem state: contains 0 or 1 (rw)

- * In addition to these platform device attributes the driver

- * This driver might work on other laptops produced by Compal. If you

-/*
- * fujitsu-laptop.c - Fujitsu laptop support, providing access to additional
- * features made available on a range of Fujitsu laptops including the
- * P2xxx/P5xxx/S6xxx/S7xxx series.
- *
- * This driver exports a few files in /sys/devices/platform/fujitsu-laptop/;
- * others may be added at a later date.
- *
- *   lcd_level - Screen brightness: contains a single integer in the
- *   range 0..7. (rw)
- *
- * In addition to these platform device attributes the driver
- * registers itself in the Linux backlight control subsystem and is
- * available to userspace under /sys/class/backlight/fujitsu-laptop/.
- *
- * Hotkeys present on certain Fujitsu laptops (eg: the S6xxx series) are
- * also supported by this driver.
- *
- * This driver has been tested on a Fujitsu Lifebook S6410, S7020 and
- * P8010.  It should work on most P-series and S-series Lifebooks, but
- * YMMV.
- *
- * The module parameter use_alt_lcd_levels switches between different ACPI
- * brightness controls which are used by different Fujitsu laptops.  In most

- * msi-laptop.c - MSI S270 laptop support. This laptop is sold under
- * various brands, including "Cytron/TCM/Medion/Tchibo MD96100".
- *
- * Driver also supports S271, S420 models.
- *
- * This driver exports a few files in /sys/devices/platform/msi-laptop-pf/:
- *
- *   lcd_level - Screen brightness: contains a single integer in the
- *   range 0..8. (rw)
- *
- *   auto_brightness - Enable automatic brightness control: contains
- *   either 0 or 1. If set to 1 the hardware adjusts the screen
- *   brightness automatically when the power cord is
- *   plugged/unplugged. (rw)
- *
- *   wlan - WLAN subsystem enabled: contains either 0 or 1. (ro)
- *
- *   bluetooth - Bluetooth subsystem enabled: contains either 0 or 1
- *   Please note that this file is constantly 0 if no Bluetooth
- *   hardware is available. (ro)
- *
- * In addition to these platform device attributes the driver
- * registers itself in the Linux backlight control subsystem and is
- * available to userspace under /sys/class/backlight/msi-laptop-bl/.
- *
- * This driver might work on other laptops produced by MSI. If you
- * want to try it you can pass force=1 as argument to the module which
- * will force it to load even when the DMI data doesn't identify the
- * laptop as MSI S270. YMMV.

- *
- *      Aug.20, 2004    David Bronaugh <dbronaugh@linuxboxen.org>
- *              - v0.6  Correct brightness controls to reflect reality
- *                      based on information gleaned by Hiroshi Miura
- *                      and discussions with Hiroshi Miura
- *
- *	Aug.10, 2004	Hiroshi Miura <miura@da-cha.org>
- *		- v0.5  support LCD brightness control
- *			based on the disclosed information by MEI.
- *
- *	Jul.25, 2004	Hiroshi Miura <miura@da-cha.org>
- *		- v0.4  first post version
- *		        add function to retrive SIFR

-	 *    knowledge on the IBM and Lenovo ThinkPad firmware for
-	 *    the various ThinkPad models.  The driver behaves
-	 *    differently for KEY_RESERVED: such keys have their
-	 *    hot key mask *unset* in mask_recommended, and also
-	 *    in the initial hot key mask programmed into the
-	 *    firmware at driver load time, which means the firm-
-	 *    ware may react very differently if you change them to
-	 *    something else;
-	 *
-	 * 2. You must be subscribed to the linux-thinkpad and
-	 *    ibm-acpi-devel mailing lists, and you should read the
-	 *    list archives since 2007 if you want to change the
-	 *    keymaps.  This requirement exists so that you will
-	 *    know the past history of problems with the thinkpad-
-	 *    acpi driver keymaps, and also that you will be
-	 *    listening to any bug reports;
-	 *
-	 * 3. Do not send thinkpad-acpi specific patches directly to
-	 *    for merging, *ever*.  Send them to the linux-acpi
-	 *    mailinglist for comments.  Merging is to be done only
-	 *    through acpi-test and the ACPI maintainer.
-	 *
-	 * If the above is too much to ask, don't change the keymap.
-	 * Ask the thinkpad-acpi maintainer to do it, instead.

- * FAN ACCESS MODES
- *
- * TPACPI_FAN_RD_ACPI_GFAN:
- * 	ACPI GFAN method: returns fan level
- *
- * 	see TPACPI_FAN_WR_ACPI_SFAN
- * 	EC 0x2f (HFSP) not available if GFAN exists
- *
- * TPACPI_FAN_WR_ACPI_SFAN:
- * 	ACPI SFAN method: sets fan level, 0 (stop) to 7 (max)
- *
- * 	EC 0x2f (HFSP) might be available *for reading*, but do not use
- * 	it for writing.
- *
- * TPACPI_FAN_WR_TPEC:
- * 	ThinkPad EC register 0x2f (HFSP): fan control loop mode
- * 	Supported on almost all ThinkPads
- *
- * 	Fan speed changes of any sort (including those caused by the
- * 	disengaged mode) are usually done slowly by the firmware as the
- * 	maximum ammount of fan duty cycle change per second seems to be
- * 	limited.
- *
- * 	Reading is not available if GFAN exists.
- * 	Writing is not available if SFAN exists.
- *
- * 	Bits
- *	 7	automatic mode engaged;
- *  		(default operation mode of the ThinkPad)
- * 		fan level is ignored in this mode.
- *	 6	full speed mode (takes precedence over bit 7);
- *		not available on all thinkpads.  May disable
- *		the tachometer while the fan controller ramps up
- *		the speed (which can take up to a few *minutes*).
- *		Speeds up fan to 100% duty-cycle, which is far above
- *		the standard RPM levels.  It is not impossible that
- *		it could cause hardware damage.
- *	5-3	unused in some models.  Extra bits for fan level
- *		in others, but still useless as all values above
- *		7 map to the same speed as level 7 in these models.
- *	2-0	fan level (0..7 usually)
- *			0x00 = stop
- * 			0x07 = max (set when temperatures critical)
- * 		Some ThinkPads may have other levels, see
- * 		TPACPI_FAN_WR_ACPI_FANS (X31/X40/X41)
- *
- *	FIRMWARE BUG: on some models, EC 0x2f might not be initialized at
- *	boot. Apparently the EC does not intialize it, so unless ACPI DSDT
- *	does so, its initial value is meaningless (0x07).
- *
- *	For firmware bugs, refer to:
- *	http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
- *
- * 	----
- *
- *	ThinkPad EC register 0x84 (LSB), 0x85 (MSB):
- *	Main fan tachometer reading (in RPM)
- *
- *	This register is present on all ThinkPads with a new-style EC, and
- *	it is known not to be present on the A21m/e, and T22, as there is
- *	something else in offset 0x84 according to the ACPI DSDT.  Other
- *	ThinkPads from this same time period (and earlier) probably lack the
- *	tachometer as well.
- *
- *	Unfortunately a lot of ThinkPads with new-style ECs but whose firwmare
- *	was never fixed by IBM to report the EC firmware version string
- *	probably support the tachometer (like the early X models), so
- *	detecting it is quite hard.  We need more data to know for sure.
- *
- *	FIRMWARE BUG: always read 0x84 first, otherwise incorrect readings
- *	might result.
- *
- *	FIRMWARE BUG: may go stale while the EC is switching to full speed
- *	mode.
- *
- *	For firmware bugs, refer to:
- *	http://thinkwiki.org/wiki/Embedded_Controller_Firmware#Firmware_Issues
- *
- * TPACPI_FAN_WR_ACPI_FANS:
- *	ThinkPad X31, X40, X41.  Not available in the X60.
- *
- *	FANS ACPI handle: takes three arguments: low speed, medium speed,
- *	high speed.  ACPI DSDT seems to map these three speeds to levels
- *	as follows: STOP LOW LOW MED MED HIGH HIGH HIGH HIGH
- *	(this map is stored on FAN0..FAN8 as "0,1,1,2,2,3,3,3,3")
- *
- * 	The speeds are stored on handles
- * 	(FANA:FAN9), (FANC:FANB), (FANE:FAND).
- *
- * 	There are three default speed sets, acessible as handles:
- * 	FS1L,FS1M,FS1H; FS2L,FS2M,FS2H; FS3L,FS3M,FS3H
- *
- * 	ACPI DSDT switches which set is in use depending on various
- * 	factors.
- *
- * 	TPACPI_FAN_WR_TPEC is also available and should be used to
- * 	command the fan.  The X31/X40/X41 seems to have 8 fan levels,
- * 	but the ACPI tables just mention level 7.
