23 This driver adds support for the ACPI-WMI (Windows Management
24 Instrumentation) mapper device (PNP0C14) found on some systems.
26 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
27 ACPI firmware to userspace - this is done through various vendor
28 defined methods and data blocks in a PNP0C14 device, which are then
29 made available for userspace to call.
31 The implementation of this in Linux currently only exposes this to
32 other kernel space drivers.
34 This driver is a required dependency to build the firmware specific
35 drivers needed on many machines, including Acer and HP laptops.

651 Enables monitoring of the built-in console audio output control
652 (headphone and speakers), which is operated by the mute and (in

655 If this option is enabled, ThinkPad-ACPI will export an ALSA card
656 with a single read-only mixer control, which should be used for
657 on-screen-display feedback purposes by the Desktop Environment.
659 Optionally, the driver will also allow software control (the
660 ALSA mixer will be made read-write). Please refer to the driver
661 documentation for details.
663 All IBM models have both volume and mute control. Newer Lenovo

686 config THINKPAD_ACPI_UNSAFE_LEDS
687 bool "Allow control of important LEDs (unsafe)"
688 depends on THINKPAD_ACPI
690 Overriding LED state on ThinkPads can mask important
691 firmware alerts (like critical battery condition), or misled
692 the user into damaging the hardware (undocking or ejecting
693 the bay while buses are still active), etc.
695 LED control on the ThinkPad is write-only (with very few
696 exceptions on very ancient models), which makes it
697 impossible to know beforehand if important information will
698 be lost when one changes LED state.
700 Users that know what they are doing can enable this option
701 and the driver will allow control of every LED, including
702 the ones on the dock stations.
704 Never enable this option on a distribution kernel.

707 use, and need to control the important firmware LEDs.

710 bool "Video output control support"
711 depends on THINKPAD_ACPI
714 Allows the thinkpad_acpi driver to provide an interface to control
715 the various video output ports.
717 This feature often won't work well, depending on ThinkPad model,
718 display state, video output devices in use, whether there is a X
719 server running, phase of the moon, and the current mood of
720 Schroedinger's cat. If you can use X.org's RandR to control
721 your ThinkPad's video output ports instead of this feature,
722 don't think twice: do it and say N here to save memory and avoid
723 bad interactions with X.org.
725 NOTE: access to this feature is limited to processes with the
726 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
727 where it interacts badly with X.org.
729 If you are not sure, say Y here but do try to check if you could
730 be using X.org RandR instead.
732 config THINKPAD_ACPI_HOTKEY_POLL
733 bool "Support NVRAM polling for hot keys"
734 depends on THINKPAD_ACPI
737 Some thinkpad models benefit from NVRAM polling to detect a few of
738 the hot key press events. If you know your ThinkPad model does not
739 need to do NVRAM polling to support any of the hot keys you use,
740 unselecting this option will save about 1kB of memory.
742 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
743 unlikely to need NVRAM polling in their latest BIOS versions.
745 NVRAM polling can detect at most the following keys: ThinkPad/Access
746 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
747 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
749 If you are not sure, say Y here. The driver enables polling only if
750 it is strictly necessary to do so.

754 depends on GPIOLIB && LEDS_GPIO
756 Many Bay Trail and Cherry Trail devices come with a camera attached
757 to Intel's Image Signal Processor. Linux currently does not have a
758 driver for these, so they do not work as a camera. Some of these
759 camera's have a LED which is controlled through a GPIO.
761 Some of these devices have a firmware issue where the LED gets turned
762 on at boot. This driver will turn the LED off at boot and also allows
763 controlling the LED (repurposing it) through the sysfs LED interface.
765 Which GPIO is attached to the LED is usually not described in the
766 ACPI tables, so this driver contains per-system info about the GPIO
767 inside the driver, this means that this driver only works on systems
768 the driver knows about.

794 some Intel Cherry Trail devices.
796 There are two kinds of INT33FE ACPI device possible: for hardware
797 with USB Type-C and Micro-B connectors. This driver supports both.
799 The INT33FE ACPI device has a CRS table with I2cSerialBusV2
800 resources for Fuel Gauge Controller and (in the Type-C variant)
801 FUSB302 USB Type-C Controller and PI3USB30532 USB switch.
802 This driver instantiates i2c-clients for these, so that standard
803 i2c drivers for these chips can bind to the them.
