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.

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

640 Enables monitoring of the built-in console audio output control
641 (headphone and speakers), which is operated by the mute and (in
642 some ThinkPad models) volume hotkeys.
644 If this option is enabled, ThinkPad-ACPI will export an ALSA card
645 with a single read-only mixer control, which should be used for
646 on-screen-display feedback purposes by the Desktop Environment.
648 Optionally, the driver will also allow software control (the
649 ALSA mixer will be made read-write). Please refer to the driver
650 documentation for details.
652 All IBM models have both volume and mute control. Newer Lenovo

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

700 depends on THINKPAD_ACPI
703 Allows the thinkpad_acpi driver to provide an interface to control
704 the various video output ports.
706 This feature often won't work well, depending on ThinkPad model,
707 display state, video output devices in use, whether there is a X
708 server running, phase of the moon, and the current mood of
709 Schroedinger's cat. If you can use X.org's RandR to control
710 your ThinkPad's video output ports instead of this feature,
711 don't think twice: do it and say N here to save memory and avoid
712 bad interactions with X.org.
714 NOTE: access to this feature is limited to processes with the
715 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
716 where it interacts badly with X.org.

719 be using X.org RandR instead.
721 config THINKPAD_ACPI_HOTKEY_POLL
722 bool "Support NVRAM polling for hot keys"
723 depends on THINKPAD_ACPI
726 Some thinkpad models benefit from NVRAM polling to detect a few of
727 the hot key press events. If you know your ThinkPad model does not
728 need to do NVRAM polling to support any of the hot keys you use,
729 unselecting this option will save about 1kB of memory.
731 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
732 unlikely to need NVRAM polling in their latest BIOS versions.
734 NVRAM polling can detect at most the following keys: ThinkPad/Access
735 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
736 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
738 If you are not sure, say Y here. The driver enables polling only if
739 it is strictly necessary to do so.

766 The INT33FE ACPI device has a CRS table with I2cSerialBusV2
767 resources for Fuel Gauge Controller and (in the Type-C variant)
768 FUSB302 USB Type-C Controller and PI3USB30532 USB switch.
769 This driver instantiates i2c-clients for these, so that standard
