Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	select IIO_TRIGGERED_BUFFER
	help
	  Base module for the ChromeOS EC Sensors module.
	  Contains core functions used by other IIO CrosEC sensor
	  drivers.
	  Define common attributes and sysfs interrupt handler.

config IIO_CROS_EC_SENSORS
	tristate "ChromeOS EC Contiguous Sensors"
	depends on IIO_CROS_EC_SENSORS_CORE
	help
	  Module to handle 3d contiguous sensors like
	  Accelerometers, Gyroscope and Magnetometer that are
	  presented by the ChromeOS EC Sensor hub.
	  Creates an IIO device for each functions.

config IIO_CROS_EC_SENSORS_LID_ANGLE
	tristate "ChromeOS EC Sensor for lid angle"
	depends on IIO_CROS_EC_SENSORS_CORE
	help
	  Module to report the angle between lid and base for some
	  convertible devices.
	  This module is loaded when the EC can calculate the angle between the base
	  and the lid.

config IIO_CROS_EC_ACTIVITY
	tristate "ChromeOS EC Activity Sensors"
	depends on IIO_CROS_EC_SENSORS_CORE
	help
	  Module to handle activity events presented by the ChromeOS EC sensor hub.
	  Activities can be a proximity detector (on body/off body detection)
	  or a significant motion detector.
	  Creates an IIO device to manage all activities.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
