Annotated Snippet
What: /sys/bus/iio/devices/iio:deviceX/calibrate
Date: July 2015
KernelVersion: 4.7
Contact: linux-iio@vger.kernel.org
Description:
Writing '1' either perform a FOC (Fast Online Calibration) or
enter calibration mode.
Writing '0` exits calibration mode. It is a NOP for FOC enabled
sensors.
The corresponding calibration offsets can be read from `*_calibbias`
entries.
What: /sys/bus/iio/devices/iio:deviceX/id
Date: September 2017
KernelVersion: 4.14
Contact: linux-iio@vger.kernel.org
Description:
This attribute is exposed by the CrOS EC sensors driver and
represents the sensor ID as exposed by the EC. This ID is used
by the Android sensor service hardware abstraction layer (sensor
HAL) through the Android container on ChromeOS.Annotation

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.
