Industrial I/O (IIO) subsystem root

The top-level directory for Linux's Industrial I/O framework, which provides the common infrastructure that hundreds of individual sensor drivers (accelerometers, gyroscopes, ADCs, light sensors, magnetometers, and similar analog/data-acquisition devices) plug into. It is the umbrella, not a driver for any one chip.

recommendation

This is not actually a single driver; it is the parent directory for the entire Industrial I/O subsystem and all of its child sensor drivers. Any keep-or-remove judgement has to be made on the individual drivers underneath it, not on the directory itself.

codex reasoning notes (technical)

Not a driver directory: subsystem-level Industrial I/O core/parent directory containing framework and multiple child drivers, not one hardware-bound driver.
