Analog Devices ADIS16203 Programmable Inclinometer
A high-precision SPI-attached dual-axis inclinometer from Analog Devices' iSensor family, used in industrial tilt-sensing applications such as platform leveling, structural monitoring, and machine alignment. The part has been on the market since the late 2000s and is still listed in production by Analog Devices today.
recommendation
Worth keeping but documenting its niche because the ADIS16203 is a specialized industrial inclinometer that Analog Devices still sells new in 2025, and the kernel driver has seen real maintenance as recently as 2022 and routine subsystem-wide cleanups in 2025. It lives in staging and serves a small audience, so a clear note about its industrial-only role would help, but there is no sign anyone wants it removed.

sources
- analog.com
Analog Devices lists ADIS16203 as PRODUCTION with pricing and Sample & Buy availability, so the hardware was still sold new in 2025.
- analog.com
Analog Devices still documents an ADIS16203 evaluation board and Linux reference design, indicating ongoing niche/industrial deployment rather than complete disappearance.
- lore.kernel.org
There was real upstream maintenance for this specific driver in late 2022, reviewed and merged through the IIO subsystem.
- patch.msgid.link
The file was touched again in 2025 as part of active subsystem-wide maintenance, with no evidence of removal planning in the observed recent history.
codex reasoning notes (technical)
Local path inspection via shell showed this directory contains a real SPI IIO driver, adis16203.c, for the Analog Devices ADIS16203. Recent activity was checked with shell git log (safe.directory override); it showed substantive 2022 maintenance and 2025 subsystem churn, and no removal/deprecation series was visible in the available history. Public hardware status came from web search results on analog.com: the product page says PRODUCTION and the eval-board page still exists with Linux reference material. Because the part still appears orderable but is a specialized inclinometer in staging with only occasional upkeep, current deployments are best classified as low and the driver should be kept but annotated rather than deprecated or removed.
