STMicroelectronics STiH4xx HDMI CEC controller

The HDMI Consumer Electronics Control block found inside STMicroelectronics' STiH4xx family of set-top-box and digital-TV system-on-chips (STiH407, STiH410, STiH418), which lets a TV remote drive a connected box over the HDMI cable. These chips powered cable, satellite, and IPTV boxes and a handful of developer boards in the mid-2010s, and ST has since wound the product line down.

recommendation

A candidate for future removal because the STiH4xx set-top-box SoCs it supports (STiH407, STiH410, STiH418) are an old, niche platform whose closest sibling, the STiH412, is already marked obsolete by ST. Upstream activity since the mid-2010s has been limited to mechanical cleanups rather than real maintenance, and the hardware mostly survives in legacy boxes and a few development boards like the 96Boards B2260. There is no current replacement driver and a small installed base may still exist, so outright removal would be premature, but it is reasonable to flag it for eventual retirement.

sources

lore.kernel.org
Recent upstream touch was a treewide API churn change ('Switch back to struct platform_driver::remove()'), not evidence of active feature work or broad bug-fix traffic for this driver.
kernel.org
Kernel STi ARM overview names STiH407, STiH410 and STiH418 as the supported STi Cortex-A9 multimedia/set-top-box SoC families tied to this platform.
96boards.org
A documented public board using this SoC family is the B2260 development board based on Cannes2-STiH410, indicating the driver's hardware exists mainly as older STiH410-era dev/set-top-box hardware.
st.com
ST marks the closely related STiH412 digital set-top-box SoC as 'Obsolete / Out of Production', supporting the conclusion that new STiH4xx-family deployments are no longer a current market.

codex reasoning notes (technical)

Shell inspection of local source showed this is the STIH4xx HDMI CEC platform driver ('stih-cec', DT compatible 'st,stih-cec') and DT wiring in legacy STiH410 SoC files. Upstream activity came from lore_file_timeline on the source file: touches exist through 2024, but they are sparse and mostly mechanical/cleanup-oriented rather than active maintenance. Web search found kernel.org STi overview pages and 96Boards B2260 docs, showing the hardware is an older STiH4xx/Cannes-era set-top-box/dev-board platform. Web search also found ST's STiH412 page marked obsolete; this is an inference about the broader STiH4xx market, not a direct STiH410/STiH418 EOL notice. Given low but nonzero legacy deployments and lack of a same-hardware replacement driver, deprecate is stronger than keep-annotate, but there is not enough evidence for immediate removal.
