Siano SMS1xxx mobile digital TV SDIO receivers
Support for Siano SMS1xxx mobile digital TV tuner chips that connect over the SDIO bus, used in late-2000s and early-2010s handsets, tablets, and accessory dongles to receive mobile broadcast TV standards such as DVB-H, ISDB-T, and ATSC-M/H. The hardware was aimed at a mobile-broadcast-TV market that largely failed to materialize at scale.
recommendation
A candidate for future removal because the Siano SMS1xxx mobile-TV chips it supports belong to a handheld broadcast-TV ecosystem that peaked around 2010 and never gained lasting traction. Upstream activity is limited to janitorial cleanups (the most recent notable change is a 2024 module-init refactor), no new hardware is shipping in this category, and real-world deployments today appear minimal. It is not actively broken, so deprecation rather than immediate removal is appropriate.

Recent upstream activity on this driver is a 2024 module-init cleanup, indicating maintenance is minimal and not feature-driven.

The broader Siano support is for mobile digital TV receivers, a product category tied to older handset/accessory ecosystems rather than current mainstream deployments.

Siano's own current company page describes the business around mobile broadcast DTV solutions for handheld, tablet, automotive, and transportation devices, consistent with legacy/niche deployment rather than new mainstream hardware.

Public product/news coverage for Siano mobile-TV chips is from the early 2010 era, supporting the conclusion that broad commercial availability is historical rather than current.
codex reasoning notes (technical)
Local shell inspection showed MODULE_DESCRIPTION='Siano SMS1xxx SDIO driver', identifying the chipset family. lore_file_timeline on drivers/media/mmc/siano/smssdio.c returned only sparse history and no removal-series signal; the notable recent lore URL above was obtained via MCP lore_file_timeline. LKDDb pages were obtained by web search and confirm this is a narrow Siano SMS1xxx SDIO mobile-DTV driver still present in Kconfig, but that says little about active use. The Siano company page and old industry coverage were obtained by web search; together they indicate a legacy mobile-broadcast-TV market that peaked long ago. With no natural successor for the same hardware but very weak maintenance and low likelihood of new deployments, deprecate is the best fit.
