TI DaVinci DA850, OMAP-L138, and AM18xx SoC clock controllers

Provides clock-tree control for Texas Instruments' DaVinci-generation ARM9 and C6000 DSP system-on-chips, including the DA850, OMAP-L138, AM1808/AM1810, and TMS320C6748. These low-power parts launched around 2009 and remain in production for industrial automation, motor control, medical, and audio-processing designs that need a long-lived embedded Linux platform.

recommendation

It should stay in the kernel because Texas Instruments still actively sells the DA850-family chips this code supports (OMAP-L138, AM1808, TMS320C6748 were all listed as ACTIVE in 2025), and the driver is still being maintained — a fix was backported to the stable tree as recently as August 2025. Deployments are niche, mostly in long-lived industrial and embedded designs, but there is no sign of upstream wanting it gone.

sources

  1. lore.kernel.org

    The driver saw upstream-worthy maintenance recently; a davinci clock fix was backported to stable in August 2025.

  2. ti.com

    OMAP-L138, one of the SoCs explicitly covered by this driver family, was listed by TI as ACTIVE and orderable.

  3. ti.com

    AM1808, another DA850-family part covered by this driver family, was listed by TI as ACTIVE and supports Linux/RTOS use cases.

  4. ti.com

    TMS320C6748, closely related DA850-family silicon, was listed by TI as ACTIVE, indicating the platform family is not fully obsolete in new industrial/embedded designs.

codex reasoning notes (technical)

Real driver, not a helper-only directory: local `rg`/`sed` inspection shows platform clock driver code and DT compatibles for `ti,da850-*`; file headers name 'TI DA850/OMAP-L138/AM18XX'. MCP `lore_file_timeline` on `drivers/clk/davinci/psc.c` showed activity through 2025-08-28 and exposed the cited stable backport URL, with no removal/deprecation evidence surfaced. TI product URLs were obtained via web search results and show the DA850-family parts still marked ACTIVE in 2025. Conclusion: niche legacy-industrial deployments remain, but there is still shipping hardware and ongoing maintenance, so keep rather than deprecate.
