Toshiba Visconti TMPV7700/TMPV7708 SoC pin controller

Pin multiplexing and GPIO configuration support for Toshiba's Visconti 5 family of automotive system-on-chip processors (TMPV7700 series, including the TMPV7708), which Toshiba markets for advanced driver-assistance systems in cars. The chips are still orderable through distributors like Avnet in 2025.

recommendation

Worth keeping but documenting its niche, because the Visconti SoC family is genuinely active hardware that Toshiba still sells for automotive ADAS use, and there was DT/pinctrl discussion as recently as October 2025. However, the driver itself has seen almost no churn since its 2020 introduction, so it's a quiet, low-deployment corner of the kernel that deserves a note about its narrow automotive scope rather than removal.

  1. lore.kernel.org

    Latest lore hit for pinctrl-tmpv7700.c was September 9, 2020, in the initial 'Add Toshiba Visconti SoCs pinctrl support' series.

  2. lore.kernel.org

    Latest lore hit for pinctrl-common.c was December 17, 2020, during initial Visconti GPIO support bring-up, with no newer driver-file activity seen in lore timelines.

  3. cateee.net

    CONFIG_PINCTRL_VISCONTI is still present in current upstream kernels and matches both tmpv7700-pinctrl and toshiba,tmpv7708-pinctrl.

  4. toshiba.semicon-storage.com

    Toshiba identifies Visconti 5 as the TMPV770 series and positions it for automotive driver-assistance systems.

  5. avnet.com

    TMPV7708XBG(ES) had a live distributor listing with factory lead time, consistent with still-orderable new hardware in 2025-era channels.

  6. spinics.net

    TMPV7708 platform maintenance was still visible in October 2025 through DT/pinctrl-related discussion, suggesting the SoC is not fully abandoned upstream.

codex reasoning notes (technical)

Lore evidence came from mcp__lore_http__.lore_file_timeline on drivers/pinctrl/visconti/pinctrl-tmpv7700.c and pinctrl-common.c; both timelines stop at 2020 bring-up, and no removal talk appeared in that history. LKDDb, Toshiba, Avnet, and the 2025 TMPV7708 DT thread URLs were obtained via web search. The driver is extremely quiet and clearly niche, but the hardware family still appears orderable and adjacent platform support still receives occasional upstream maintenance, so deprecation/removal is too aggressive; keep it, but annotate it as low-traffic niche automotive SoC support.
