Toshiba Visconti 5 (TMPV7708) SoC clock and reset controller
Provides clock and reset control for Toshiba's Visconti 5 family of automotive image-processing SoCs (TMPV7708 and siblings), which Toshiba announced in 2019 as an ADAS vision processor for cars. It is the low-level glue that lets Linux boot and run on boards built around this specialized embedded chip.
recommendation
It should stay because the Visconti 5 SoC is still sold new in 2025 through distributors like Avnet, the driver has been receiving real maintenance commits as recently as 2022–2025, and there is no alternative driver for this hardware's clock block. Deployment volumes are modest because this is a niche automotive part rather than a mass-market chip, but the platform is clearly alive upstream.

Public mailing-list patch traffic shows post-merge maintenance on this driver in 2022 ('clk: visconti: Fix memory leak in visconti_register_pll()').
- spinics.net
The 2022 visconti clock fix was reviewed and applied to clk-next, indicating normal upstream maintenance rather than abandonment.

TMPV7708 platform support continued to be added on arm64 DTS, showing the SoC family was still being enabled upstream after initial bring-up.

The Visconti platform introduction describes Visconti5/TMPV7708 as a Toshiba image-processing SoC family and ties the Linux support to real hardware boards.

Toshiba's official 2019 announcement positions Visconti 5 / TMPV770 series as an automotive ADAS processor family, i.e. specialized embedded hardware rather than obsolete PC-era silicon.

A 2026-crawled distributor page lists TMPV7708XBG as a current catalog part with factory lead time, supporting that the hardware was still sold new in 2025 even if niche.

LKDDb still tracks other Visconti TMPV7708 support in current kernels, consistent with an extant SoC family rather than a removed or orphaned platform.
codex reasoning notes (technical)
This is a real driver directory: builtin platform driver plus OF clock init in local shell inspection. Local git history shows substantive fixes/features through 2025, so not dormant. Lore-specific MCP was unavailable; I used web search to public-inbox mirrors (spinics/infradead) and found maintenance traffic but no removal discussion hits. Toshiba official news URL and Avnet URL were obtained by web search for TMPV7708/Visconti5 availability; LKDDb URL was obtained by web search for current kernel Visconti support. Niche automotive SoC implies low present-day deployment volume, but active upstream maintenance and apparent ongoing catalog sale argue to keep, with no natural replacement driver for the same clock/reset block.
