Nuvoton MA35D1 USB 2.0 PHY

The on-chip USB 2.0 high-speed PHY found in Nuvoton's MA35D1 Arm Cortex-A35 microprocessor family, a current generation of embedded SoCs aimed at industrial and edge-IIoT applications such as gateways and system-on-modules.

recommendation

It should stay because the driver is brand new, added in August 2024 for a current Nuvoton SoC family that is still being actively marketed and shipped in new edge/industrial IoT system-on-modules as of June 2025. There is no alternative driver for this hardware, and no upstream signals suggest deprecation.

sources

  1. lore.kernel.org

    Upstream evidence for this directory is a 2024 patch series adding the Nuvoton MA35 USB 2.0 PHY driver; no older history exists for the directory.

  2. nuvoton.com

    Nuvoton still markets the MA35D1 family as a current product line with USB 2.0 HS and industrial/edge-IIoT positioning.

  3. nuvoton.com

    Nuvoton announced an MA35D1-based EMAC SoM on June 26, 2025 with availability stated as 'Now. Sold Worldwide.', showing new-product deployment in 2025.

codex reasoning notes (technical)

Real driver directory: contains Kconfig/Makefile plus a platform PHY driver with module_platform_driver for compatible 'nuvoton,ma35d1-usb2-phy'. The lore URL was obtained from local `git log --follow --stat -- drivers/phy/nuvoton` via exec_command; it shows the directory was added in August 2024 and there is no long decay history or visible removal signal. The two Nuvoton URLs were obtained by web search and opened with the web tool; they show MA35D1 remains an actively marketed embedded SoC family and was still entering new SoM designs in 2025. This is niche embedded hardware, so deployments are low rather than mass-market, but the driver is too new and current for deprecation; there is no natural replacement beyond this SoC-specific PHY driver.
