UFS host controllers for mobile and embedded SoCs

Host controller drivers for Universal Flash Storage, the high-speed flash interface used in nearly all modern smartphones, tablets, and many embedded and automotive systems. Covers UFS host IP from Qualcomm, MediaTek, Samsung Exynos, HiSilicon, Rockchip, Renesas, Spreadtrum, TI, and AMD Versal2, spanning UFS 2.x and 3.x generations.

recommendation

It should stay because UFS is the dominant storage interface in current smartphones and embedded SoCs, with active development through early 2026, hundreds of recent commits from dozens of contributors, and ongoing enablement work for new chips like MediaTek's MT8196 and Dimensity 7020. Samsung, Qualcomm, and MediaTek continue shipping new UFS hardware in 2025 with roadmaps extending well past 2030, and there is no replacement for this role.

codex reasoning notes (technical)

Real driver directory: local shell `rg` showed module-platform/PCI driver entry points and many vendor variants (qcom, mediatek, exynos, hisi, rockchip, renesas, sprd, TI, AMD Versal2). Static metadata already shows 338 substantive commits in 5y, 77 authors, and latest touch on 2026-02-04. Lore MCP and `lei` were unavailable, so lore evidence was gathered via web `search_query`/`open` on public mail archives; those searches found active 2025 cleanup, bug-fix, and new-SoC enablement traffic, and no removal/deprecation series in the searched archive results. Deployment evidence came from web `search_query` on current vendor pages showing UFS support in still-sold 2025+ SoCs and storage products. This subsystem is current and broadly deployed, with no natural in-tree replacement for the same role.
