MediaTek DVFSRC and EMI interconnect provider for MT8183/MT8195/MT8196 SoCs

A small kernel component that arbitrates on-chip memory and bus bandwidth between CPU, GPU, and other blocks on MediaTek's recent Kompanio-class application processors, including the MT8183, MT8195, and newer MT8196 used in 2024–2025 Chromebooks and ARM laptops, so DRAM throughput and power scale correctly under load.

recommendation

It should stay because the code is new (added in mid-2024), still actively growing, and tied to MediaTek silicon that is shipping in current Chromebook Plus and similar devices. Support for the latest MT8196 SoC landed as recently as December 2025, and there is no sign of removal discussion upstream, so this is firmly in the enablement phase rather than the retirement phase.

codex reasoning notes (technical)

Real driver directory: platform interconnect providers for mediatek,mt8183-emi / mt8195-emi / mt8196-emi. Local shell inspection of Kconfig and .c files confirmed driver entrypoints and supported compatibles. Local shell `git log` showed 6 substantive commits since introduction, with latest fixes and MT8196 support on 2025-12-21; kernel.org commit URLs were then formed via canonical recall from those hashes. Web search found no lore.kernel.org removal/deprecation hits for this directory, so there is no evidence of active upstream removal talk. The MT8196 platform doc URL was obtained by web search; the MediaTek 2025 Kompanio Ultra press URL was obtained by web search. Taken together, this is recently introduced, still expanding, and tied to currently shipping MediaTek compute silicon, so removal/deprecation is not indicated.
