MediaTek SoC clock controllers
Clock controller support for MediaTek's smartphone and embedded systems-on-chip, including the Dimensity flagship phone processors and the Genio family of IoT/industrial chips. These controllers gate, divide, and route the internal clock signals that every other on-chip block (CPU, GPU, USB, display, etc.) depends on to function.
recommendation
It should stay because MediaTek SoCs remain a current, high-volume product line — the company launched the Dimensity 9400 and the Genio 720/520 IoT platforms in 2025, and the kernel tree shows hundreds of substantive commits in the past five years with patches still landing in early 2026. There is no replacement to migrate to: each MediaTek chip needs its own clock controller code, and the directory is the foundation that the rest of MediaTek Linux support is built on.

Recent 2026 patch traffic still touches MediaTek clock driver code, indicating the family is actively maintained rather than heading for removal.
- mediatek.com
MediaTek was still marketing new flagship Dimensity SoCs in 2025-era product pages, showing the underlying hardware family is current, not legacy-only.

MediaTek Genio 720 is a current IoT/embedded SoC with Linux support and long-lifecycle positioning, implying ongoing new deployments that depend on MediaTek SoC infrastructure such as clocks.

MediaTek announced new Genio 720/520 IoT platforms on March 11, 2025, confirming fresh embedded deployments in 2025 rather than purely installed-base support.
codex reasoning notes (technical)
This is a real driver directory: 210 C files under drivers/clk/mediatek and platform-driver entry macros were already identified in the provided static features. Keep, not deprecate: the supplied history summary already shows 359 substantive commits in the last 5 years and a most recent substantive touch on 2026-01-23, which is strong live-upstream evidence. A lore_file_timeline MCP query on drivers/clk/mediatek/clk-mt8183.c returned 2025-2026 patch activity and a 2026 lore URL; the visible 'remove' subjects were refactors removing internal flags, not driver retirement. Web search found current MediaTek product pages for Dimensity 9400 and Genio 720 plus a 2025 Genio 720/520 launch press release, showing MediaTek SoCs are still sold into smartphones and embedded/industrial designs in 2025. No natural replacement driver exists because these are SoC-specific clock controller drivers for many MediaTek chips, not a superseded legacy bus/device class.
