MediaTek SoC PHY blocks (T-PHY, XS-PHY, UFS, HDMI, MIPI, DisplayPort, PCIe)
Low-level physical-layer interface blocks built into MediaTek system-on-chip designs, covering USB, SATA, PCIe, 10GbE SerDes, UFS storage, HDMI, MIPI camera and display, and DisplayPort. These are the analog front ends that sit between the SoC's digital logic and the external connectors on MediaTek-powered routers, smartphones, tablets, and Chromebooks.
recommendation
It should stay because this is an actively maintained vendor subtree serving multiple current MediaTek product lines, including the Filogic 880 networking silicon and the Dimensity 9400 smartphone platform, both still shipping in new 2025 hardware. Stable-tree backport activity as recently as 2026 confirms ongoing upstream care, and there is no generic replacement for these SoC-specific PHY blocks.

Upstream Kconfig shows this directory covers multiple current MediaTek PHY types: PCIe, 10GE SerDes, USB/SATA/PCIe T-PHY, UFS, XS-PHY, HDMI, MIPI CSI/DSI, and DP.
codex reasoning notes (technical)
Keep: this is an active vendor PHY subtree for multiple still-current MediaTek SoC product lines, not a single legacy chip driver. lore_activity on phy-mtk-tphy.c returned a 2026 lore thread URL showing continued upstream/stable traffic; web search returned current official MediaTek Filogic 880 and Dimensity 9400 product pages showing new silicon still shipping with interfaces served by these PHY drivers; Kconfig URL is canonical recall to confirm scope. No natural replacement exists beyond these vendor-specific PHY drivers.
