Amlogic C3 MIPI CSI-2 camera adapter
A camera-input block inside Amlogic's C3 series SoCs (C302X/C305X/C308L/C308X), which sit between the MIPI CSI-2 receiver and the image signal processor to feed pixel data from attached camera sensors. These chips are aimed at smart cameras, doorbells, and similar low-power vision devices being shipped in 2025.
recommendation
It should stay in the kernel because this is a freshly added driver (merged in May 2025 after nine review rounds) for a current Amlogic SoC family that is still being marketed in 2025, has an active maintainer entry, and is documented as a required piece of the C3 camera pipeline.

sources
- patchew.org
This driver landed through an actively reviewed 2025 C3 ISP support patch series; the MIPI adapter binding patch is part of v9, indicating current upstream bring-up rather than abandonment.
- kernel.org
Kernel documentation describes the C3 camera pipeline and explicitly includes a 'c3-mipi-adapter' sub-device, supporting that this block is part of the supported Amlogic C308L ISP pipeline.
- kernel.org
MAINTAINERS lists 'AMLOGIC MIPI ADAPTER DRIVER' as Maintained and covers drivers/media/platform/amlogic/c3/mipi-adapter/.
- amlogic.com
Amlogic's current product catalog still lists C3-family parts including C302X, C305X, C308L, and C308X, supporting that the hardware family was still marketed new in 2025/2026.
codex reasoning notes (technical)
Local inspection (`rg`, `sed`, `git -c safe.directory=... log/show`) shows this is a real platform V4L2 driver, added in one substantive upstream commit on 2025-05-09 and not an old orphan. URL evidence was obtained via web search: Patchew patch-series result for upstream activity, kernel.org C3 ISP docs for functional deployment context, kernel.org MAINTAINERS for maintained status, and Amlogic's product page for ongoing product availability. No removal discussion surfaced in the limited history/search pass; this is a new, niche SoC-internal camera block with low but current deployment, so deprecation is not indicated.
