Marvell CCIC camera controllers for OLPC and MMP2 SoCs
Camera interface controllers built into Marvell's 88ALP01 "Cafe" companion chip (used in the first-generation OLPC XO-1 laptop, 2007) and the MMP2/Armada 610 application processors (used in the OLPC XO-1.75, which entered production in early 2012). The hardware captures video from a small sensor and feeds it to the system as a standard V4L2 webcam.
recommendation
Worth keeping but flagging as a niche legacy driver. The hardware is tied almost entirely to OLPC laptops that stopped shipping around 2012 and isn't sold new anywhere today, so real-world users are few. However, upstream is still actively fixing it: a clock-enable check landed in 6.12-stable in February 2025 and a January 2025 linux-media thread restored device registration on the MMP side, which means removing it would regress working machines that someone clearly still cares about.

January 2025 linux-media thread contains a functional fix for the MMP half of this driver set ('Bring back registration of the device'), indicating active upstream maintenance rather than removal.
- spinics.net
A December 2024 marvell camera fix ('Add check for clk_enable()') was accepted into the 6.12-stable tree in February 2025, showing current bug-fix traffic and stable relevance.

LKDDb ties CONFIG_VIDEO_CAFE_CCIC to the Marvell 88ALP01 controller and notes it is used on first-generation OLPC systems.
- linux-mmp.docs.kernel.org
Kernel-hosted Linux on Marvell MMP documentation says the XO-1.75 is MMP2-based and lists the camera as mainline-supported.
- wiki.laptop.org
OLPC documentation says XO-1.75 production ramped at the beginning of February 2012, bounding the hardware's mainstream availability.
codex reasoning notes (technical)
Real driver directory with PCI/platform entry points in local Kconfig/C files. Local shell `git log` shows substantive touches through 2024-12/2025-02, so this is not abandoned code. All cited URLs were obtained via `web.search_query`: the two spinics links came from exact patch-subject searches for recent marvell/mmp activity; the LKDDb and OLPC/kernel-doc links came from deployment/hardware searches. Evidence points to legacy OLPC-specific camera hardware that is no longer sold new, but upstream still fixes regressions, so `keep-annotate` fits better than deprecate/remove.
