description: |
The Raspberry Pi PiSP Camera Front End is a module in Raspberrypi 5's RP1 I/O
controller, that contains:
- MIPI D-PHY
- MIPI CSI-2 receiver
- Simple image processor (called PiSP Front End, or FE)
The FE documentation is available at:
https://datasheets.raspberrypi.com/camera/raspberry-pi-image-signal-processor-specification.pdf
The PHY and CSI-2 receiver part have no public documentation.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
