title: Ingenic Video Processing Unit
description:
Inside the Video Processing Unit (VPU) of the recent JZ47xx SoCs from
Ingenic is a second Xburst MIPS CPU very similar to the main core.
This document describes the devicetree bindings for this auxiliary
processor.

Annotation
- Immediate include surface: `dt-bindings/clock/ingenic,jz4770-cgu.h`.
- 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.
