title: MIPI DSI to eDP Video Format Converter
maintainers:
- Nicolas Boichat <drinkcat@chromium.org>
description: |
The PS8640 is a low power MIPI-to-eDP video format converter supporting
mobile devices with embedded panel resolutions up to 2048 x 1536. The
device accepts a single channel of MIPI DSI v1.1, with up to four lanes
plus clock, at a transmission rate up to 1.5Gbit/sec per lane. The
device outputs eDP v1.4, one or two lanes, at a link rate of up to
3.24Gbit/sec per lane.

Annotation
- Immediate include surface: `dt-bindings/gpio/gpio.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.
