      Video port for DPI RGB output.
      ltdc has one video port with up to 2 endpoints:
      - for external dpi rgb panel or bridge, using gpios.
      - for internal dpi input of the MIPI DSI host controller.
      Note: These 2 endpoints cannot be activated simultaneously.

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.
