Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  Support for Intersil/Techwell TW686x-based frame grabber cards.

	  Currently supported chips:
	  - TW6864 (4 video channels),
	  - TW6865 (4 video channels, not tested, second generation chip),
	  - TW6868 (8 video channels but only 4 first channels using
	    built-in video decoder are supported, not tested),
	  - TW6869 (8 video channels, second generation chip).

	  To compile this driver as a module, choose M here: the module
	  will be named tw686x.

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.
