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.

	  Say Y or M if you want to support BCM2835 built in audio.
	  This driver handles both 3.5mm and HDMI audio, by leveraging
	  the VCHIQ messaging interface between the kernel and the firmware
	  running on VideoCore.

Annotation

• Atlas domain: Driver Families / drivers/staging.
• 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.
