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.

	  SoundWire is a 2-Pin interface with data and clock line ratified
	  by the MIPI Alliance. SoundWire is used for transporting data
	  typically related to audio functions. SoundWire interface is
	  optimized to integrate audio devices in mobile or mobile inspired
	  systems. Say Y to enable this subsystem, N if you do not have such
	  a device

Atlas domain: Driver Families / drivers/soundwire.
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.
