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 here to include Cirrus Logic HD-audio codec support.
This will enable both CS420x and CS421x HD-audio codec drivers
as default, but you can enable/disable each codec driver
individually, too (only when CONFIG_EXPERT is set).

Annotation
- Atlas domain: Driver Families / sound/hda.
- 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.
