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.

• 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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

• linux/clk.h
• linux/module.h
• sound/soc.h
• spdif.h

Detected Declarations

Annotation

• Immediate include surface: `linux/clk.h`, `linux/module.h`, `sound/soc.h`, `spdif.h`.
• Detected declarations: `function set_audio_clock_heirachy`, `function set_audio_clock_rate`, `function smdk_hw_params`, `function smdk_init`, `function smdk_exit`, `module init smdk_init`.
• Atlas domain: Driver Families / sound/soc.
• Implementation status: integration implementation candidate.

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.
