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.

Dependency Surface

• rc-core-priv.h
• linux/module.h

Detected Declarations

• enum rc5_state
• function ir_rc5_decode
• function ir_rc5_encode
• function ir_rc5_decode_init
• function ir_rc5_decode_exit
• module init ir_rc5_decode_init

Annotation

• Immediate include surface: `rc-core-priv.h`, `linux/module.h`.
• Detected declarations: `enum rc5_state`, `function ir_rc5_decode`, `function ir_rc5_encode`, `function ir_rc5_decode_init`, `function ir_rc5_decode_exit`, `module init ir_rc5_decode_init`.
• Atlas domain: Driver Families / drivers/media.
• 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.
