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.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/ptp_clock_kernel.h

Detected Declarations

• struct nxp_c45_macsec
• struct nxp_c45_phy
• function nxp_c45_macsec_config_init
• function nxp_c45_macsec_probe
• function nxp_c45_macsec_remove

Annotation

• Immediate include surface: `linux/ptp_clock_kernel.h`.
• Detected declarations: `struct nxp_c45_macsec`, `struct nxp_c45_phy`, `function nxp_c45_macsec_config_init`, `function nxp_c45_macsec_probe`, `function nxp_c45_macsec_remove`.
• Atlas domain: Driver Families / drivers/net.
• Implementation status: source implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
