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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/io.h
• linux/types.h

Detected Declarations

• struct dphy_data

Annotated Snippet

struct dphy_data {
	struct device *dev;

	void __iomem *base;

	u32 dphy_rate;
	u32 max_lanes;
	u32 active_lanes;
};

void dphy_probe(struct dphy_data *dphy);
void dphy_start(struct dphy_data *dphy);
void dphy_stop(struct dphy_data *dphy);

Annotation

• Immediate include surface: `linux/io.h`, `linux/types.h`.
• Detected declarations: `struct dphy_data`.
• Atlas domain: Driver Families / drivers/media.
• Implementation status: source 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.
