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.

	  Enable this to support the USB 2.0 PHY on Sunplus SP7021
	  SoC. The USB 2.0 PHY controller supports battery charger
	  and synchronous signals, various power down modes including
	  operating, partial and suspend modes, and high-speed,
	  full-speed and low-speed data transfer.

Annotation

• Atlas domain: Driver Families / drivers/phy.
• 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.
