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.

Annotated Snippet

config USB_CDNS2_UDC
	tristate "Cadence USBHS Device Controller"
	depends on USB_PCI && ACPI && HAS_DMA
	help
	  Cadence USBHS Device controller is a PCI based USB peripheral
	  controller which supports both full and high speed USB 2.0
	  data transfers.

	  Say "y" to link the driver statically, or "m" to build a
	  dynamically linked module called "cdns2-udc-pci.ko" and to
	  force all gadget drivers to also be dynamically linked.

Annotation

Atlas domain: Driver Families / drivers/usb.
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.
