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.

	depends on B53 && SPI
	help
	  Select to enable support for registering switches configured through SPI.

config B53_MDIO_DRIVER
	tristate "B53 MDIO connected switch driver"
	depends on B53
	help
	  Select to enable support for registering switches configured through MDIO.

config B53_MMAP_DRIVER

	  Select to enable support for SerDes on e.g: Northstar Plus SoCs.

Annotation

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