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.

	  This driver controls the entire USB PHY block, both the USB OTG
	  parts, as well as the 2 regular USB 2 host PHYs.

	help
	  Choose this option if you have an Allwinner SoC with
	  MIPI-DSI support. If M is selected, the module will be
	  called sun6i_mipi_dphy.

	  Enable this to support the transceiver that is part of Allwinner
	  sun9i SoCs.

	  This driver controls each individual USB 2 host PHY.

	select GENERIC_PHY
	help
	  Enable this to support the USB3.0-capable transceiver that is
	  part of Allwinner H6 SoC.

	  This driver controls each individual USB 2+3 host PHY combo.

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.
