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_CDNS_SUPPORT
tristate "Cadence USB Support"
depends on USB_SUPPORT && (USB || USB_GADGET) && HAS_DMA
select USB_XHCI_PLATFORM if USB_XHCI_HCD
select USB_ROLE_SWITCH
help
Say Y here if your system has a Cadence USBSS or USBSSP
dual-role controller.
It supports: dual-role switch, Host-only, and Peripheral-only.
config USB_CDNS_HOST
bool
if USB_CDNS_SUPPORT
config USB_CDNS3
tristate "Cadence USB3 Dual-Role Controller"
depends on USB_CDNS_SUPPORT
help
Say Y here if your system has a Cadence USB3 dual-role controller.
It supports: dual-role switch, Host-only, and Peripheral-only.
If you choose to build this driver is a dynamically linked
as module, the module will be called cdns3.ko.
endif
if USB_CDNS3
config USB_CDNS3_GADGET
bool "Cadence USB3 device controller"
depends on USB_GADGET=y || USB_GADGET=USB_CDNS3
help
Say Y here to enable device controller functionality of the
Cadence USBSS-DEV driver.
This controller supports FF, HS and SS mode. It doesn't support
LS and SSP mode.
config USB_CDNS3_HOST
bool "Cadence USB3 host controller"
depends on USB=y || USB=USB_CDNS3
select USB_CDNS_HOST
help
Say Y here to enable host controller functionality of the
Cadence driver.
Host controller is compliant with XHCI so it will use
standard XHCI driver.
config USB_CDNS3_PCI_WRAP
tristate "Cadence USB3 support on PCIe-based platforms"
depends on USB_PCI && ACPI
default USB_CDNS3
help
If you're using the USBSS Core IP with a PCIe, please say
'Y' or 'M' here.
If you choose to build this driver as module it will
be dynamically linked and module will be called cdns3-pci.ko
config USB_CDNS3_TI
tristate "Cadence USB3 support on TI platforms"
depends on ARCH_K3 || COMPILE_TEST
default USB_CDNS3
help
Say 'Y' or 'M' here if you are building for Texas Instruments
platforms that contain Cadence USB3 controller core.
e.g. J721e.
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.
