3 depends on USB
4 help
5 Say Y here if your system has a Dual Role Hi-Speed USB
6 controller based on the DesignWare HSOTG IP Core.
7
8 For host mode, if you choose to build the driver as dynamically
9 linked modules, the core module will be called dwc2.ko, the PCI
10 bus interface module (if you have a PCI bus system) will be
11 called dwc2_pci.ko, and the platform interface module (for
12 controllers directly connected to the CPU) will be called
13 dwc2_platform.ko. For gadget mode, there will be a single
14 module called dwc2_gadget.ko.
15
16 NOTE: The s3c-hsotg driver is now renamed to dwc2_gadget. The
17 host and gadget drivers are still currently separate drivers.
18 There are plans to merge the dwc2_gadget driver with the dwc2
19 host driver in the near future to create a dual-role driver.

81 Say N here to disable (verbose) debugging messages to be
82 logged for periodic transfers. This allows better debugging of
83 non-periodic transfers, but of course the debug logs will be
84 incomplete. Note that this also disables some debug messages
85 for which the transfer type cannot be deduced.
