3 depends on USB
4 depends on VIRT_TO_BUS
5 help
6 Say Y or M here if your system has a Dual Role HighSpeed
7 USB controller based on the DesignWare HSOTG IP Core.
8
9 If you choose to build this driver as dynamically linked
10 modules, the core module will be called dwc2.ko, the
11 PCI bus interface module (if you have a PCI bus system)
12 will be called dwc2_pci.ko and the platform interface module
13 (for controllers directly connected to the CPU) will be called
14 dwc2_platform.ko.
15
16 NOTE: This driver at present only implements the Host mode
17 of the controller. The existing s3c-hsotg driver supports
18 Peripheral mode, but only for the Samsung S3C platforms.
19 There are plans to merge the s3c-hsotg driver with this
20 driver in the near future to create a dual-role driver.

47 default y
48 help
49 Say N here to disable (verbose) debugging messages to be
50 logged for periodic transfers. This allows better debugging of
51 non-periodic transfers, but of course the debug logs will be
52 incomplete. Note that this also disables some debug messages
53 for which the transfer type cannot be deduced.
