2 tristate "DesignWare USB2 DRD Core Support"
3 depends on USB
4 help
5 Say Y or M here if your system has a Dual Role HighSpeed
6 USB controller based on the DesignWare HSOTG IP Core.
7
8 If you choose to build this driver as dynamically linked
9 modules, the core module will be called dwc2.ko, the
10 PCI bus interface module (if you have a PCI bus system)
11 will be called dwc2_pci.ko and the platform interface module
12 (for controllers directly connected to the CPU) will be called
13 dwc2_platform.ko.
14
15 NOTE: This driver at present only implements the Host mode
16 of the controller. The existing s3c-hsotg driver supports
17 Peripheral mode, but only for the Samsung S3C platforms.
18 There are plans to merge the s3c-hsotg driver with this
19 driver in the near future to create a dual-role driver.

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