The DWC2 driver should now be in good enough shape to move out of staging. I have stress tested it overnight on RPI running mass storage and Ethernet transfers in parallel, and for several days on our proprietary PCI-based platform.

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

Say N here to disable (verbose) debugging messages to be

logged for periodic transfers. This allows better debugging of

non-periodic transfers, but of course the debug logs will be

|
incomplete. Note that this also disables some debug messages
|
|
for which the transfer type cannot be deduced.
