help
Say Y here if your system has a dual role high speed USB
controller based on the Mentor Graphics silicon IP. Then
configure options to match your silicon and the board
it's being used with, including the USB peripheral role,
or the USB host role, or both.
Texas Instruments families using this IP include DaVinci
(35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
Analog Devices parts using this IP include Blackfin BF54x,
BF525 and BF527.
If you do not know what this is, please say N.
To compile this driver as a module, choose M here; the
module will be called "musb-hdrc".

Unfortunately, only one option can be enabled here. Ideally one
should be able to build all these drivers into one kernel to
allow using DMA on multiplatform kernels.

All data is copied between memory and FIFO by the CPU.
DMA controllers are ignored.
Do not choose this unless DMA support for your SOC or board
is unavailable (or unstable). When DMA is enabled at compile time,
you can still disable it at run time using the "use_dma=n" module
parameter.
