8 tristate 'Inventra Highspeed Dual Role Controller (TI, ADI, ...)'
9 depends on (USB || USB_GADGET)
11 Say Y here if your system has a dual role high speed USB
12 controller based on the Mentor Graphics silicon IP. Then
13 configure options to match your silicon and the board
14 it's being used with, including the USB peripheral role,
15 or the USB host role, or both.
17 Texas Instruments families using this IP include DaVinci
18 (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
20 Analog Devices parts using this IP include Blackfin BF54x,
23 If you do not know what this is, please say N.
25 To compile this driver as a module, choose M here; the
26 module will be called "musb-hdrc".

121 allow using DMA on multiplatform kernels.

154 bool 'Disable DMA (always use PIO)'
156 All data is copied between memory and FIFO by the CPU.
157 DMA controllers are ignored.
159 Do not choose this unless DMA support for your SOC or board
160 is unavailable (or unstable). When DMA is enabled at compile time,
161 you can still disable it at run time using the "use_dma=n" module
