2 # USB Dual Role (OTG-ready) Controller Drivers
3 # for silicon based on Mentor Graphics INVENTRA designs
6 # (M)HDRC = (Multipoint) Highspeed Dual-Role Controller
8 tristate 'Inventra Highspeed Dual Role Controller (TI, ADI, ...)'
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".

33 default USB_MUSB_HOST if (USB && !USB_GADGET)
34 default USB_MUSB_GADGET if (!USB && USB_GADGET)
40 Select this when you want to use MUSB in host mode only,
41 thereby the gadget feature will be regressed.
43 config USB_MUSB_GADGET
44 bool "Gadget only mode"
47 Select this when you want to use MUSB in gadget mode only,
48 thereby the host feature will be regressed.
50 config USB_MUSB_DUAL_ROLE
52 depends on (USB && USB_GADGET)
54 This is the default mode of working of MUSB controller where
55 both host and gadget features are enabled.

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

142 Enable DMA transfers on TUSB 6010 when OMAP DMA is available.
145 bool 'Disable DMA (always use PIO)'
147 All data is copied between memory and FIFO by the CPU.
148 DMA controllers are ignored.
150 Do not choose this unless DMA support for your SOC or board
151 is unavailable (or unstable). When DMA is enabled at compile time,
152 you can still disable it at run time using the "use_dma=n" module
