20 Say Y here if your system has a dual role high speed USB
21 controller based on the Mentor Graphics silicon IP. Then
22 configure options to match your silicon and the board
23 it's being used with, including the USB peripheral role,
24 or the USB host role, or both.
26 Texas Instruments familiies using this IP include DaVinci
27 (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
29 Analog Devices parts using this IP include Blackfin BF54x,
32 If you do not know what this is, please say N.
34 To compile this driver as a module, choose M here; the
35 module will be called "musb_hdrc".

64 The TUSB 6010 chip, from Texas Instruments, connects a discrete
65 HDRC core using a 16-bit parallel bus (NOR flash style) or VLYNQ
66 (a high speed serial link). It can use system-specific external
71 depends on USB_MUSB_HDRC
73 Dual-Role devices can support both host and peripheral roles,
74 as well as a the special "OTG Device" role which can switch
75 between both roles as needed.
77 # use USB_MUSB_HDRC_HCD not USB_MUSB_HOST to #ifdef host side support;
78 # OTG needs both roles, not just USB_MUSB_HOST.
83 Say Y here if your system supports the USB host role.
84 If it has a USB "A" (rectangular), "Mini-A" (uncommon),
85 or "Mini-AB" connector, it supports the host role.
86 (With a "Mini-AB" connector, you should enable USB OTG.)

95 Say Y here if your system supports the USB peripheral role.
96 If it has a USB "B" (squarish), "Mini-B", or "Mini-AB"
97 connector, it supports the peripheral role.
98 (With a "Mini-AB" connector, you should enable USB OTG.)

102 bool "Both host and peripheral: USB OTG (On The Go) Device"
103 select USB_GADGET_MUSB_HDRC
106 The most notable feature of USB OTG is support for a
107 "Dual-Role" device, which can act as either a device
108 or a host. The initial role choice can be changed
109 later, when two dual-role devices talk to each other.
111 At this writing, the OTG support in this driver is incomplete,
112 omitting the mandatory HNP or SRP protocols. However, some
113 of the cable based role switching works. (That is, grounding
114 the ID pin switches the controller to host mode, while leaving
115 it floating leaves it in peripheral mode.)
117 Select this if your system has a Mini-AB connector, or
118 to simplify certain kinds of configuration.

121 USB_OTG_WHITELIST and update "drivers/usb/core/otg_whitelist.h"
