16 Say Y here if your system has a dual role high speed USB
17 controller based on the Mentor Graphics silicon IP. Then
18 configure options to match your silicon and the board
19 it's being used with, including the USB peripheral role,
20 or the USB host role, or both.
22 Texas Instruments parts using this IP include DaVinci 644x,
23 OMAP 243x, OMAP 343x, and TUSB 6010.
25 If you do not know what this is, please say N.
27 To compile this driver as a module, choose M here; the
28 module will be called "musb_hdrc".

51 The TUSB 6010 chip, from Texas Instruments, connects a discrete
52 HDRC core using a 16-bit parallel bus (NOR flash style) or VLYNQ
53 (a high speed serial link). It can use system-specific external

60 Dual-Role devices can support both host and peripheral roles,
61 as well as a the special "OTG Device" role which can switch
62 between both roles as needed.
64 # use USB_MUSB_HDRC_HCD not USB_MUSB_HOST to #ifdef host side support;
65 # OTG needs both roles, not just USB_MUSB_HOST.
70 Say Y here if your system supports the USB host role.
71 If it has a USB "A" (rectangular), "Mini-A" (uncommon),
72 or "Mini-AB" connector, it supports the host role.
73 (With a "Mini-AB" connector, you should enable USB OTG.)

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

89 bool "Both host and peripheral: USB OTG (On The Go) Device"
90 select USB_GADGET_MUSB_HDRC
93 The most notable feature of USB OTG is support for a
94 "Dual-Role" device, which can act as either a device
95 or a host. The initial role choice can be changed
96 later, when two dual-role devices talk to each other.
98 At this writing, the OTG support in this driver is incomplete,
99 omitting the mandatory HNP or SRP protocols. However, some
100 of the cable based role switching works. (That is, grounding
101 the ID pin switches the controller to host mode, while leaving
102 it floating leaves it in peripheral mode.)
104 Select this if your system has a Mini-AB connector, or
105 to simplify certain kinds of configuration.
107 To implement your OTG Targeted Peripherals List (TPL), enable
