18 Say Y here if your system has a dual role high speed USB
19 controller based on the Mentor Graphics silicon IP. Then
20 configure options to match your silicon and the board
21 it's being used with, including the USB peripheral role,
22 or the USB host role, or both.
24 Texas Instruments familiies using this IP include DaVinci
25 (35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
27 Analog Devices parts using this IP include Blackfin BF54x,
30 If you do not know what this is, please say N.
32 To compile this driver as a module, choose M here; the
33 module will be called "musb_hdrc".

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

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

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

100 bool "Both host and peripheral: USB OTG (On The Go) Device"
101 select USB_GADGET_MUSB_HDRC
104 The most notable feature of USB OTG is support for a
105 "Dual-Role" device, which can act as either a device
106 or a host. The initial role choice can be changed
107 later, when two dual-role devices talk to each other.
109 At this writing, the OTG support in this driver is incomplete,
110 omitting the mandatory HNP or SRP protocols. However, some
111 of the cable based role switching works. (That is, grounding
112 the ID pin switches the controller to host mode, while leaving
113 it floating leaves it in peripheral mode.)
115 Select this if your system has a Mini-AB connector, or
116 to simplify certain kinds of configuration.
118 To implement your OTG Targeted Peripherals List (TPL), enable
119 USB_OTG_WHITELIST and update "drivers/usb/core/otg_whitelist.h"
