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".

80 The TUSB 6010 chip, from Texas Instruments, connects a discrete
81 HDRC core using a 16-bit parallel bus (NOR flash style) or VLYNQ
82 (a high speed serial link). It can use system-specific external
87 depends on USB_MUSB_HDRC
89 Dual-Role devices can support both host and peripheral roles,
90 as well as a the special "OTG Device" role which can switch
91 between both roles as needed.
93 # use USB_MUSB_HDRC_HCD not USB_MUSB_HOST to #ifdef host side support;
94 # OTG needs both roles, not just USB_MUSB_HOST.
99 Say Y here if your system supports the USB host role.
100 If it has a USB "A" (rectangular), "Mini-A" (uncommon),
101 or "Mini-AB" connector, it supports the host role.
102 (With a "Mini-AB" connector, you should enable USB OTG.)
104 # use USB_GADGET_MUSB_HDRC not USB_MUSB_PERIPHERAL to #ifdef peripheral
105 # side support ... OTG needs both roles

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

118 bool "Both host and peripheral: USB OTG (On The Go) Device"
119 select USB_GADGET_MUSB_HDRC
122 The most notable feature of USB OTG is support for a
123 "Dual-Role" device, which can act as either a device
124 or a host. The initial role choice can be changed
125 later, when two dual-role devices talk to each other.
127 At this writing, the OTG support in this driver is incomplete,
128 omitting the mandatory HNP or SRP protocols. However, some
129 of the cable based role switching works. (That is, grounding
130 the ID pin switches the controller to host mode, while leaving
131 it floating leaves it in peripheral mode.)
133 Select this if your system has a Mini-AB connector, or
134 to simplify certain kinds of configuration.
136 To implement your OTG Targeted Peripherals List (TPL), enable
