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

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

88 # side support ... OTG needs both roles

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

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