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 parts using this IP include DaVinci 644x,
25 OMAP 243x, OMAP 343x, 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".

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

86 # side support ... OTG needs both roles
87 config USB_MUSB_PERIPHERAL
89 bool "USB Peripheral (gadget stack)"
90 select USB_GADGET_MUSB_HDRC
92 Say Y here if your system supports the USB peripheral role.
93 If it has a USB "B" (squarish), "Mini-B", or "Mini-AB"
94 connector, it supports the peripheral role.
95 (With a "Mini-AB" connector, you should enable USB OTG.)

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

189 This enables the old musb procfs entry. Ideally this would move to a userland application
