2 # USB Gadget support on a system involves
3 # (a) a peripheral controller, and
4 # (b) the gadget driver using it.
6 # NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
8 # - Host systems (like PCs) need CONFIG_USB (with "A" jacks).
9 # - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks).
10 # - Some systems have both kinds of controllers.
12 # With help from a special transceiver and a "Mini-AB" jack, systems with
13 # both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG).
17 bool "USB Gadget Support"
19 USB is a master/slave protocol, organized with one master
20 host (such as a PC) controlling up to 127 peripheral devices.
21 The USB hardware is asymmetric, which makes it easier to set up:
22 you can't connect a "to-the-host" connector to a peripheral.
24 U-Boot can run in the host, or in the peripheral. In both cases
25 you need a low level bus controller driver, and some software
26 talking to it. Peripheral controllers are often discrete silicon,
27 or are integrated with the CPU in a microcontroller. The more
28 familiar host side controllers have names like "EHCI", "OHCI",
29 or "UHCI", and are usually integrated into southbridges on PC
32 Enable this configuration option if you want to run U-Boot inside
33 a USB peripheral device. Configure one hardware driver for your
34 peripheral/device side bus controller, and a "gadget driver" for
35 your peripheral protocol.
39 config USB_GADGET_MANUFACTURER
40 string "Vendor name of the USB device"
41 default "Allwinner Technology" if ARCH_SUNXI
44 Vendor name of the USB device emulated, reported to the host device.
45 This is usually either the manufacturer of the device or the SoC.

48 hex "Vendor ID of the USB device"
49 default 0x1f3a if ARCH_SUNXI
52 Vendor ID of the USB device emulated, reported to the host device.

56 config USB_GADGET_PRODUCT_NUM
57 hex "Product ID of the USB device"
58 default 0x1010 if ARCH_SUNXI
61 Product ID of the USB device emulated, reported to the host device.

77 select USB_GADGET_DUALSPEED
79 The Designware USB2.0 high-speed gadget controller

81 driver to operate in Peripheral mode. This option requires
82 USB_GADGET to be enabled.

86 config USB_GADGET_DWC2_OTG_PHY_BUS_WIDTH_8
87 bool "DesignWare USB2.0 HS OTG controller 8-bit PHY bus width"

90 PHY interface width to 8 bits, rather than the default (16 bits).

102 int "Maximum VBUS Power usage (2-500 mA)"
106 Some devices need to draw power from USB when they are
107 configured, perhaps to operate circuitry or to recharge
108 batteries. This is in addition to any local power supply,
109 such as an AC adapter or batteries.
111 Enter the maximum power your device draws through USB, in
112 milliAmperes. The permitted range of values is 2 - 500 mA;
113 0 mA would be legal, but can make some hosts misbehave.
115 This value will be used except for system-specific gadget
116 drivers that have more specific information.

130 config USB_FUNCTION_SDP
131 bool "Enable USB SDP (Serial Download Protocol)"
133 Enable Serial Download Protocol (SDP) device support in U-Boot. This

140 bool "USB Ethernet Gadget"
141 default y if ARCH_SUNXI && USB_MUSB_GADGET
143 Creates an Ethernet network device through a USB peripheral
144 controller. This will create a network interface on both the device
145 (U-Boot) and the host (remote device) that can be used just like any
146 other nework interface.
147 It will bind on the peripheral USB controller, ignoring the USB hosts
148 controllers in the system.
153 prompt "USB Ethernet Gadget Model"
154 default USB_ETH_RNDIS
156 There is several models (protocols) to implement Ethernet over USB
157 devices. The main ones are Microsoft's RNDIS and USB's CDC-Ethernet
158 (also called CDC-ECM). RNDIS is obviously compatible with Windows,
159 while CDC-ECM is not. Most other operating systems support both, so
160 if inter-operability is a concern, RNDIS is to be preferred.
163 bool "CDC-ECM Protocol"
165 CDC (Communications Device Class) is the standard for Ethernet over
166 USB devices. While there's several alternatives, the most widely used
167 protocol is ECM (Ethernet Control Model). However, compatibility with
168 Windows is not that great.
171 bool "RNDIS Protocol"
173 The RNDIS (Remote Network Driver Interface Specification) is a
174 Microsoft proprietary protocol to create an Ethernet device over USB.
175 Windows obviously supports it, as well as all the major operating
176 systems, so it's the best option for compatibility.
