# USB Gadget support on a system involves
#    (a) a peripheral controller, and
#    (b) the gadget driver using it.
#
# NOTE:  Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
#
#  - Host systems (like PCs) need CONFIG_USB (with "A" jacks).
#  - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks).
#  - Some systems have both kinds of controllers.
#
# With help from a special transceiver and a "Mini-AB" jack, systems with
# both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG).

menuconfig USB_GADGET
	bool "USB Gadget Support"
	help
	   USB is a master/slave protocol, organized with one master
	   host (such as a PC) controlling up to 127 peripheral devices.
	   The USB hardware is asymmetric, which makes it easier to set up:
	   you can't connect a "to-the-host" connector to a peripheral.

	   U-Boot can run in the host, or in the peripheral.  In both cases
	   you need a low level bus controller driver, and some software
	   talking to it.  Peripheral controllers are often discrete silicon,
	   or are integrated with the CPU in a microcontroller.  The more
	   familiar host side controllers have names like "EHCI", "OHCI",
	   or "UHCI", and are usually integrated into southbridges on PC
	   motherboards.

	   Enable this configuration option if you want to run U-Boot inside
	   a USB peripheral device.  Configure one hardware driver for your
	   peripheral/device side bus controller, and a "gadget driver" for
	   your peripheral protocol.

	  The Designware USB2.0 high-speed gadget controller
	  integrated into many SoCs. Select this option if you want the
	  driver to operate in Peripheral mode. This option requires
	  USB_GADGET to be enabled.

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

config USB_GADGET_VBUS_DRAW
	int "Maximum VBUS Power usage (2-500 mA)"
	range 2 500
	default 2
	help
	   Some devices need to draw power from USB when they are
	   configured, perhaps to operate circuitry or to recharge
	   batteries.  This is in addition to any local power supply,
	   such as an AC adapter or batteries.

	   Enter the maximum power your device draws through USB, in
	   milliAmperes.  The permitted range of values is 2 - 500 mA;
	   0 mA would be legal, but can make some hosts misbehave.

	   This value will be used except for system-specific gadget
	   drivers that have more specific information.
