7 # NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
9 # - Host systems (like PCs) need CONFIG_USB (with "A" jacks).
10 # - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks).
11 # - Some systems have both kinds of controllers.
13 # With help from a special transceiver and a "Mini-AB" jack, systems with
14 # both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG).
22 # - integrated/SOC controllers first
23 # - licensed IP used in both SOC and discrete versions
24 # - discrete ones (including all PCI-only controllers)
