usb gadget zero: split out source/sink config This splits the gadget zero "source/sink" configuration into a standalone "configuration driver", building on the composite gadget framework code. It doesn't yet pull the original code out of gadget zero or update how that driver is built. Neither this, nor its sibling "loopback" configuration, is a function driver that can be combined with other functions. (The host "usbtest" driver wouldn't know how to deal with that!) However the code becomes simpler because of this conversion, so it's a net win. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

USB: gadget: gadget zero uses new suspend/resume hooks Use the new device-level suspend/resume hooks for Gadget Zero; always enable them with the OTG test mode; and support remote wakeup on both configurations even in non-OTG mode. This ensures that both configurations can pass the USBCV remote wakeup tests when the OTG test mode is enabled. This changes behavior by adding autoresume support to the loopback config even in non-OTG mode; the test failure was that it didn't work in OTG mode.
