Add <linux/usb/composite.h> interfaces for composite gadget drivers, and basic implementation support behind it: - struct usb_function ... groups one or more interfaces into a function managed as one unit within a configuration, to which it's added by usb_add_function(). - struct usb_configuration ... groups one or more such functions into a configuration managed as one unit by a driver, to which it's added by usb_add_config(). These operate at either high or full/low speeds and at a given bMaxPower. - struct usb_composite_driver ... groups one or more such configurations into a gadget driver, which may be registered or unregistered. - struct usb_composite_dev ... a usb_composite_driver manages this; it wraps the usb_gadget exposed by the controller driver. This also includes some basic kerneldoc. How to use it (the short version): provide a usb_composite_driver with a bind() that calls usb_add_config() for each of the needed configurations. The configurations in turn have bind() calls, which will usb_add_function() for each function required. Each function's bind() allocates resources needed to perform its tasks, like endpoints; sometimes configurations will allocate resources too. Separate patches will convert most gadget drivers to this infrastructure. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
