Address one open question in the composite gadget framework: Yes, we should have device-level suspend/resume callbacks in addition to the function-level ones. We have at least one scenario (with gadget zero in OTG test mode) that's awkward to handle without it.

To permit a userspace application to associate with WUSB devices using numeric association, control transfers to unauthenticated WUSB devices must be allowed.

NOP transceiver is used by all the usb transceiver which are mostly autonomous and doesn't require any programming or which are built into the usb ip itself.NOP transceiver only allocates the memory for struct xceiv and calls otg_set_transceiver() so function call to otg_get_transceiver() will return a valid transceiver.

Apparently the Configuration and Interface strings aren't used as often as the Vendor, Product, and Serial strings. In at least one device (a Saitek Cyborg Gold 3D joystick), attempts to read the Configuration string cause the device to stop responding to Control requests.

Add a new mechanism to the composite gadget framework, letting functions deactivate (and reactivate) themselves. Think of it as a refcounted wrapper for the software pullup control. A key example of why to use this mechanism involves functions that require a userspace daemon. Those functions shuld use this new mechanism to prevent the gadget from enumerating until those daemons are activated. Without this mechanism, hosts would see devices that malfunction until the relevant daemons start.

2008-07-22usb_serial: API all changeAlan Cox
USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-07-21usb gadget: composite gadget coreDavid Brownell
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.

2008-07-21usb gadget: descriptor copying supportDavid Brownell
Define three new descriptor manipulation utilities, for use when setting up functions that may have multiple instances: usb_copy_descriptors() to copy a vector of descriptors usb_free_descriptors() to free the copy usb_find_endpoint() to find a copied version These will be used as follows. Functions will continue to have static tables of descriptors they update, now used as __initdata templates. When a function creates a new instance, it patches those tables with relevant interface and string IDs, plus endpoint assignments. Then it copies those morphed descriptors, associates the copies with the new function instance, and records the endpoint descriptors to use when activating the endpoints. When initialization is done, only the copies remain in memory. The copies are freed on driver removal. This ensures that each instance has descriptors which hold the right instance-specific data. Two instances in the same configuration will obviously never share the same interface IDs or use the same endpoints. Instances in different configurations won't do so either, which means this is slightly less memory-efficient in some cases. This also includes a bugfix to the epautoconf code that shows up with this usage model. It must replace the previous endpoint number when updating the template descriptors, not just mask in a few more bits.

2008-04-24USB: defines for USB "Link Power Management" (LPM) ECNDavid Brownell
There's a new PM-related change notice for the USB 2.0 specification called "Link Power Management" (LPM). It defines a new "L1 Suspend" state which resembles the current (L2) suspend state, except that it can be entered and exited much more quickly. It should thus be more useful for runtime PM, even though it doesn't mandate reduced power draw from VBUS. This patch provides the relevant #defines for usbcore. Actually implementing these mechanisms requires host silicon that can generate new USB packets, plus hubs handling some new requests and peripherals which understand the new packets.
