2009-01-21usbnet: allow type check of devdbg arguments in non-debug buildSteve Glendinning
Improve usbnet's devdbg to always type-check diagnostic arguments, like dev_dbg (device.h). This makes no change to the resulting size of usbnet modules. This patch also removes an #ifdef DEBUG directive from rndis_wlan so it's devdbg statements are always type-checked at compile time.

gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.

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. 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>
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.

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.

2008-02-01USB: usb_serial: clean tty reference in the last closeAristeu Rozanski
When a usb serial adapter is used as console, the usb serial console driver bumps the open_count on the port struct used but doesn't attach a real tty to it (only a fake one temporaly). If this port is opened later using the regular character device interface, the open method won't initialize the port, which is the expected, and will receive a brand new tty struct created by tty layer, which will be stored in port->tty. When the last close is issued, open_count won't be 0 because of the console usage and the port->tty will still contain the old tty value. This is the last ttyUSB<n> close so the allocated tty will be freed by the tty layer. The usb_serial and usb_serial_port are still in use by the console, so port_free() won't be called (serial_close() -> usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled work (port->work, usb_serial_port_work()) will still run.

2008-02-01USB: add Printer Gadget DriverCraig W. Nadler
G_PRINTER: Adds a USB printer gadget driver for use in printer firmware. This adds a USB printer gadget driver for use in printer firmware. The printer gadget channels data between the USB host and a userspace program driving the print engine. The user space program reads and writes the device file /dev/g_printer to receive or send printer data. It can use ioctl calls to the device file to get or set printer status. Signed-off-by: Craig W.

Move headers usbnet.h and rndis_host.h to include/linux/usb and fix includes for drivers/net/usb modules. Headers are moved because rndis_wlan will be outside drivers/net/usb in drivers/net/wireless and yet need these headers.

2007-10-12USB: serial core should respect driver requirementsAlan Stern
This patch (as997) fixes a bug in the USB serial core. The core needs to pay attention to drivers' requirements regarding the number and type of endpoints a device has. At the same time, the patch changes the NUM_DONT_CARE constant (which is stored in a single-byte field) from -1 to a safer, unsigned value. It also improves the kerneldoc for several fields in the usb_serial_driver structure. Finally, the patch replaces a list_for_each() with list_for_each_entry().
