2008-05-14USB: atmel_usba_udc fixes, mostly disconnect()David Brownell
Various fixes to Atmel's high speed UDC driver. * Issue some missing disconnect() calls. Currently they are only made when VBUS power goes away (on boards where the driver can sense such changes), but that's not enough for gadget drivers to clean out all the state that's needed. Missing calls were: - After USB reset, before starting enumeration. - When unregistering a gadget driver, before unbind(). * Don't assume gadget drivers provide disconnect callbacks; make sure to not call through a null pointer! * When the driver doesn't provide an unbind() callback, refuse to unregister it. Also remove two bogus "error" messages: * Related to mis-handling of disconnect() ... don't emit error messages for disconnect() handlers that disable endpoints. All of them should be doing that; the problem is (unfixed) oddness in atmel_usba_udc. * Don't emit a diagnostic for a curious and transient nonfatal error that shows up sometimes with EP0. Those messages spammed syslog, for no good reason.

2008-05-14USB: serial gadget: descriptor cleanupDavid Brownell
Bugfix some serial gadget descriptors: - Stop mangling the low bits (controller type ID) of bcdDevice; just use the high bits for a driver revision code. - Serial numbers that aren't specific to individual devices are useless; stop reporting "0" for this. - Since it's not part of a CDC-conformant function, the "bulk only" configuration shouldn't be using "CDC Data" as its interface class.

2008-05-14USB: serial gadget: simplify endpoint handlingDavid Brownell
Switch serial gadget away from a *very* old idiom: just remember the endpoints we'll be using, instead of looking them up by name each time. This is a net code and data (globals) shrink. Also fix a small memory leak in the rmmod path, by working the same as the disconnect code.

2008-05-14USB: serial gadget: remove needless data structureDavid Brownell
This removes a needless data structure from the serial gadget code; it's a small code shrink, and a larger data shrink. Since "struct usb_request" already has a "struct list_head" reserved for use by gadget drivers, the serial gadget code doesn't need to allocate wrapper structs to hold that list ... it can (and should!) just use the list_head provided for that exact use.

2008-05-14USB: serial gadget: cleanup/reorgDavid Brownell
Some cleanup/reorg of g_serial ... simplifying it, and disentangling its structure so morphing it into a "function" driver (combinable with other interfaces) should be less painful. - Remove most forward declarations * put tty and gadget driver structs after their contents * snug module init/exit decls next to their functions * reordered some functions - Other cleanup: * convert a funky macro to an inline function * snug up module params next to their declarations * add missing driver.owner * add separator lines between major driver sections - Add comments re potential parameter/#define changes: * only supports one port (shrank GS_NUM_PORTS) * changing from 9600-8-N-1 affects multiple sites - Remove net2280-specific optimization ... it was being done way too late, can be done by net2280 module options, and in any case doesn't matter at any sane serial data rates. There are no behavioral changes, but the macro thing saves I-space.

2008-02-08usb: net2280 can't have a function called show_registers()David Howells
net2280 can't have a function called show_registers() because this can produce a namespace clash with an arch function of the same name. All this driver's functions and variables should really be prefixed with "net2280_" to avoid such a problem in future.

2008-02-01USB: Use menuconfig objectsDenis Cheng
commit 04d06ad0f1fdb499af84ae3d7969e2136a462f38 have added menuconfig support for the whole USB Kconfig, but there are still menuconfig need for usb/serial, usb/atm, and usb/gadget, so that the user can disable all the options in that menu at once instead of having to disable each option separately.

2008-02-01USB: at91_udc uses generic GPIO calls; minor cleanupDavid Brownell
Various small at91_udc cleanups: - Use generic GPIO calls, not older platform-specific ones - Use gpio_request()/gpio_free() - Use VERBOSE_DEBUG convention, not older VERBOSE - Fix sparse complaint about parameter type (changed to gfp_t) - Add missing newline to some rarely-seen debug messages - Fix some old cleanup bugs on probe() fault paths Also add a mechanism whereby rm9200 gpios can drive the D+ pullup through an inverting transistor, based on a patch from Steve Birtles. Most UDC drivers supporting a GPIO based pullup should probably have such an option, but testing it requries such a board in hand!

2008-02-01USB: gadget: at91_udc minor fix (there is no number six)David Brownell
Fix a small glitch noted by Yannick Cote. There is no endpoint number six, so if a (broken) host wrongly tried to change or read status of that endpoint, the driver could access reserved register space.
