* usb gadget zero: use composite gadget frameworkDavid Brownell2008-07-21
| | | | | | | | | | | | | | | | | | Update Gadget Zero to use the more modular versions of the loopback and source/sink configuration drivers which build on the new gadget framework code. The core code is a LOT simpler, and it should be much easier now to understand how the parts fit together. The conversion is an overall source shrink in terms of this gadget, since it uses more midlayer support. However, it's an overall increase in object size because there's less sharing between the two configurations (improves code clarity) and because the midlayer is a bit more functional than this driver actually needs.

* usb: gadget zero style fixups (mostly whitespace)David Brownell2008-05-02
| | | | | | | | | | | | | | | Minor updates to "Gadget Zero". - Primarily these are whitespace updates to address the fact that since this was written, Documentation/CodingStyle was changed to disapprove of parts of the original coding style. - Update a few comments that weren't quite correct, notably mentioning the "autoresume" module parameter.

* USB: gadget code switches to pr_err() and friendsDavid Brownell2008-02-01
| | | | | | | | | | We now have pr_err(), pr_warning(), and friends ... start using them in the gadget stack instead of printk(KERN_ERR) and friends. This gives us shorter lines and somewhat increased readability. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: gadget: gadget zero cleanupsDavid Brownell2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | Clean up gadget zero, using newer APIs and conventions: - gadget_is_dualspeed() and gadget_is_otg() ... #ifdef removal - Remove many now-needless #includes - Use the VERBOSE_DEBUG convention - Some whitespace fixes. - A few comment updates - Plus a few other small cleanups: don't pass gfp_t around when it's always going to be GFP_ATOMIC, and do static init of serial number. Also go to straight GPL; there's no real point in dual licensing this stuff any more.

* USB: "sparse" cleanups for usb gadgetsDavid Brownell2007-07-30
| | | | | | | | | | This removes complaints about the gadget stack which are generated by the currrent "sparse": it doesn't like the fact that zero is the null pointer.

* usb gadget stack: remove usb_ep_*_buffer(), part 1David Brownell2007-07-12
| | | | | | | | | | | | | | | | | | | | | | Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers. This patch just removes the interface and its users; later patches will remove controller driver support. - This interface is invariably not implemented correctly in the controller drivers (e.g. using dma pools, a mechanism which post-dates the interface by several years). - At this point no gadget driver really *needs* to use it. In current kernels, any driver that needs such a mechanism could allocate a dma pool themselves. Removing this interface is thus a simplification and improvement. Note that the gmidi.c driver had a bug in this area; fixed. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

Changes: Removed several uses of init_utsname(). Hope I picked all the right ones in net/ipv4/ipconfig.c.

* [PATCH] USB: gadget section fixupsDavid Brownell2006-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | Recent section changes broke gadget builds on some platforms. This patch is the best fix that's available until better section markings exist: - There's a lot of cleanup code that gets used in both init and exit paths; stop marking it as "__exit". (Best fix for this would be an "__init_or_exit" section marking, putting the cleanup in __init when __exit sections get discarded else in __exit.) - Stop marking the use-once probe routines as "__init" since references to those routines are not allowed from driver structures. They're now marked "__devinit", which in practice is a net lose. (Best fix for this is likely to separate such use-once probe routines from the driver structure ... but in general, all busses that aren't hotpluggable will be forced to waste memory for all probe-only code.) In general these broken section rules waste an average of two to four kBytes per driver of code bloat ... because none of the relevant code can ever be reused after module initialization.

I think there was a bug in drivers/usb/gadget/inode.c because it used sizeof(*data) for the kmalloc() and sizeof(data) for the memset(), since sizeof(data) just returns the size for a pointer.

* [PATCH] USB: Gadget library: centralize gadget controller numbersDavid Brownell2005-09-08
| | | | | | | | | | | | | | | | This patch centralizes the assignment of bcdDevice numbers for different gadget controllers. This won't improve the object code at all, but it does save a lot of repetitive and error-prone source code ... and will simplify the work of supporting a new controller driver, since most new gadget drivers will no longer need patches (unless some hardware quirks limit USB protocol messaging).

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
