2011-07-08usb: gadget: add SS descriptors to Ethernet gadgetPaul Zimmerman
Add SuperSpeed descriptors to the Network USB function drivers. This has been lightly tested using a Linux host. I was able to ssh from device to host and host to device, no obvious problems seen. Signed-off-by: Paul Zimmerman <paulz@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2011-06-28usb: gadget: add usb_endpoint_descriptor to struct usb_epTatyana Brokhman
Change usb_ep_enable() prototype to use endpoint descriptor from usb_ep. This optimization spares the FDs from saving the endpoint chosen descriptor. This optimization is not full though. To fully exploit this change, one needs to update all the UDCs as well since in the current implementation each of them saves the endpoint descriptor in it's internal (and extended) endpoint structure.

2010-05-20USB: gadget: __init and __exit tags removedMichal Nazarewicz
__init, __initdata and __exit tags have have been removed from various files to make it possible for gadgets that do not use the __init/__exit tags to use those. Files in question are related to: * the core composite framework, * the mass storage function (fixing a section mismatch) and * ethernet driver (ACM, ECM, RNDIS).

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-03-02USB: Remove unsupported usb gadget driversChristoph Egger
A bunch of USB gadget drivers where never ported from the linux 2.4 series to 2.6 kernels. However there's some code still in the tree for them which isn't used and is probably untested for ages. As the chance of these drivers being forward ported is probably quite small now it might be time to get rid of them.

2008-10-16usb gadget: link fixes for network gadgetDavid Brownell
Change how the Ethernet/RNDIS gadget driver builds: don't use separate compilation, since it works poorly when key parts are library code (with init sections etc). Instead be as close as we can to "gcc --combine ...". This is a bit more complicated than most of the others because it had to resolve a few symbol collisions.

2008-07-21usb ethernet gadget: split CDC Ethernet functionDavid Brownell
This is a "CDC Ethernet" (ECM) function driver, extracted from the all-in-one Ethernet gadget driver. This is a good example of how to implement interface altsettings. In fact it's currently the only such example in the gadget stack, pending addition of OBEX support.
