2013-01-07Merge tag 'fixes-for-v3.8-rc2' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe says: usb: fixes for v3.8-rc2 Here is the first set of fixes for v3.8-rc cycle. There is a build fix for musb's dsps glue layer caused by some header cleanup on the OMAP tree. Marvel's USB drivers got a fix up for clk API usage switching over to clk_prepare() calls. u_serial has a bug fix for a missing wake_up() which would make gs_cleanup() wait forever for gs_close() to finish. A minor bug fix on dwc3's debugfs interface which would make us read wrong addresses when dumping all registers. dummy_hcd learned how to enumerate g_multi. s3c-hsotg now understands that we shouldn't kfree() memory allocated with devm_*. Other than that, there are a bunch of other minor fixes on renesas_usbhs, tcm_usb_gadget and amd5536udc. All patches have been pending on mailing for many weeks and shouldn't cause any problems.

2012-12-13usb: gadget: dummy: fix enumeration with g_multiSebastian Andrzej Siewior
If we do have endpoints named like "ep-a" then bEndpointAddress is counted internally by the gadget framework. If we do have endpoints named like "ep-1" then bEndpointAddress is assigned from the digit after "ep-". If we do have both, then it is likely that after we used up the "generic" endpoints we will use the digits and thus assign one bEndpointAddress to multiple endpoints. This theory can be proofed by using the completely enabled g_multi. Without this patch, the mass storage won't enumerate and times out because it shares endpoints with RNDIS. This patch also adds fills up the endpoints list so we have in total endpoints 1 to 15 in + out available while some of them are restricted to certain types like BULK or ISO. Without this change the nokia gadget won't load because the system does not provide enough (BULK) endpoints but it did before ep-a - ep-f were removed.

Unfortunately the DMA header patch had to be redone to avoid adding new multiplatform specific include paths, the other patches are just trivial compile fixes. Note that this does not yet contain the necessary Kconfig changes as we are still waiting for some drivers to get fixed up first. * tag 'tags/omap-for-v3.8/cleanup-multiplatform-no-clock-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h ASoC: OMAP: mcbsp fixes for enabling ARM multiplatform support watchdog: OMAP: fixup for ARM multiplatform support Conflicts due to surrounding changes in: arch/arm/mach-omap2/omap_hwmod_2420_data.c arch/arm/mach-omap2/omap_hwmod_2430_data.c Signed-off-by: Olof Johansson <olof@lixom.net>
2012-11-30ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.hTony Lindgren
Based on earlier discussions[1] we attempted to find a suitable location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP: DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion to dmaengine is complete. Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

2012-11-15TTY: call tty_port_destroy in the rest of driversJiri Slaby
After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.

While removing g_file_storage, we also had to fix a bunch of defconfigs which were still pointing to the old gadget. There's a big series getting us closer to being able to introduce our configfs interface. The series converts functions into loadable modules which will, eventually, be registered to the configfs interface. Other than that there's the usual typo fixes and miscelaneous cleanups all over the place."

storage_common.c has been used by both file_storage.c and f_mass_storage.c which had some different requirements in a few places. To accomodate for that, storage_common.c provided configuratian macros which were to be defined (or not) prior to the file #inclusion. Because now file_storage.c is no longer with us, we can remove support for those macros and thus simplify the code slightly.

2012-10-31usb: gadget: dummy_hcd: remove global the_controller variableSebastian Andrzej Siewior
The one thing that makes two UDCs+HCDs impossible is the global the_controller variable. This patch changes this. After device allocation we allocate the "the_controller" variable and pass it as platform_data to the UDC and its companion. We can have now multiple instances dummy hcd and therefore I change the limit from one to two. I was able to test this with g_ncm adn g_zero: |# lsusb |Bus 001 Device 002: ID 0525:a4a0 Netchip Technology, Inc. Linux-USB "Gadget Zero" |Bus 002 Device 002: ID 0525:a4a1 Netchip Technology, Inc.

2012-10-31usb: gadget: let f_* use usb_string_ids_tab() where it makes senseSebastian Andrzej Siewior
Instead of calling usb_string_id() multiple times I replace it with one usb_string_ids_tab(). The NULL pointer in struct usb_string with "" and are not overwritten in fail or unbind case. The conditional assignment remains because some gadgets recycle the string ID because the same descriptor (and string ID) is used if we have more than one config descriptor.

2012-10-31usb: gadget: always update HS/SS descriptors and create a copy of themSebastian Andrzej Siewior
HS and SS descriptors are staticaly created. They are updated during the bind process with the endpoint address, string id or interface numbers. After that, the descriptor chain is linked to struct usb_function which is used by composite in order to serve the GET_DESCRIPTOR requests, number of available configs and so on. There is no need to assign the HS descriptor only if the UDC supports HS speed because composite won't report those to the host if HS support has not been reached. The same reasoning is valid for SS. This patch makes sure each function updates HS/SS descriptors unconditionally and uses the newly introduced helper function to create a copy the descriptors for the speed which is supported by the UDC. While at that, also rename f->descriptors to f->fs_descriptors in order to make it more explicit what that means.

2012-10-31usb: gadget: uvc: fix error path in uvc_function_bind()Sebastian Andrzej Siewior
The "video->minor = -1" assigment is done in V4L2 by video_register_device() so it is removed here. Now. uvc_function_bind() calls in error case uvc_function_unbind() for cleanup. The problem is that uvc_function_unbind() frees the uvc struct and uvc_bind_config() does as well in error case of usb_add_function(). Removing kfree() in usb_add_function() would make the patch smaller but it would look odd because the new allocated memory is not cleaned up. However it is not guaranteed that if we call usb_add_function() we also get to the bind function. Therefore the patch extracts the conditional cleanup from uvc_function_unbind() applies to uvc_function_bind(). uvc_function_unbind() now contains only the complete cleanup which is required once everything has been registrated.
