* usb: gadget: consider link speed for bMaxPowerSebastian Andrzej Siewior2013-01-101-1/+1
| | | | | | | | | | | | | | | The USB 2.0 specification says that bMaxPower is the maximum power consumption expressed in 2 mA units and the USB 3.0 specification says that it is expressed in 8 mA units. This patch renames bMaxPower to MaxPower and the various /2 and *2 are removed. Before reporting the config descriptor, the proper value is computer based on the speed, all in-tree users are updated. MaxPower is also increased to u16 so we can store the nokia gadget value which is larger than the max value allowed for u8.

* usb: gadget: remove usb_gadget_controller_number()Sebastian Andrzej Siewior2012-09-101-15/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bcdDevice field is defined as |Device release number in binary-coded decimal in the USB 2.0 specification. We use this field to distinguish the UDCs from each other. In theory this could be used on the host side to apply certain quirks if the "special" UDC in combination with this gadget is used. This hasn't been done as far as I am aware. In practice it would be better to fix the UDC driver before shipping since a later release might not need this quirk anymore. There are some driver in tree (on the host side) which use the bcdDevice field to figure out special workarounds for a given firmware revision. This seems to make sense. Therefore this patch converts all gadgets (except a few) to use the kernel version instead a random 2 or 3 plus the UDC number. The few that don't report kernel's version are: - webcam This one reports always a version 0x10 so allow it to do so in future. - nokia This one reports always 0x211. The comment says that this gadget works only if the UDC supports altsettings so I added a check for this. - serial This one reports 0x2400 + UDC number. Since the gadget version is 2.4 this could make sense. Therefore bcdDevice is 0x2400 here. I also remove various gadget_is_<name> macros which are unused. The remaining few macros should be moved to feature / bug bitfield.

* usb: gadget: Provide a default implementation of default manufacturer stringSebastian Andrzej Siewior2012-09-101-1/+0
| | | | | | | | | | | | | | | | | Some gadgets provide custom entry here. Some may override it with an etntry that is also created by composite if there was no value sumbitted at all. This patch removes all "custom manufacturer" strings which are the same as these which are created by composite. Then it moves the creation of the default manufacturer string to usb_composite_overwrite_options() in case no command line argument has been used and the entry is still an empty string. By doing this we get rid of the global variable "composite_manufacturer" in composite.

| | | | | | | | | | | | | | The index in usb_string array is defined by the gadget. The gadget can choose which index entry it assigns for the serial number and which the product name. The gadget has just to ensure that the descriptor contains the proper string id which is assigned by composite. If the composite layer knows the index of the "default" information which will be overwritten by module parameters, it can be used later to overwrite it.

| | | | | | | | | | | | | | As it turns out, Sam's comment was better than I initially assumed. This patch pushes as struct usb_composite_driver data structures into __refdata section to avoid a section missmatch report from modpost because the ->bind() can be marked __init.

* usb: Provide usb_speed_string() functionMichal Nazarewicz2011-09-181-10/+1
| | | | | | | | | | | | | | | | | | | In a few places in the kernel, the code prints a human-readable USB device speed (eg. "high speed"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To mitigate this issue, this commit introduces usb_speed_string() function, which returns a human-readable name of provided speed. It also changes a few places switch was used to use this new function. This changes a bit the way the speed is printed in few instances at the same time standardising it.

* usb: gadget: defer setting maxpacket till ->setup()Sebastian Andrzej Siewior2011-07-011-2/+1
| | | | | | | | | | | | | | | | maxpacket is set by the udc driver for ep0 very early. This value is copied by the function gadget used later for the USB_DT_DEVICE and USB_DT_DEVICE_QUALIFIER query. This seems to work fine so far. For USB3 we need set a different value here. In SS speed it is 2^x with x=9 and in HS we set something <= 64. If the UDC starts in SS and continues in HS after the cable has been plugged it will report a too small value. There setting of this value is defered and taken automaticly from the ep0 pointer where the UDC driver can update it according to the speed it detected _after_ a cable has been plugged.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* USB: gadget driver unbind() is optional; section fixes; miscDavid Brownell2006-12-201-6/+6
| | | | | | | | | | | | | | | | | | Allow gadget drivers to omit the unbind() method. When they're statically linked, that's an appropriate memory saving tweak. Similarly, provide consistent/simpler handling for a should-not-happen error case: removing a peripheral controller driver when a gadget driver is still loaded. Such code dates back to early versions of the first implementation of the gadget API, and has never been triggered. Includes relevant section annotation fixs for gmidi.c, file_storage.c, and serial.c; we don't yet have an "init or exit" annotation. Also some whitespace fixes in gmidi.c (space at EOL, before tabs, etc). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] namespaces: utsname: use init_utsname when appropriateSerge E. Hallyn2006-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | In some places, particularly drivers and __init code, the init utsns is the appropriate one to use. This patch replaces those with a the init_utsname helper. Changes: Removed several uses of init_utsname(). Hope I picked all the right ones in net/ipv4/ipconfig.c. These are now changed to utsname() (the per-process namespace utsname) in the previous patch (2/7) [akpm@osdl.org: CIFS fix] Signed-off-by: Serge E.

* USB: gmidi: New USB MIDI Gadget class driver.Ben Williamson2006-09-271-0/+1337
This driver is glue between the USB gadget interface and the ALSA MIDI interface. It allows us to appear as a MIDI Streaming device to a host system on the other end of a USB cable. This includes linux/usb/audio.h and linux/usb/midi.h containing definitions from the relevant USB specifications for USB audio and USB MIDI devices. The following changes have been made since the first RFC posting: * Bug fixes to endpoint handling. * Workaround for USB_REQ_SET_CONFIGURATION handling, not understood yet. * Added SND and SND_RAWMIDI dependencies in Kconfig. * Moved usb_audio.h and usb_midi.h to usb/*.h * Added module parameters for ALSA card index and id. * Added module parameters for USB descriptor IDs and strings. * Removed some unneeded stuff inherited from zero.c, more to go. * Provide DECLARE_* macros for the variable-length structs. * Use kmalloc instead of usb_ep_alloc_buffer. * Limit source to 80 columns. * Return actual error code instead of -ENOMEM in a few places.
