* usb: Add module.h to drivers/usb consumers who really use it.Paul Gortmaker2011-10-31
| | | | | | | | | The situation up to this point meant that module.h was pretty much everywhere, regardless of whether you asked for it or not. We are fixing that, so give the USB folks who want it an actual include of it. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* usb: gadget: add max_speed to usb_composite_driverTatyana Brokhman2011-07-01
| | | | | | | | | | | | | | | This field is used by the Gadget drivers to specify the maximum speed they support, meaning: the maximum speed they can provide descriptors for. The driver speed will be set in consideration of this value.

* usb gadget: don't save bind callback in struct usb_configurationUwe Kleine-König2010-10-22
| | | | | | | | | | | | | The bind function is most of the time only called at init time so there is no need to save a pointer to it in the configuration structure. This fixes many section mismatches reported by modpost.

* USB: Revert "USB: gadget: section mismatch warning fixed"Michal Nazarewicz2010-10-22
| | | | | | | | | | | | | This reverts a commit which proposed an invalid solution for a section mismatch. Next 3 commits will fix it correctly.

* USB: gadget: section mismatch warning fixedMichal Nazarewicz2010-08-10
| | | | | | | | | | | | | In may gadgets bind and bind like functions were in a init section as they were only run during initialisation. However, being callback functions they were referenced from structures in “normal” sections. Changing the tag from “__init” to “__ref” fixes the warnings.

* usb gadget: USB_GADGET_VBUS_DRAW Kconfig optionDavid Brownell2008-10-17
| | | | | | | | | | | | | | | | | | Offer a "how much VBUS power to request" configuration option for USB gadgets that aren't using board-specific customization of their gadget or (composite) configuration drivers. Also remove a couple pointless "depends on USB_GADGET" bits from the Kconfig text; booleans inside an "if USB_GADGET" will already have that dependency. Based on a patch from Justin Clacherty.

* usb gadget: link fixes for cdc composite gadgetDavid Brownell2008-10-16
| | | | | | | | | | | Change how the CDC Composite 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 ...". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Rename WARN() to WARNING() to clear the namespaceArjan van de Ven2008-07-25
| | | | | | | | | | | | | We want to use WARN() as a variant of WARN_ON(), however a few drivers are using WARN() internally. This patch renames these to WARNING() to avoid the namespace clash. A few cases were defining but not using the thing, for those cases I just deleted the definition.

* usb gadget: new "CDC Composite" gadget driverDavid Brownell2008-07-21
This is a simple example of a composite gadget, combining two Communications Class Device (CDC) functions: ECM and ACM. This provides a clear example of how the composite gadget framework is intended to work. It's surprising that MS-Windows (or at least, XP and previous) won't "just work" with something this simple... One /proc/bus/usb/devices listing looks like: T: Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 46 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=02(comm.)

All the highspeed-capable peripheral controllers with drivers now in the mainline kernel seem to support this, as does omap_udc. But many full speed controllers don't have enough endpoints, or (as with the PXA controllers) don't support altsettings. Lightly tested.
