* usb: gadget: composite: add iSerialNumber to usb_composite_driverAndrzej Pietrasiewicz2012-05-102-2/+6
| | | | | | | | | | | | | Add iSerialNumber to usb_composite_driver to allow setting a default value. This is useful when the module is compiled-in. Then the composite_bind is executed at kernel boot and string id for iSerialNumber can be overridden even if there is no iSerialNumber kernel commandline parameter. If the string id is not overridden, then get_string will never attempt to look for the alternative string contents using cdev->serial_override.

* usb: gadget: composite: Add usb_remove_configBenoit Goby2012-05-102-20/+51
| | | | | | | | | | | | | | | | | | | Add usb_remove_config to unbind a configuration and remove it from the configs list. This allows implementing composite gadget drivers that can disconnect themself from the bus and that will later be re-enumerated with a different configuration. Gadget drivers must call usb_gadget_disconnect before calling this function to disable the pullup, disconnect the device from the host, and prevent the host from enumerating the device while we are changing the gadget configuration.

* USB: ohci-at91: add a reset function to fix race conditionNicolas Ferre2012-05-091-1/+10
| | | | | | | | | | | | | | | A possible race condition appears because we are not initializing the ohci->regs before calling usb_hcd_request_irqs(). We move the call to ohci_init() in hcd->driver->reset() instead of hcd->driver->start() to fix this. This was experienced when we share the same IRQ line between OHCI and EHCI controllers.

| | | | | | | | | | | Currently, endpoints are initialized in gadget start/stop methods, however for the new style gadgets it is expected that bind() can be called before controller's start(), and we need endpoints already initialized at that point.

* usb: gadget: ci13xxx: replace home-brewed logging with dev_{err,warn,info}Alexander Shishkin2012-05-092-109/+87
| | | | | | | | | | | | | | | Logging output in the driver is mostly done using custom err/warn/info macros which rely on the existence of the global variable _udc, which is a global reference to the udc controller structure. This reference will have to go in order to allow us to have more than one chipidea udc in the system. Thus, replace custom macros with dev_{err,warn,info} using the platform device where possible. The trace() macro, which is a nop by default is left for tracing purposes.

| | | | | | | | | | | Use lookup table instead of conditional macrodefinitions of register addresses. With two different possible register layouts and different register offsets, it's easiest to build a table with register addresses at probe time, based on the information supplied from the platform and device capabilities.

* USB: serial: rework usb_serial_register/deregister_drivers()Greg Kroah-Hartman2012-05-0856-400/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reworks the usb_serial_register_drivers() and usb_serial_deregister_drivers() to not need a pointer to a struct usb_driver anymore. The usb_driver structure is now created dynamically and registered and unregistered as needed. This saves lines of code in each usb-serial driver. All in-kernel users of these functions were also fixed up at this time. The pl2303 driver was tested that everything worked properly. Thanks for the idea to do this from Alan Stern.

* usb: gadget: ci13xxx: rename register layoutsAlexander Shishkin2012-05-084-133/+132
| | | | | | | | | | | | | | | | | | | | | | Currently, the register prefixes in the driver seem to be mixed: the capability registers are the ones that contain capability information, such as number of hardware endpoints, while the registers that are used to program the controller are called operational registers. Normally, capability registers start at 0x100 offset of the register window and are followed by operational registers. In some versions, however, capability registers start at 0x0 offset. This patch renames the register and adjusts their offsets appropriately, leaving the possibility of having a non-standard capability offset. I couldn't find any mentions of the TESTMODE register anywhere, so I suspect it might only be enabled in chipidea internal versions of the controller and I'm really inclined to remove it from the driver or at least hiding it behind a config option.

* usb-serial: clean up unneeded PM-related fieldsAlan Stern2012-05-077-24/+0
| | | | | | | | | | | | | | | This patch (as1551) cleans up the PM-related entries in the usb_driver structures of the various USB serial driver modules. Those entries are now filled in by the usb-serial core during driver registration, so they don't need to be initialized explicitly in the source code. The same is true of the one remaining no_dynamic_id entry. reset_resume remains a small problem, because the serial core doesn't support it. The patch ignores these entries.

* usb-serial: ftdi_sio: fix oops during autosuspendAlan Stern2012-05-071-2/+7
| | | | | | | | | | | | | | | | | | | | | | | This patch (as1550) fixes a bug in the usb-serial core that affects the ftdi_sio driver and most likely others as well. The core implements suspend and resume routines, but it doesn't store pointers to those routines in the usb_driver structures that it registers, even though it does set those drivers' supports_autosuspend flag. The end result is that when one of these devices is autosuspended, we try to call through a NULL pointer. The patch fixes the problem by setting the suspend and resume method pointers to the appropriate routines in the USB serial core, along with the supports_autosuspend field, in each driver as it is registered. This should be back-ported to all the stable kernels that have the new usb_serial_register_drivers() interface.

We also have some patches implementing a few extra Standard requests introduced by USB3 spec (Set SEL and Set Isoch Delay), as well as one patch, which has been pending for a long time, implementing LPM support. Last, but not least, we are splitting the host address space out of the dwc3 core driver otherwise xHCI won't be able to request_mem_region() its own address space. This patch is only needed because we are (as we should) re-using the xHCI driver, which is a completely separate module. Together with these three big changes, come a few extra preparatory patches which most move code around, define macros and so on, as well as a fix for Isochronous transfers which hasn't been triggered before.
