* USB: Remove superfluous "depends on USB_SERIAL" from Kconfig.Robert P. J. Day2008-04-25

* USB: ehci shutdown refactoredSarah Sharp2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors some shutdown code so it can be shared between ehci_stop() and ehci_shutdown(). This also fixes a couple potential bugs: - ehci_shutdown() was not locking ehci->lock before halting the HC. - ehci_shutdown() didn't disable the watchdog and IAA timers. - ehci_stop() was resetting the host controller when it may have been running, which the EHCI spec says "may result in undefined behavior". ehci_stop() was calling port_power() to turn off the ports, which waited 20ms after applying the port change. The msleep was for the case where the HC might take 20ms to turn the ports on; since we're shutting them off, we can avoid the msleep and just use ehci_turn_off_ports(). ehci_stop() doesn't need to clear the intr_enable register or revert ownership of the companion controllers to the BIOS, because the host controller reset should have done that. There might be a buggy host controller that doesn't follow the reset rules, but for now we assume it's redundant code and remove it. [ A subsequent patch will cancel the timers later ... this version carries forward existing bugs where timers could get re-armed after they're canceled. ] Signed-off-by: Sarah Sharp <sarah.a.sharp@intel.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: dummy-hcd: use dynamic allocation for platform_devicesAlan Stern2008-04-25
| | | | | | | | | | | | | | | | This patch (as1075) changes dummy-hcd to dynamically allocate its platform_device structures, using the core platform_device_alloc() interface. This is what it should have done all along, because the dynamically-allocated structures have a release method in the driver core and are therefore immune to being released after the module has been unloaded. Thanks to Richard Purdie for pointing out the need for this change.

* USB: gadget section fixesDavid Brownell2008-04-25
| | | | | | | | | | | | Restore some section annotations: they were switched to "__devinit" while they should have been "__init", because of bogus warnings. The warnings are now fixed, so the runtime footprint of various drivers can now shrink a bit. On ARMv5, it's about 600 bytes except for the Ethernet gadget, where it can save a bit more.

* USB: rework sysfs removal of interface filesAlan Stern2008-04-25
| | | | | | | | | | | | | | | | | | Removing an interface's sysfs files before unregistering the interface doesn't work properly, because usb_unbind_interface() will reinstall altsetting 0 and thereby create new sysfs files. This patch (as1074) removes the files after the unregistration is finished. It's not quite as clean, but at least it works. Also, there's no need to check if an interface has been registered before removing its sysfs files. If it hasn't been registered then the files won't have been created, so usb_remove_sysfs_intf_files() will simply do nothing.

* USB: OHCI: host-controller resumes leave root hub suspendedAlan Stern2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | Drivers in the ohci-hcd family should perform certain tasks whenever their controller device is resumed. These include checking for loss of power during suspend, turning on port power, and enabling interrupt requests. Until now these jobs have been carried out when the root hub is resumed, not when the controller is. Many drivers work around the resulting awkwardness by automatically resuming their root hub whenever the controller is resumed. But this is wasteful and unnecessary. To simplify the situation, this patch (as1066) adds a new core routine, ohci_finish_controller_resume(), which can be used by all the OHCI-variant drivers. They can call the new routine instead of resuming their root hubs. And ohci-pci.c can call it instead of using its own special-purpose handler.

* USB: clarify usage of hcd->suspend/resume methodsAlan Stern2008-04-25
| | | | | | | | | | | | | | | The .suspend and .resume method pointers in struct usb_hcd have not been fully understood by host-controller driver writers. They are meant for use with PCI controllers; other platform-specific drivers generally should not refer to them. To try and clarify matters, this patch (as1065) renames those methods to .pci_suspend and .pci_resume. It eliminates corresponding dead code and bogus references in the ohci-ssb and u132-hcd drivers.

* USB: root hubs don't lie about their number of TTsAlan Stern2008-04-25
| | | | | | | | | | | | | Currently EHCI root hubs enumerate with a bDeviceProtocol code indicating that they possess a Transaction Translator. However the vast majority of controllers do not; they rely on a companion controller to handle full- and low-speed communications. This patch (as1064) changes the root-hub device descriptor to match the actual situation. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: OHCI: fix bug in controller resumeAlan Stern2008-04-25
| | | | | | | | | | | | | | | This patch (as1063) fixes a bug in the way ohci-hcd resumes its controllers. It leaves the Master Interrupt Enable bit turned off. If the root hub is resumed immediately this won't matter. But if the root hub is suspended (say because no devices are plugged in), it won't ever wake up by itself.
