usb: Bind devices to ACPI devices when possible

2012-05-12T00:06:13Z

Built-in USB devices will typically have a representation in the system ACPI tables. Add support for binding the two together so the USB code can make use of the associated methods. Signed-off-by: Matthew Garrett Signed-off-by: Lan Tianyu Signed-off-by: Greg Kroah-Hartman

USB: cleanup the handling of the PM complete call

2012-01-24T22:23:49Z

This eliminates the last instance of a function's behavior controlled by a parameter as Linus hates such things. Signed-off-by: Oliver Neukum Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: move usb_translate_errors to linux/usb.h

2011-11-15T18:47:40Z

Move usb_translate_errors from usb core to linux/usb.h as it is meant to be accessed from drivers. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

xHCI: set USB2 hardware LPM

2011-09-26T22:51:10Z

If the device pass the USB2 software LPM and the host supports hardware LPM, enable hardware LPM for the device to let the host decide when to put the link into lower power state. If hardware LPM is enabled for a port and driver wants to put it into suspend, it must first disable hardware LPM, resume the port into U0, and then suspend the port.

usbcore: get BOS descriptor set

2011-09-26T22:51:08Z

This commit gets BOS(Binary Device Object Store) descriptor set for Super Speed devices and High Speed devices which support BOS descriptor. BOS descriptor is used to report additional USB device-level capabilities that are not reported via the Device descriptor. By getting BOS descriptor set, driver can check device's device-level capability such as LPM capability. Signed-off-by: Andiry Xu Signed-off-by: Sarah Sharp Signed-off-by: Greg Kroah-Hartman

usb: core: Change usb_create_sysfs_intf_files()' return type to void

2011-04-30T00:24:38Z

The usb_create_sysfs_intf_files() function always returned zero even if it failed to create sysfs fails. Since this is a desired behaviour there is no need to return return code at all. This commit changes function's return type (form int) to void. Signed-off-by: Michal Nazarewicz Cc: Sergey Senozhatsky Signed-off-by: Greg Kroah-Hartman

USB: Move runtime PM callbacks to usb_device_pm_ops

2011-03-18T18:55:36Z

USB defines usb_device_type pointing to usb_device_pm_ops that provides system-wide PM callbacks only and usb_bus_type pointing to usb_bus_pm_ops that provides runtime PM callbacks only. However, the USB runtime PM callbacks may be defined in usb_device_pm_ops which makes it possible to drop usb_bus_pm_ops and will allow us to consolidate the handling of subsystems by the PM core code.

USB: add helper to convert USB error codes

2011-01-23T03:35:38Z

This converts error codes specific to USB to generic error codes that can be returned to user space. Tests showed that it is so small that it is better inlined. Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman

USB: use the runtime-PM autosuspend implementation

2010-11-16T22:03:41Z

This patch (as1428) converts USB over to the new runtime-PM core autosuspend framework. One slightly awkward aspect of the conversion is that USB devices will now have two suspend-delay attributes: the old power/autosuspend file and the new power/autosuspend_delay_ms file. One expresses the delay time in seconds and the other in milliseconds, but otherwise they do the same thing. The old attribute can be deprecated and then removed eventually.

USB: convert to the runtime PM framework

2010-03-02T22:54:12Z

This patch (as1329) converts the USB stack over to the PM core's runtime PM framework. This involves numerous changes throughout usbcore, especially to hub.c and driver.c. Perhaps the most notable change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME instead of CONFIG_PM. Several fields in the usb_device and usb_interface structures are no longer needed. Some code which used to depend on CONFIG_USB_PM now depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header files). The only visible change in behavior should be that following a system sleep (resume from RAM or resume from hibernation), autosuspended USB devices will be resumed just like everything else. They won't remain suspended. But if they aren't in use then they will naturally autosuspend again in a few seconds. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman
