USB: EHCI: ehci-mv: switch the HSIC HCI to HSIC mode Turns out the undocumented and reserved bits of port status/control register of the root port need to be set to use the HCI in HSIC mode. Typically the firmware does this, but that is not always good enough, because the bits get lost if the HSIC clock is disabled (e.g. when ehci-mv is build as a module). This supplements commit 7b104f890ade ("USB: EHCI: ehci-mv: add HSIC support").

USB: host: ehci: Remove redundant license text Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/ It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

Revert "USB: EHCI: support running URB giveback in tasklet context" This reverts commit 428aac8a81058e2303677a8fbf26670229e51d3a. This isn't quite ready for 3.12, we need some more EHCI driver changes that are just now showing up. So revert this for now, and queue it up later for 3.13.

USB: EHCI: support running URB giveback in tasklet context All 4 transfer types can work well on EHCI HCD after switching to run URB giveback in tasklet context, so mark all HCD drivers to support it.

USB: ehci-mv: remove unnecessary platform_set_drvdata() The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound).

Merge tag 'usb-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.10 merge window Here is the big Gadget & PHY pull request. Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.
