Greg Kroah-Hartman 229e368239 USB: gadget: udc: 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.

Greg Kroah-Hartman 5fd54ace47 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.

Raviteja Garimella 1b9f35adb0 usb: gadget: udc: Add Synopsys UDC Platform driver
This patch adds platform driver support for Synopsys UDC.

A new driver file (snps_udc_plat.c) is created for this purpose
where the platform driver registration is done based on OF
node.

Currently, UDC integrated into Broadcom's iProc SoCs (Northstar2
and Cygnus) work with this driver.

New members are added to the UDC data structure for having platform
device support along with extcon and phy support.

Kconfig and Makefiles are modified to select platform driver for
compilation.

Greg Kroah-Hartman ba7756d082 usb: changes for v4.12
With 51 non-merge commits, this is one of the smallest USB Gadget pull
 requests. Apart from your expected set of non-critical fixes, and
 other miscellaneous items, we have most of the changes in dwc3 (52.5%)
 with all other UDCs following with 34.8%.
 
 As for the actual changes, the most important of them are all the
 recent changes to reduce memory footprint of dwc3, bare minimum
 dual-role support on dwc3 and reworked endpoint count and
 initialization routines.

Raviteja Garimella 97b3ffa233 usb: gadget: udc: amd5536: split core and PCI layer
This patch splits the amd5536udc driver into two -- one that does
pci device registration and the other file that does the rest of
the driver tasks like the gadget/ep ops etc for Synopsys UDC.

This way of splitting helps in exporting core driver symbols which
can be used by any other platform/pci driver that is written for
the same Synopsys USB device controller.

The current patch also includes a change in the Kconfig and Makefile.
A new config option USB_SNP_CORE will be selected automatically when
any one of the platform or pci driver for the same UDC is selected.

Main changes:
- amd5536udc_pci.c: PCI device registration is moved to this file.

- amd5536udc.c:
  This file does rest of the core UDC fucntionality.
  9 symbols are exported so as to be used by amd5536udc_pci.c.
  Module parameter definitions are moved to header file.

- amd5536udc.h:
  Function declarations, module parameters definitions and few common
  header file includes are added to this file

- Kconfig:
  New USB_SNP_CORE option is added which will be auto selected when
  any pci or platform driver config option for the UDC is chosen.

- Makefile:
  Compiles the core and pci files separately.
