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.

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.

dwc3 revisions <=3.00a have a limitation where Port Disable command
doesn't work. Set the quirk-broken-port-ped property for such
controllers so XHCI core can do the necessary workaround.

The dma ops for dwc3 devices are not set properly. So, use a
physical device sysdev, which will be inherited from parent,
to set the hardware / firmware parameters like dma.

Looks like we lost all changes related to
commit 9522def400 ("usb: dwc3: core: cleanup IRQ resources") in host.c
when Felipe's next branch was merged into Greg's next branch.

This patch removes "Enable USB3 LPM Capability" option from Kconfig
and adds snps,usb3_lpm_capable devicetree property instead of it.
USB3 LPM (Link Power Management) capability is hardware property, and
it's platform dependent, so if our hardware supports this feature, we
want rather to configure it in devicetree than having it as Kconfig option.

On some platforms a PHY may need to be handled also in the
host controller driver. Exynos5420 SoC requires some "PHY
tuning" based on the USB speed. This patch delivers dwc3's
PHYs to the xhci platform device when it's created.

All dwc3 based xhci host controller supports USB3.0 LPM functionality.
Therefore enable it in platform data for all dwc3 based xhci device if
DWC3_HOST_USB3_LPM_ENABLE is selected in Kconfig.

This is a Linux-only driver which makes use
of GPL-only symbols. It makes no sense to
maintain Dual BSD/GPL licensing for this driver.
Considering that the amount of work to use this
driver in any different operating system would likely
be as large as developing the driver from scratch and
considering that we depend on GPL-only symbols, we
will switch over to a GPL v2-only license.

This fix prevents a problem with dwc3 and host mode where
we were requesting the entire memory region in dwc3/core.c,
thus preventing xhci-plat from ever ioremapping its own address space.
