77d8f110ac usb: host: xhci-plat: add quirks member into struct xhci_plat_priv
To simplify adding xhci->quirks instead of the .init_quirk()
function, this patch adds a new parameter "quirks" into
the struct xhci_plat_priv.

9ed64195e3 USB: host: xhci: 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.

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.

c06fac7fa0 usb: host: xhci: plat: finally get rid of xhci_plat_type_is()
Now that there are no more users for
xhci_plat_type_is(), we can safely remove it.

7eca937ec8 usb: xhci: plat: add ->plat_start() and ->init_quirk() methods
these two methods will be used to hide
platform-specific details so we can get rid of
xhci_plat_type_is() in a later patch.

f9a85f6e61 usb: host: xhci-plat: Make enum xhci_plat_type start at a non zero value
Otherwise generic-xhci and xhci-platform which have no data get wrongly
detected as XHCI_PLAT_TYPE_MARVELL_ARMADA by xhci_plat_type_is().

This fixes a regression in v4.5 for STiH407 family SoC's which use the
synopsis dwc3 IP, whereby the disable_clk error path gets taken due to
wrongly being detected as XHCI_PLAT_TYPE_MARVELL_ARMADA and the hcd never
gets added.

I suspect this will also fix other dwc3 DT platforms such as Exynos,
although I've only tested on STih410 SoC.

setting, and need a new firmware.
