The ehci controller found in some Broadcom switches with integrated SoCs
has an issue which causes a soft lockup with large transfers like you
see when running ext4 on USB3 flash drive.
Port the fix from the Broadcom XLDK to increase the OUT_THRESHOLD to
avoid the problem.

Use the newly introduced pm_ptr() macro, and mark the suspend/resume
functions __maybe_unused. These functions can then be moved outside the
CONFIG_PM_SUSPEND block, and the compiler can then process them and
detect build failures independently of the config. If unused, they will
simply be discarded by the compiler.

Since EHCI/OHCI controllers on R-Car Gen3 SoCs are possible to
be getting stuck very rarely after a full/low usb device was
disconnected. To detect/recover from such a situation, the controllers
require a special way which poll the EHCI PORTSC register and changes
the OHCI functional state.
So, this patch adds a polling timer into the ehci-platform driver,
and if the ehci driver detects the issue by the EHCI PORTSC register,
the ehci driver removes a companion device (= the OHCI controller)
to change the OHCI functional state to USB Reset once. And then,
the ehci driver adds the companion device again.

The USB HCD core driver parses the device-tree node for "phys" and
"usb-phys" properties. It also manages the power state of these PHYs
automatically.
However, drivers may opt-out of this behavior by setting "phy" or
"usb_phy" in struct usb_hcd to a non-null value. An example where this
is required is the "Qualcomm USB2 controller", implemented by the
chipidea driver. The hardware requires that the PHY is only powered on
after the "reset completed" event from the controller is received.
A follow-up patch will allow the USB HCD core driver to manage more than
one PHY. Add a new "skip_phy_initialization" bitflag to struct usb_hcd
so drivers can opt-out of any PHY management provided by the USB HCD
core driver.
This also updates the existing drivers so they use the new flag if they
want to opt out of the PHY management provided by the USB HCD core
driver. This means that for these drivers the new "multiple PHY"
handling (which will be added in a follow-up patch) will be disabled as
well.

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.

The Rockchip rk3288 EHCI controller doesn't properly detect
the case when a device is removed during suspend. Specifically,
when usb resume from suspend, the EHCI controller maintaining
the USB state (FLAG_CF is 1, Current Connect Status is 1),
but a USB device (like a USB camera on rk3288) may have been
disconnected actually.
Let's add a quirk to force ehci to go into the
usb_root_hub_lost_power() path and reset after resume.
This should generally reset the whole controller and all
ports and initialize everything cleanly again, and bring
the devices back up.
As part of this, rename the "hibernation" paramter of
ehci_resume() to force_reset since hibernation is simply
another case where we can't trust the autodetected status
and need to force a reset of devices.

The ehci-platform driver checks for misconfigurations in cases where
the Device Tree data specifies big-endian registers or descriptors but
the corresponding driver config settings have not been enabled. As
Jonas Gorski suggested, we may as well apply the same check to general
platform data too.
This requires moving the code that sets the big-endian quirk flags
from the ehci_platform_reset() routine into ehci_platform_probe(), and
moving the checks out of the DT-specific "if" statement clause.
The patch also changes the text of the error messages in an attempt to

The initial versions of the devicetree enablement patches for ehci-platform
used "ehci-platform" as compatible string. However this was disliked by various
reviewers because the platform bus is a Linux invention and devicetree is
supposed to be OS agnostic. After much discussion I gave up, added a:
"depends on !PPC_OF" to Kconfig to avoid a known conflict with PPC-OF platforms
and went with the generic usb-ehci as requested.
In retro-spect I should have chosen something different, the dts files for many
existing boards already claim to be compatible with "usb-ehci", ie they have:
compatible = "ti,ehci-omap", "usb-ehci";
In theory this should not be a problem since the "ti,ehci-omap" entry takes
presedence, but in practice using a conflicting compatible string is an issue,
because it makes which driver gets used depend on driver registration order.
This patch changes the compatible string claimed by ehci-platform to
"generic-ehci", avoiding the driver registration / module loading ordering
problems, and removes the "depends on !PPC_OF" workaround.

Currently ehci-platform is only used in combination with devicetree when used
with some Via socs. By extending it to (optionally) get clks and a phy from
devicetree, and enabling / disabling those on power_on / off, it can be used
more generically. Specifically after this commit it can be used for the
ehci controller on Allwinner sunxi SoCs.
Since ehci-platform is intended to handle any generic enough non pci ehci
device, add a "usb-ehci" compatibility string.
There already is a usb-ehci device-tree bindings document, update this
with clks and phy bindings info.
Although actually quite generic so far the via,vt8500 compatibilty string
had its own bindings document. Somehow we even ended up with 2 of them. Since
these provide no extra information over the generic usb-ehci documentation,
this patch removes them.
The ehci-ppc-of.c driver also claims the usb-ehci compatibility string,
even though it mostly is ibm,usb-ehci-440epx specific. ehci-platform.c is
not needed on ppc platforms, so add a !PPC_OF dependency to it to avoid
2 drivers claiming the same compatibility string getting build on ppc.

Pull ARM SoC specific changes from Arnd Bergmann:
"These changes are all to SoC-specific code, a total of 33 branches on
17 platforms were pulled into this. Like last time, Renesas sh-mobile
is now the platform with the most changes, followed by OMAP and
EXYNOS.
Two new platforms, TI Keystone and Rockchips RK3xxx are added in this
branch, both containing almost no platform specific code at all, since
they are using generic subsystem interfaces for clocks, pinctrl,
interrupts etc. The device drivers are getting merged through the
respective subsystem maintainer trees.
One more SoC (u300) is now multiplatform capable and several others
(shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
towards that goal with this series but need more work.
Also noteworthy is the work on PCI here, which is traditionally part
of the SoC specific code. With the changes done by Thomas Petazzoni,
we can now more easily have PCI host controller drivers as loadable
modules and keep them separate from the platform code in
drivers/pci/host. This has already led to the discovery that three
platforms (exynos, spear and imx) are actually using an identical PCIe
host controller and will be able to share a driver once support for
spear and imx is added."

Sometimes there is a need to initialize some non-standard registers mapped to
the EHCI region before accessing the standard EHCI registers. Add pre_setup()
method with 'struct usb_hcd *' parameter to be called just before ehci_setup()
to the 'ehci-platform' driver's platform data for this purpose...
While at it, add the missing incomplete declaration of 'struct platform_device'
to <linux/usb/ehci_pdriver.h>...
The patch has been tested on the Marzen and BOCK-W boards.

'vt8500_ehci_ids' is always compiled in. Hence use of
of_match_ptr is unnecessary.

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).
Thus, it is not needed to manually clear the device driver data to NULL.

This lets us use the ehci-platform driver on platforms without special
requirements for their ehci controllers. In particular, this is true
for the vt8500/wm8x50 platforms, which currently have a separate
driver that causes problems with multiplatform configurations.

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.
