This commit adds support for HiSilicon STB xHCI host controller.
There are two xHCI host controllers on HiSilicon STB SoCs. Each
one requires additional configuration before exposing interface
compliant with xHCI.

Tegra's EHCI driver has a build dependency on Tegra's PHY driver and
currently Tegra's PHY driver is built only when Tegra's EHCI driver is
built. Add own Kconfig entry for the Tegra's PHY driver so that drivers
other than ehci-tegra (like ChipIdea UDC) could work with ehci-tegra
driver being disabled in kernels config by allowing user to manually

Here is the big set of USB and PHY driver patches for 4.17-rc1.
Lots of USB typeC work happened this round, with code moving from the
staging directory into the "real" part of the kernel, as well as new
infrastructure being added to be able to handle the different types of
"roles" that typeC requires.
There is also the normal huge set of USB gadget controller and driver
updates, along with XHCI changes, and a raft of other tiny fixes all
over the USB tree. And the PHY driver updates are merged in here as
well as they interacted with the USB drivers in some places.
All of these have been in linux-next for a while with no reported
issues.

The blackfin architecture is getting removed, and this is the last
remaining architecture specific setting, so the various hacks
can be removed now.
From all I can tell, there are no remaining in-tree users of the
driver, but it could be used by out-of-tree platform ports.
I've marked the driver as 'depends on COMPILE_TEST', short of
removing it outright.
It was originally written for some ARM PXA machines using the same
chip, but that platform never really worked and the code has been
removed a long time ago.

Move the Kconfig symbols USB_UHCI_BIG_ENDIAN_MMIO and
USB_UHCI_BIG_ENDIAN_DESC out of drivers/usb/host/Kconfig, which is
conditional upon USB && USB_SUPPORT, so that it can be freely selected
by platform Kconfig symbols in architecture code.
For example once the MIPS_GENERIC platform selects are fixed in commit
2e6522c565 ("MIPS: Fix typo BIG_ENDIAN to CPU_BIG_ENDIAN"), the MIPS
32r6_defconfig warns like so:
warning: (MIPS_GENERIC) selects USB_UHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && USB)

Patchwork: https://patchwork.linux-mips.org/patch/18559/
xHCI compatible USB host controllers(i.e. super-speed USB3 controllers)
can be implemented with the Debug Capability(DbC). It presents a debug
device which is fully compliant with the USB framework and provides the
equivalent of a very high performance full-duplex serial link. The debug
capability operation model and registers interface are defined in 7.6.8
of the xHCI specification, revision 1.1.
The DbC debug device shares a root port with the xHCI host. By default,
the debug capability is disabled and the root port is assigned to xHCI.
When the DbC is enabled, the root port will be assigned to the DbC debug
device, and the xHCI sees nothing on this port. This implementation uses
a sysfs node named <dbc> under the xHCI device to manage the enabling
and disabling of the debug capability.
When the debug capability is enabled, it will present a debug device
through the debug port. This debug device is fully compliant with the
USB3 framework, and it can be enumerated by a debug host on the other
end of the USB link. As soon as the debug device is configured, a TTY
serial device named /dev/ttyDBC0 will be created.

This driver is no longer needed and can be removed. The reason why
it's safe to remove this driver is that most omap devices don't have a
USB low-speed or full-speed compatible PHY installed and configured
with drivers/mfd/omap-usb-host.c. This means that devices like
beagleboard and pandaboard need to use a high-speed USB hub in order
to use devices like keyboard and mice.
Currently the only known configured for a full-speed PHY is the
mdm6600 modem on droid 4 and I've verified it works just fine with
ohci-platform.

The Aspeed 2400/2500 families have a variant of UHCI which requires
some quirks to the driver to work:
- The register offsets are different. We add a remapping helper.
- All accesses have to be done via 32-bit loads and stores. We
force all accessors to use readl/writel. This is of no consequence
for reads as we never read "in the middle" of a register. For writes
it also works fine as the registers only actually implement the bits
we try to write (16-bit for the registers accessed with writew and
8-bit for the register accessed with writeb), so always using a
32-bit write will have no negative effect. We never do partial writes.
- The resume detect interrupt is broken
- The number of ports is (optionally) provided via the device-tree

The firmware of R-Car USB 3.0 host controller will control the reset.
So, if the xhci driver doesn't do firmware downloading (e.g. kernel
configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR
is not set), the reset of USB 3.0 host controller doesn't work
correctly. Then, the host controller will cause long wait in
xhci_reset() because the CMD_RESET bit of op_regs->command is not
cleared for 10 seconds.
So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM
and CONFIG_USB_XHCI_RCAR.

Add support for the on-chip XUSB controller present on Tegra SoCs. This
controller, when loaded with external firmware, exposes an interface
compliant with xHCI. This driver loads the firmware, starts the
controller, and is able to service host-specific messages sent by the
controller's firmware.
The controller also supports USB device mode as well as powergating
of the SuperSpeed and host-controller logic when not in use, but
support for these is not yet implemented.

The USB_FSL_MPH_DR_OF symbol is used to ensure the code that interprets
the DR device node is built whenever one of the two drivers (EHCI or
UDC) for the platform is enabled. However, if CONFIG_USB is disabled
and we only support gadget mode, this causes a Kconfig warning:
warning: (USB_FSL_USB2) selects USB_FSL_MPH_DR_OF which has unmet direct dependencies (USB_SUPPORT && USB)
We can avoid this warning by simply no longer using the symbol,
and making sure we enter the drivers/usb/host/ directory when
the UDC driver is enabled that needs the file, and then we use
Makefile syntax to ensure the file is built-in if needed.
There is currently a dependency on CONFIG_OF, but this is redundant,
as we already know that this is set unconditionally for the platforms
that use this driver.

Here's a single-SoC topic branch that we've staged separately. Mainly
because it was hard to sort the branch contents in a way that fit our
existing branches due to some refactorings.
The code has been in -next for quite a while, but we staged it in arm-soc
a bit late, which is why we've kept it separate from the other updates
and are sending it separately here.

There some vendor quirks for MTK xhci host controller:
1. It defines some extra SW scheduling parameters for HW
to minimize the scheduling effort for synchronous and
interrupt endpoints. The parameters are put into reseved
DWs of slot context and endpoint context.
2. Its IMODI unit for Interrupter Moderation register is
8 times as much as that defined in xHCI spec.
3. Its TDS in Normal TRB defines a number of packets that
remains to be transferred for a TD after processing all
Max packets in all previous TRBs.

For historic reasons, the tegra platform selects USB_ULPI from architecture
code, but that hasn't really made sense for a long time, as the only
user of that code is the Tegra EHCI driver that has its own Kconfig
symbol.
This removes the 'select' statements from mach-tegra and drivers/soc/tegra
and adds them with the device driver that actually needs them.

Right now xhci-plat-hcd can be built when using one of platform specific
drivers only (mvebu/rcar). There shouldn't be such limitation as some
platforms may not require any quirks and may want to just use a generic

The Octeon OHCI is now supported by the ohci-platform driver, and
USB_OCTEON_OHCI is marked as deprecated. However, it is currently
still necessary to enable it in order to select
USB_OHCI_BIG_ENDIAN_MMIO. Make CPU_CAVIUM_OCTEON select that as well,
so that USB_OCTEON_OHCI is really obsolete.
The old ohci-octeon and ehci-octeon drivers also only enabled big-endian
MMIO in case the CPU was big-endian. Make the selections of
USB_EHCI_BIG_ENDIAN_MMIO and USB_OHCI_BIG_ENDIAN_MMIO conditional, to
match this.

The most important bits are a ton of new documentation for

several improvements to the old net2280 UDC driver, and
some minor tracepoint improvements to dwc3.
Other than that, a big list of minor cleanups, smaller bugfixes

The PPC_OF is a ppc specific option which is used to mean that the
firmware device tree access functions are available. Since all the
ppc platforms have a device tree, it is aways set to 'y' for ppc.
So it makes no sense to keep a such option in the current kernel.
Replace it with PPC
