The xhci-pci-renesas module exports symbols for xhci-pci to load the
RAM/ROM on renesas xhci controllers. We had dependency which works
when both the modules are builtin or modules.
But if xhci-pci is inbuilt and xhci-pci-renesas in module, we get below
linker error:
drivers/usb/host/xhci-pci.o: In function `xhci_pci_remove':
drivers/usb/host/xhci-pci.c:411: undefined reference to `renesas_xhci_pci_exit'
drivers/usb/host/xhci-pci.o: In function `xhci_pci_probe':
drivers/usb/host/xhci-pci.c:345: undefined reference to `renesas_xhci_check_request_fw'
Fix this by adding USB_XHCI_PCI having depends on USB_XHCI_PCI_RENESAS
|| !USB_XHCI_PCI_RENESAS so that both can be either inbuilt or modules.

This add a new driver for renesas xhci which is basically a firmware
loader for uPD720201 and uPD720202 w/o ROM. The xhci-pci driver will
invoke this driver for loading/unloading on relevant devices.
This patch adds a firmware loader for the uPD720201K8-711-BAC-A
and uPD720202K8-711-BAA-A variant. Both of these chips are listed
in Renesas' R19UH0078EJ0500 Rev.5.00 "User's Manual: Hardware" as
devices which need the firmware loader on page 2 in order to
work as they "do not support the External ROM".
The "Firmware Download Sequence" is describe in chapter
"7.1 FW Download Interface" R19UH0078EJ0500 Rev.5.00 page 131.
The firmware "K2013080.mem" is available from a USB3.0 Host to
PCIe Adapter (PP2U-E card) "Firmware download" archive. An
alternative version can be sourced from Netgear's WNDR4700 GPL
archives.
The release notes of the PP2U-E's "Firmware Download" ver 2.0.1.3
(2012-06-15) state that the firmware is for the following devices:
- uPD720201 ES 2.0 sample whose revision ID is 2.
- uPD720201 ES 2.1 sample & CS sample & Mass product, ID is 3.
- uPD720202 ES 2.0 sample & CS sample & Mass product, ID is 2.

The driver hardcodes a hardware I/O address the way one should
generally not do, and this prevents both compile-testing, and
moving the platform to CONFIG_ARCH_MULTIPLATFORM.
Change the code to be independent of the machine headers
to allow those two. Removing the hardcoded address would
be hard and is not necessary, so leave that in place for now.

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

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

instead of defining all functions as static inlines,
let's move them to udc-core and export them with
EXPORT_SYMBOL_GPL, that way we can make sure that
only GPL drivers will use them.
As a side effect, it'll be nicer to add tracepoints
to the gadget API.
While at that, also fix Kconfig dependencies to
avoid randconfig build failures.

Here's the big pull request for USB and PHY drivers for 4.7-rc1
Full details in the shortlog, but it's the normal major gadget driver
updates, phy updates, new usbip code, as well as a bit of lots of other
stuff.
All have been in linux-next with no reported issues.

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.

This is almost all under drivers/usb/dwc2/. Many
changes to the host side implementation of dwc2 have
been done by Douglas Anderson.
We also have USB 3.1 support added to the Gadget
Framework and, because of that work, dwc3 got
support to Synopsys new DWC_usb31 IP core.
Other than these 2 important series, we also have
the usual collection of non-critical fixes,
Documentation updates, and minor changes all over
the place.

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.

Make use of ARCH_RENESAS in place of ARCH_SHMOBILE.
This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.
