The Faraday FOTG210 is a dual-mode OTG USB controller that can
act as host, peripheral or both. To be able to probe from one
hardware description and to follow the pattern of other dual-
mode controllers such as MUSB or MTU3 we need to collect the
two, currently completely separate drivers in the same
directory.

After this, users need to select the main symbol USB_FOTG210
and then each respective subdriver. We pave the road to
compile both drivers into the same kernel and select the
one we want to use at probe() time, and possibly add OTG
support in the end.

This patch doesn't do much more than create the new symbol
and collect the drivers in one place. We also add a comment
for the section of dual-mode controllers in the Kconfig
file so people can see what these selections are about.

Also add myself as maintainer as there has been little
response on my patches to these drivers.

The Octeon usb driver has been in staging for a long time and used in
Ubiquiti routers for a while now.
It's been built and then tested on real hardware with several usb devices
and it is proven to be stable and ready to be moved to its proper place
in the kernel tree.

Move it to drivers/usb/host and adjust its Makefile, Kconfig and defconfig
dependencies.

Many thanks to the developers who made it happen.

The omap usb drivers still rely on mach/*.h headers that
are explicitly or implicitly included, but all the required
definitions are now in include/linux/soc/ti/, so use those
instead and allow compile-testing on other architectures.

Introduces the Xen pvUSB frontend. With pvUSB it is possible for a Xen
domU to communicate with a USB device assigned to that domU. The
communication is all done via the pvUSB backend in a driver domain
(usually Dom0) which is owner of the physical device.

The pvUSB frontend is a USB hcd for a virtual USB host connector.

The code is taken from the pvUSB implementation in Xen done by Fujitsu
based on Linux kernel 2.6.18.

Changes from the original version are:
- port to upstream kernel
- put all code in just one source file
- move module to appropriate location in kernel tree
- adapt to Linux style guide
- minor code modifications to increase readability

Commit 1b00767fd8e1 ("MIPS: Remove PMC MSP71xx platform") deletes
./arch/mips/pmcs-msp71xx/Kconfig, including its config  MSP_HAS_USB.

Hence, since then, the corresponding EHCI support for on-chip PMC MSP71xx
USB controller is dead code. Remove this dead driver.

Select USB_GADGET Kconfig option in order to fix build failure which
happens because ChipIdea driver has a build dependency on both USB_GADGET
and USB_EHCI_HCD, while USB_EHCI_TEGRA force-selects the ChipIdea driver
without taking into account the tristate USB_GADGET dependency. It's not
possible to do anything about the cyclic dependency of the Kconfig
options, but USB_EHCI_TEGRA is now a deprecated option that isn't used
by defconfigs and USB_GADGET is wanted on Tegra by default, hence it's
okay to have a bit clunky workaround for it.

The ChipIdea driver now provides USB2 host mode support for NVIDIA Tegra
SoCs. The ehci-tegra driver is obsolete now, remove it and redirect the
older Kconfig entry to the CI driver.
