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 mvebu ARM64 SoCs no longer select PLAT_ORION. However Armada 37xx use
the Orion EHCI controller. This patch allows the Orion EHCI driver to be
built when ARCH_MVEBU is selected.

a lot of embeded system SOC (e.g. freescale T2080) have both
PCI and USB modules. But USB module is controlled by registers directly,
it have no relationship with PCI module.

when say N here it will not build PCI related code in USB driver.

The MIPS based MT7621 shares the same XHCI core as the newer generation of
ARM based SoCs. The driver works out of the box and we only need to make it
buildable in Kconfig.

Separate the Davinci OHCI host controller driver from ohci-hcd
host code so that it can be built as a separate driver module.

Including mach/* is frowned upon in device drivers, so get rid of it.

This replaces usb20_clk and code that pokes CFGCHIP2 with a proper phy
driver.

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.

Pull USB updates from Greg KH:
 "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"
