The Kconfig entries for USB_U132_HCD and USB_FTDI_ELAN default to
(uppercase) "M". But in Kconfig (lowercase) "m" is a magic symbol. "M"
is an ordinary symbol. As "M" is never set these Kconfig symbols will
also not be set by default.

Since I'm not aware of a reason why these driver should be set by
default, let's just drop these lines (that basically do nothing).

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.

CONFIG_USB_XHCI_HCD_DEBUGGING option is used to enable
verbose debugging output for the xHCI host controller
driver.

In the current version of the xhci-hcd driver, this

log messages to be displayed, and users may need to
recompile the linux kernel to obtain debugging
information that will help them track down problems.

This patch removes the above debug option to enable

The aim of this is to rely on the debugfs and the
dynamic debugging feature for fine-grained management
of debugging messages and to not force users to set
the debug config option and compile the linux kernel
in order to have access in that information.

This patch, also, removes the XHCI_DEBUG symbol and the

Convert PHY Drivers from menuconfig to menu so that the PHY drivers
can be explicitely selected by the controller drivers.

USB_PHY is no longer a user visible option. It is upto to the PHY
drivers to select it if needed. This patch does so for the existing
PHY drivers that use the USB_PHY library.

Doing so moves the USB_PHY and PHY driver selection problem from the
end user to the PHY and controller driver developer.

e.g.

Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select
a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver
depended on USB_PHY. Making the controller driver depend on USB_PHY
has a negative effect i.e. it becomes invisible to the user till
USB_PHY is enabled. Most end users will not familiar with this.

With this patch, the end user just needs to select the controller driver
needed for his/her platform without worrying about which PHY driver to
select.

Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend
on USB_PHY any more. They can safely select the necessary PHY drivers.

The three options USB_ARCH_HAS_{EHCI,OHCI,XHCI} are all well beyond
their recommended shelf life. They have caused numerous build failures
over the years because they are never completely correct, and with
the move to splitting out the platform specific back-ends out of the
driver, there is no real need for them any more. Also, the use of making
USB_ARCH_HAS_HCD depend on it is questionable since one can always enable
dummy_hc these days.

This patch enables them unconditionally for all platforms and
architectures, which means it is now possible to build host controller
drivers for machines that are known not to come with this hardware,
but that is just how we treat most other drivers.

In order to minimise the impact on existing architecture code and
defconfig files, all the Kconfig are left present for now. All platforms
that currently do 'select USB_ARCH_HAS_*' should subsequently be changed
not to select that. All drivers depending on USB_ARCH_HAS_HCD should
be changed to depend on USB_SUPPORT instead.

This patch splits the PCI portion of ohci-hcd out into its
own separate driver module, called ohci-pci.

The major point of difficulty lies in ohci-pci's many vendor- and
device-specific workarounds.  Some of them have to be applied before
calling ohci_start() some after, which necessitates a fair amount of
code motion.  The other platform drivers require much smaller changes.

 -no longer _creating_ CONFIG_USB_OHCI_PCI,creating CONFIG_USB_OHCI_HCD_PCI.

Just like the OHCI counter part we just can remove the architecture
specific symbols which prevent these configuration symbols from being
selected by platforms/architectures requiring it. The original
implementation did not scale at all since it required each and every
single architecture to be added for these configuration symbols to be
selected. Now it is up to the EHCI driver and/or platform to select
these configuration symbols accordingly.

This patch removes the depends on USB from all config symbols in
drivers/usb/host/Kconfig and replace that with an if USB / endif block
as suggested by Alan Stern. Some source ... Kconfig lines have been
shuffled around to permit a better regroupment of the Kconfig files
depending on "config USB" item. No functionnal change is introduced.
