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

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 PHY setup code of the TI DaVinci DA8xx OHCI controller
uses ad-hoc register access using a pointer that is meant to
be used only by the DaVinci platform implementation and that
is intentionally not exported to loadable modules. This results
in a link error on configurations that use a modular OHCI
code on this platform.
While the proper solution for this problem would be to
implement a real PHY driver shared by ohci-da8xx and musb-da8xx,
this patch for now just works around the build error by
only allowing the ohci-da8xx code to be built-in.

Commit a273454341 "usb: phy: msm: Use reset framework for LINK
and PHY resets" introduced a mandatory call to reset_control_get
into the msm usb phy driver, which means we have to add a Kconfig
dependency on the API to avoid this build error:
phy/phy-msm-usb.c: In function 'msm_otg_read_dt':
phy/phy-msm-usb.c:1461:2: error: implicit declaration of function 'devm_reset_control_get' [-Werror=implicit-function-declaration]
motg->link_rst = devm_reset_control_get(&pdev->dev, "link");
^
Since the usb-ehci-msm driver currently selects the OTG driver,
we could still get a broken dependency here. To solve that,
this patch also removes the 'select', which turns out to be
unnecessary.

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.

Separate the Samsung OHCI EXYNOS host controller driver from ohci-hcd

This work is part of enabling multi-platform kernels on ARM.

Separate the W90X900(W90P910) on-chip host controller driver from
ehci-hcd host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before W90X900(W90P910)
can be booted with a multi-platform kernel
and an ehci driver that only works on one of them.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the w90X900 bus glue.
This patch is rebased on greghk/usb-next 3.12 rc1.

Hi Greg,
This pull request includes one new feature for the xhci-plat driver (device
tree support). Felipe was fine with the patch last I checked, but hadn't
provided an official Acked-by line.
This pull request also includes 13 patches from my FOSS Outreach Program for
Women (OPW) intern, Xenia. She fixed a bug in the xHCI driver so that the
driver can allocate 64-bit consistent DMA, converted the driver to use dynamic
debugging, and added a bunch of new trace events for the xHCI driver. The
python plugin for trace-cmd should be up on git hub shortly, although the trace
events are usable without it.
I'm very happy with the progress that Xenia has made, and I look forward to her
future contributions to the Linux kernel.

commit 9841f37a1c ("usb: ehci: Add support for SINGLE_STEP_SET_FEATURE
test of EHSET") added additional code to the EHCI hub driver but it is
anticipated to only have a limited audience (e.g. embedded silicon
vendors and integrators). Avoid subjecting all EHCI (and in the future
maybe xHCI/OHCI, etc.) HCD users to code bloat by conditionally
compiling the EHSET-specific additions with a new Kconfig option,
CONFIG_USB_HCD_TEST_MODE.

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
option must be turned on, in order for the debugging
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
debugging log messages at all times.
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
functions dma_to_stream_ring(), xhci_test_radix_tree()
and xhci_event_ring_work() that are not useful anymore.

All patches here have been pending on linux-usb
and sitting in linux-next for a while now.
The biggest things in this tag are:
DWC3 learned proper usage of threaded IRQ
handlers and now we spend very little time
in hardirq context.
MUSB now has proper support for BeagleBone and
Beaglebone Black.
Tegra's USB support also got quite a bit of love
and is learning to use PHY layer and generic DT
attributes.
Other than that, the usual pack of cleanups and
non-critical fixes follow.

When CONFIG_USB_SUPPORT is not selected we get things like:
scripts/kconfig/mconf Kconfig
warning: (MIPS_SEAD3 && PMC_MSP && CPU_CAVIUM_OCTEON) selects USB_EHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && USB)
It is much cleaner to make the various system Kconfigs select
USB_EHCI_BIG_ENDIAN_MMIO rather than move the system config
information into USB's Kconfig, but the warnings are annoying.
Eliminate the warning by moving the definition of
USB_EHCI_BIG_ENDIAN_MMIO outside of all the Kconfig if statements.
While we are at it move USB_OHCI_BIG_ENDIAN_DESC,
USB_OHCI_BIG_ENDIAN_MMIO, USB_OHCI_LITTLE_ENDIAN and
USB_EHCI_BIG_ENDIAN_DESC too, as they could very well suffer similar
problems for other systems.
Get rid of the redundant "default n" in USB_OHCI_BIG_ENDIAN_DESC and
USB_OHCI_BIG_ENDIAN_MMIO

FOTG210 is an OTG controller which can be configured as an
USB2.0 host. FOTG210 host is an ehci-like controller with
some differences. First, register layout of FOTG210 is
incompatible with EHCI. Furthermore, FOTG210 is lack of
siTDs which means iTDs are used for both HS and FS ISO
transfer.
