Separate the  Samsung S5P/EXYNOS 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 S5P/EXYNOS can
be booted with a multi-platform kernel. We currently expect those
to get merged for 3.10.

With the infrastructure added by Alan Stern in patch 3e023203
"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 s5p bus glue.

In V4 (arnd)
 - revert some of the pointless changes.
 - fix allocation of s5p specific data structure.

In V3:
 - Detailed commit message added here, why this patch is required.
 - MODULE_LICENSE is GPL v2.
 - Added .extra_priv_size to eliminate the separate allocation of
   the s5p_ehci_hcd structure and removed .reset function pointer
   initialization.
 - Arranged  #include's in alphabetical order.
 - After using extra_priv_size initialization, struct usb_hcd *hcd
   is redundant and can be removed from the probe function.
 - Eliminated s5p_ehci_phy_enable,contents of statements moved
   into the s5p_ehci_probe
 - Eliminated s5p_ehci_phy_disable, contents of statements moved into

Separate the SPEAr 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 SPEAr can be
booted with a multi-platform kernel, but they are queued in the
arm-soc tree for 3.10.

"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate

In V4 (arnd):
 - renamed all 'struct spear_ehci' pointers from 'ehci' to the
   less ambiguous 'sehci'.
 - folded trivial spear_start_ehci/spear_stop_ehci functions into
   callers.
 - brought back initialization of ehci->caps.

In V3:
 - Detailed commit message added here about why this patch is required.
 - Eliminated ehci_spear_setup routine because hcd registers can
   be directly set in the spear_ehci_hcd_drv_probe function.
 - spear_overrides struct initialized.
 - Converted to using .extra_priv_size for allocating spear_ehci,
   and updated all users of that structure.
 - to_spear_ehci() macro modified for spear_ehci.

In V2:
 - Replaced spear as SPEAr everywhere, leaving functions/variables/config options.

The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus.  This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.

The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.

The ehci and ohci blocks share a common clocking and PHY
infrastructure.  Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.

Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in

This "u132-hcd" module is one half of the "driver" for
ELAN's U132 which is a USB to CardBus OHCI controller
adapter. This module needs the "ftdi-elan" module in
order to communicate to CardBus OHCI controller inserted
into the U132 adapter.

When the "ftdi-elan" module detects a supported CardBus
OHCI controller in the U132 adapter it loads this "u132-hcd"
module.

Upon a successful device probe() the single workqueue
is started up which does all the processing of commands
from the USB core that implement the host controller.

The workqueue maintains the urb queues and issues commands
via the functions exported by the "ftdi-elan" module. Each
such command will result in a callback.

Note that the "ftdi-elan" module is a USB client driver.

Note that this "u132-hcd" module is a (cut-down OHCI)
host controller.

Thus we have a topology with the parent of a host controller
being a USB client! This really stresses the USB subsystem
semaphore/mutex handling in the module removal.

(a) merge these copies with the originals in the HCD reset methods.
they don't wholly agree, despite doing the very same thing; and

(b) eventually change it so "usb-handoff" is the default, to help

 - is relatively small, meant for use on embedded platforms.
 - runs usbtests 1-14 without problems for days.
 - has been in use by 6-7 different people on ARM and PPC platforms,
   running a range of devices including USB hubs.
 - supports suspend/resume of both the platform device and the root hub;
   supports remote wakeup of the root hub (but NOT the platform device)
   by USB devices.
 - does NOT support ISO transfers (nobody has asked for them).
 - is PIO-only.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
