f7e7aa5850 USB: Add platform device support for the ISP1760 USB chip
Currently, the driver only supports PCI and PPC_OF but there are
boards like ARM RealView where this is a platform device. The patch adds
the necessary functions and registration to the isp1760-if.c file and
modifies the corresponding Makefile and Kconfig to be able to use this
driver even if PCI and PPC_OF are not enabled.

236dd4d18f USB: Driver for Freescale QUICC Engine USB Host Controller
This patch adds support for the FHCI USB controller, as found
in the Freescale MPC836x and MPC832x processors. It can support
Full or Low speed modes.

Quite a lot the hardware is doing by itself (SOF generation, CRC
generation and checking), though scheduling and retransmission is on
software's shoulders.

This controller does not integrate the root hub, so this driver also
fakes one-port hub. External hub is required to support more than
one device.

Until there is a checkbox where the user *must* select atleast one item,
and may select multiple entries I don't make it selectable anymore.
Having a driver which can't be used under any circumstances is broken
anyway and I've seen distros shipping it that way.

aa16ca307e USB: ehci: minor ISO updates, always support split ISO
Small updates to the EHCI driver's ISO support:

 - Get rid of the Kconfig option for full speed ISO.  It may
   not be perfect yet, but it hasn't appeared to be dangerous
   and pretty much every configuration wants it.

 - Instead of two places to disable an empty periodic schedule
   after an ISO transfer completes, just have one.

 - After the periodic schedule is disabled, we can short-circuit
   the schedule scan ... it can't possibly have more work to do.

Assuming a typical config with split iso enabled, the only change
in behavior should be almost unobservable:  quicker termination
of periodic scans when the schedule gets emptied.

5d3043586d USB: r8a66597-hcd: host controller driver for R8A66597
I would like to submit Renesas R8A66597 USB HCD driver.

R8A66597 is Renesas USB 2.0 host and peripheral combined
controller device originally designed for embedded products.
As a limitation of this device, it does not support externel
hub more than 2 tier, and cannot communicate with a USB
device more than 10. Then this device is not compatible with
EHCI and/or OHCI, I wrote driver support patch based on
sl811 code.

This driver has the following unique specifications:
- Implement transfer timeout to share one pipe with plural endpoint.
- Detach detection of a USB device connected to externel hub.

The driver has been tested external hub, usb-hdd, usb-cdrom,
usb-speaker, mice, keyboard, and usbtest driver.

6dbd682b7c USB: EHCI support for big-endian descriptors
This patch implements supports for EHCI controllers whose in-memory
data structures are represented in big-endian format. This is needed
(unfortunately) for the AMCC PPC440EPx SoC EHCI controller; the EHCI
spec doesn't specify little-endian format, although that's what most
other implementations use.

The guts of the patch are to introduce the hc32 type and change all
references from le32 to hc32.  All access routines are converted from
cpu_to_le32(...) to cpu_to_hc32(ehci, ...) and similar for the other
"direction".  (This is the same approach used with OHCI.)

David fixed:
	Whitespace fixes; refresh against ehci cpufreq patch; move glue
	for that PPC driver to the patch adding it; fix free symbol
	capture bugs in modified "constant" macros; and make "hc32" etc
	be "le32" unless we really need the BE options, so "sparse" can
	do some real good.

d774efeabc USB: u132-hcd: host controller driver for ELAN U132 adapter
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.

Default values for boolean and tristate options can only be 'y', 'm' or 'n'.
This patch removes wrong default for USB_ISP116X_HCD, USB_SL811_HCD and
USB_SL811_CS.

ba47f66bd9 [PATCH] improved TT scheduling for EHCI
This updates the EHCI driver by adding an improved scheduler for the
transaction translators, found in USB 2.0 hubs and used for low and
full speed devices.

 - adds periodic_tt_usecs() and some helper functions, which does
   the same thing that "periodic_usecs" does, except on the other
   side of the TT, i.e.  it calculates the low/fullspeed bandwidth
   usage instead of highspeed.

 - adds a tt_available() function which is the new implementation
   of what tt_no_collision() does ... while tt_no_collision() ensures
   that each TT handles only 1 periodic transfer at a time (a very
   pessimistic approach) this version instead tracks bandwidth and
   allows each TT to handle as many transfers as will fit on each TT's
   downstream bus (closer to best-case).

The new scheduler is selected by a config option, marked as EXPERIMENTAL
so it can be tested (and more broadly reviewed) for a while until it
seems safe to remove the original scheduler.

80cb9aee01 [PATCH] USB: EHCI for Freescale 83xx
Adding a Host Mode USB driver for the Freescale 83xx.

This driver supports both the Dual-Role (DR) controller and the
Multi-Port-Host (MPH) controller present in the Freescale MPC8349. It has
been tested with the MPC8349CDS reference system. This driver depends on
platform support code for setting up the pins on the device package in a
manner appropriate for the board in use. Note that this patch requires
selecting the EHCI controller option under the USB Host menu.

4808a1c026 [PATCH] USB: Add isp116x-hcd USB host controller driver
This patch provides an "isp116x-hcd" driver for Philips'
ISP1160/ISP1161 USB host controllers.

The driver:
 - 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.

c6de2b64eb [PATCH] USB: add sl811_cs support
This adds support for a CF-card USB Host adapter, the Ratoc REX-CFU1U, by
wrapping a PCMCIA driver around the existing "sl811-hcd" platform driver.

This CF card is especially useful for PDAs, which currently tend to have
no other solution for USB host capability.

1da177e4c3 Linux-2.6.12-rc2
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!
