bae4bd848d [PATCH] USB: add support for AT91 gadget
This adds support for the USB peripheral controller on AT91
(rm9200, eventually also sam9261 or uClinux) platforms.

More SOC support for Linux-USB ... an uncomplicated pure PIO driver.
It'd be worth using this as a model, if you're starting a driver
for some other peripheral controller.

39a269c09f [PATCH] USB: add support for OCHI on AT91rm9200
This adds support for OHCI on AT91rm9200 based boards.

Possibly of interest here is the way this uses <linux/clk.h> to
gate clocks on/off during system pm state transitions.  That's
typical for non-PCI systems.  Some can go further; Mini-A host
side connectors enable ID-pin sensing.

d085229938 [PATCH] USB: EHCI unlink tweaks
This patch modifies the behavior of the EHCI driver in an unlink path
that seems to be causing various issues on some systems.  Those problems
have included issues with disconnection, driver unbinding, and similar
cases where urb unlinking would just not work right.

This patch should help avoid those problems by not turning off the async
(control/bulk) schedule until it's not expecting an "async advance" IRQ,
which comes from the processing passing the schedule head.  Whether the
driver attempts to do such things is dependent on system timings, so
many folk would never have seen these problems.

8cd42e97bf [PATCH] USB: EHCI and Freescale 83xx quirk
On the MPC834x processors the multiport host (MPH) EHCI controller has an
erratum in which the port number in the queue head expects to be 0..N-1
instead of 1..N.  If we are on one of these chips we subtract one from
the port number before putting it into the queue head.

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.

469d02293d [PATCH] USB: EHCI full speed ISO bugfixes
This patch replaces the split ISO raw_mask calculation code in the
iso_stream_init() function that computed incorrect numbers of high
speed transactions for both input and output transfers.

In the output case, it added a superfluous start-split transaction for
all maxmimum packet sizes that are a multiple of 188.

In the input case, it forgot to add complete-split transactions for all
microframes covered by the full speed transaction, and the additional
complete-split transaction needed for the case when full speed data
starts arriving near the end of a microframe.

These changes don't affect the lack of full speed bandwidth, but at
least it removes the MMF errors that the HC raised with some input
streams.

f8aeb3bb86 [PATCH] USB: EHCI and NF2 quirk
This teaches the EHCI driver about a quirk seen in older NForce2 chips,
adding a workaround to ignore selective suspend requests.  Bus-wide
(so-called "global") suspend still works, as does USB wakeup of a
root hub that's globally suspended.

There's still a hole in this support though.  Strictly speaking, this
should _fail_ selective suspend requests, rather than ignoring them,
since doing it this way means that devices which should be able to issue
remote wakeup are not going to be able to do that.  For now, we'll just
live with that problem ... since usbcore expects to do selective suspend
on the way towards a full bus suspend, and usbcore needs to be able to
do full bus suspend.
