This patch (as1656) adds a module parameter to the net2280 UDC driver
to force full-speed operation. It is intended for testing purposes,
where one wants to check how well a full-speed device performs when
attached to a high-speed bus. Without this parameter it would be
necessary to interpose a full-speed hub; otherwise the net2280 would
connect at high speed.

The usbtest driver includes some rather simple-minded logic for
selecting an altsetting to test. It doesn't work well for the g_zero
gadget, because it selects altsetting 0 (which doesn't have
isochronous endpoints) rather than altsetting 1 (which does have them,
if the gadget's hardware supports them). This prevents usbtest's
isochronous tests (15, 16, 22, and 23) from working with g_zero.
Since g_zero is one of the most common gadget drivers used for USB
testing, usbtest should do a better job of supporting it. But since
some programs may rely on the current scheme for selecting
altsettings, I didn't want to change it.
Instead, this patch (as1655) adds a module parameter to usbtest, which
can be used to override the default altsetting. Since usbtest is
never used by normal users (most distributions probably don't even
build it), the new module parameter won't inconvenience anybody. In
any case, it is entirely optional -- leaving it unset preserves the
existing behavior.
The patch also fixes a related bug in usbtest: After selecting an
altsetting, the driver neglects to store its selection.

This reverts commit 88bb965ed711e8a5984e70208ebc901a6ff4141f.
The linux-next branch of linux-pm tree has replaced
acpi_power_resource_(un)register_device() with new routines.
Commit 88bb965 will cause conflict in the linux-next tree.
So revert it and this will not affect other functions. Will
send a new patch with new routines after 3.9 merge window.

This patch is to set power.async_suspend for usb port in order
to allow it to be suspended and resumed asynchronously during
system sleep transitions.
The power.async_suspend flag is also set for devices that don't have
suspend or resume callbacks, because otherwise they would make the
main suspend/resume thread wait for their "asynchronous" children
(during suspend) or parents (during resume), effectively negating the
possible gains from executing these devices' suspend and resume
callbacks asynchronously.

This patch is to add usb port auto power off mechanism.
When usb device is suspending, usb core will suspend usb port and
usb port runtime pm callback will clear PORT_POWER feature to
power off port if all conditions were met. These conditions are
remote wakeup disable, pm qos NO_POWER_OFF flag clear and persist
enable. When it resumes, power on port again.
Add did_runtime_put in the struct usb_port to ensure
pm_runtime_get/put(portdev) to be called pairedly. Set did_runtime_put
to true when call pm_runtime_put(portdev) during suspending. The
pm_runtime_get(portdev) only will be called when did_runtime_put
is set to true during resuming. Set did_runtime_put to false after
calling pm_runtime_get(portdev).
Make clear_port_feature() and hdev_to_hub() as global symbol.
Rename clear_port_feature() to usb_clear_port_feature() and
hdev_to_hub() to usb_hub_to_struct_hub().
Extend hub_port_debounce() with the fuction of debouncing to
be connected. Add two wraps: hub_port_debounce_be_connected()
and hub_port_debouce_be_stable().
Increase HUB_DEBOUNCE_TIMEOUT to 2000 because some usb ssds
needs around 1.5 or more to make the hub port status to be
connected steadily after being powered off and powered on.

usb: xceiv: patches for v3.9 merge window
Two new PHY drivers coming here: one for Samsung,
one for OMAP. Both architectures are adding USB3
support to mainline kernel.
The PHY layer now allows us to have mulitple PHYs
of the same type, which is necessary for platforms
which provide more than one USB peripheral port.
There's also a few cleanups here: removal of __dev*
annotations, conversion of a cast to to_delayed_work(),
and mxs-phy learns about ->set_suspend.

In order to add support for multipe PHY's of the same type, new API's
for adding PHY and getting PHY has been added. Now the binding
information for the PHY and controller should be done in platform file
using usb_bind_phy API. And for getting a PHY, the device pointer of the
USB controller and an index should be passed. Based on the binding
information that is added in the platform file, usb_get_phy_dev will return the
appropriate PHY.
Already existing API's to add and get phy by type is not removed. These
API's are deprecated and will be removed once all the platforms start to
use the new API.

In order to support platforms which has multiple PHY's (of same type) and
which has multiple USB controllers, a new design is adopted wherin the binding
information (between the PHY and the USB controller) should be passed to the
PHY library from platform specific file (board file).
So added a new API to pass the binding information.

Directly casting a work_struct pointer to a delayed_work is risky if the
work member of struct delayed_work is ever moved from being the first
member.
Instead, use the inline function to_delayed_work(), which does the same
cast in a safer way (using container_of).

Felipe writes:
usb: gadget: patches for v3.9 merge window
finally getting rid of the old ->start()/->stop() methods
in favor of the better and improved ->udc_start()/->udc_stop().
There were surprisingly quite a few users left, but all of them
have been converted.
f_mass_storage removed some dead code, which is always great ;-)
There's also a big cleanup to the gadget framework from Sebastian
which gets us a lot closer to having only function drivers in
kernel and move over to configfs-based binding.
Other than these, there's the usual set of cleanups: s3c UDCs are
moving over to devm_regulator_bulk_get() API, at91_udc removed
an unnecessary check for work_pending() before scheduling and
there's the removal of an unused variable from uac2_pcm_trigger().

usally we will use udc->tranceiver == NULL or
udc->tranceiver != NULL.
So when failed to get the udc->tranceiver by usb_get_phy(), we
directly set udc->tranceiver to be NULL.
Then the source code will not need macro IS_ERR_OR_NULL() for
udc->tranceiver judgement. It can reduce the line size and make
the judgement simple.

Those have been deprecated for a long time and
previous patches just converted all remaining
users of those.
Since there are no in-tree users and we don't
want any new users for them, let's obliterate
every piece of code related to those calls.
