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.

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

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.

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().

usb: dwc3: patches for v3.9 merge window
We're saving some extra memory now by being a lot
more conservative when allocating our event buffers.
Our default HIRD threshold value was mistakenly set
as one of the unsupported which would cause undefined
behavior. Turns out that it broke OMAP5 ES2.0, so we're
fixing it now by setting the maximum allowed HIRD
threshold (12).
Quite a few fixes to Isochronous transfers and scatter/gather
support from Pratyush.
We're also starting to support devicetree-based probe with
the latest changes from Kishon.
The usual set of cleanups also available: converting debugfs
regdump utility to regsets, better "compatible" strings for
Exynos platforms and the removal of the dependency for
Host and Gadget; now dwc3 can be compiled host-only, device-only,
and/or Dual-Role.

Currently, we enumerate devices in a slot with pci_scan_slot(), then
iterate through all the devices we found by looking for functions 0-7. But
that's wrong for ARI devices, which may have function numbers up to 255.
This means that when we hot-add an ARI device, pciehp only initializes
functions 0-7, and other functions don't work correctly. Additionally, if
we hot-remove the device, pciehp only removes functions 0-7, leaving stale
pci_dev structures for any other functions.
This patch fixes the problem by iterating over devices in a slot by using
the upstream bridge's "bus->devices" list instead.
