Pull PCI changes (including maintainer change) from Jesse Barnes:
"This pull has some good cleanups from Bjorn and Yinghai, as well as
some more code from Yinghai to better handle resource re-allocation
when enabled.
There's also a new initcall_debug feature from Arjan which will print
out quirk timing information to help identify slow quirks for fixing
or refinement (Yinghai sent in a few patches to do just that once the
new debug code landed).
Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
He's been a core PCI and Linux contributor for some time now, and has
kindly volunteered to take over. I just don't feel I have the time
for PCI review and work that it deserves lately (I've taken on some
other projects), and haven't been as responsive lately as I'd like, so
I approached Bjorn asking if he'd like to manage things. He's going
to give it a try, and I'm confident he'll do at least as well as I
have in keeping the tree managed, patches flowing, and keeping things
stable."

This driver can be used as a subdriver of another USB driver, allowing
it to export a Device Managment interface consisting of a single interrupt
endpoint with no dedicated USB interface.
Some devices provide a Device Management function combined with a wwan
function in a single USB interface having three endpoints (bulk in/out
+ interrupt). If the interrupt endpoint is used exclusively for DM
notifications, then this driver can support that as a subdriver
provided that the wwan driver calls the appropriate entry points on
probe, suspend, resume, pre_reset, post_reset and disconnect.
The main driver must have full control over all interface related
settings, including the needs_remote_wakeup flag. A manage_power
function must be provided by the main driver.
A manage_power stub doing direct flag manipulation is used in normal

The kernel doc entry for usb_unlink_urb() contains the phrase "This
request is always asynchronous.". The "always" leads to the assumption
that the ->complete() callback is not called from within
usb_unlink_urb(). This is not true. The HCD is allowed to call the
->complete() from within ->urb_dequeue() if it is appropriate for the
hardware.
This patch updates the kernel doc so usb-device driver authors make sure
to drop all locks (and make sure it is okay to drop them) which are
acquired by the complete callback before calling usb_unlink_urb().

This patch updates the cp210x driver to support CP210x multiple
interface devices devices from Silicon Labs. The existing driver
always sends control requests to interface 0, which is hardcoded in
the usb_control_msg function calls. This only allows for single
interface devices to be used, and causes a bug when using ports on an
interface other than 0 in the multiple interface devices.
Here are the changes included in this patch:
- Updated the device list to contain the Silicon Labs factory default
VID/PID for multiple interface CP210x devices
- Created a cp210x_port_private struct created for each port on
startup, this struct holds the interface number
- Added a cp210x_release function to clean up the cp210x_port_private
memory created on startup
- Modified usb_get_config and usb_set_config to get a pointer to the
cp210x_port_private struct, and use the interface number there in the
usb_control_message wIndex param

dwc3_gadget_ep_set_wedge() and dwc3_gadget_set_selfpowered() were
modifying dwc->flags/dwc->is_selfpowered without taking the lock.
Since those modifications are non-atomic, that could cause other
flags to be corrupted. Fix them both to take the lock.

The loop in dwc3_gadget_set_link_state() was using a udelay(500),
which is a long time to delay in interrupt context. Change it to
udelay(5) and increase the loop count to match.

For am5536udc we have just simple coding style fixes. Nothing that has any
potential to cause any issues going forward.
With mv_udc, there's only one single change removing an unneeded NULL check.
at91_udc also only saw a single change this merge window, and that's only
removing a duplicated header.
The Renesas controller has a few more involved changes. Support for SUDMAC was
added, there's now a special handling of IRQ resources for when the IRQ line is
shared between Renesas controller and SUDMAC, we also had a bug fix where
Renesas controller would sleep in atomic context while doing DMA transfers from
a tasklet. There were also a set of minor cleanups.
The FSL UDC also had a scheduling in atomic context bug fix, but that's all.
Thanks to Sebastian, the dummy_hcd now works better than ever with support for
scatterlists and streams. Sebastian also added SuperSpeed descriptors to the
serial gadgets.
The highlight on this merge is the addition of a generic API for mapping and
unmapping usb_requests. This will avoid code duplication on all UDC controllers
and also kills all the defines for DMA_ADDR_INVALID which UDC controllers
sprinkled around. A few of the UDC controllers were already converted to use
this new API.

a patch making modules behave better, there's a fix on debugfs'
error path, a small change removing an unnecessary pm_runtime
call on musb_shutdown() and a fix to relesect the endpoint in
Interrupt context.
This last patch is needed because we must drop musb's lock when
calling request->complete() and that could cause problems if another
thread queues a request and ends up changing MUSB_INDEX register.

This is the first cut at a driver for the Fintek F81232 USB to serial
single port converter. This provides the initial framework for the
device, and some data can move through it, but no line settings are
handled, so it's not that useful yet. It does give people a starting
place to work from.
Thank to Fintek for providing samples and specifications, without which,
this driver would have never been able to be written.

Now that Alan Stern has cleaned up the usb serial driver registration,
we have the ability to create a module_usb_serial_driver macro to make
things a bit simpler, like the other *_driver macros created.
But, as we need two functions here, we can't reuse the existing
module_driver() macro, so we need to roll our own.
Here's a patch implementing module_usb_serial_driver() and it converts
the pl2303 driver to use it, showing a nice cleanup.

US_BULK_FLAG_IN is defined as 1 and not used. The USB storage spec says
that bit 7 of flags within CBW defines the data direction. 1 is DATA-IN
(read from device) and 0 is the DATA-OUT. Bit 6 is obselete and bits 0-5
are reserved.
This patch redefines the unsued define US_BULK_FLAG_IN from 1 to 1 << 7
aka 0x80 and replaces the obvious users. In a following patch the
storage gadget will use it as well.

drivers/usb/core/hcd-pci.c:438:12: warning: 'resume_common' defined but not used
As per above, the functions are only used if RUNTIME/SLEEP are set,
so make the two functions conditional on these Kconfig values.

those routines have everything we need to map/unmap
USB requests and it's better to use them.
In order to achieve that, we had to add a simple
change on how we allocate and use our setup buffer;
we cannot allocate it from coherent anymore otherwise
the generic map/unmap routines won't be able to easily
know that the GetStatus request already has a DMA
address.

It has discussed at: http://www.spinics.net/lists/linux-usb/msg57302.html
For PowerPC, there is dma_mask at struct pdev_archdata, but there is
no dma_mask at struct pdev_archdata for ARM. The pdev_archdata is
related to specific platform, it should NOT be accessed by
cross platform drivers, like USB.
The code for pdev_archdata should be useless, as for PowerPC,
it has already gotten the value for pdev->dev.dma_mask at function
arch_setup_pdev_archdata of arch/powerpc/kernel/setup-common.c.
