Most of this branch consists of updates, additions and general churn of
the device tree source files in the kernel (arch/arm/boot/dts). Besides
that, there are a few things to point out:
- Lots of platform conversion on OMAP2+, with removal of old board files
for various platforms.
- Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
- Some updates to pinctrl and other subsystems. Most of these are for
DT-enablement of the various platforms and acks have been collected.

The AT91 PMC (Power Management Controller) provides a USB clock used by
the different USB controllers (ehci, ohci and udc).
The atmel-ehci driver must configure the usb clock rate to 48Mhz in order
to get a fully functionnal USB host controller.
This configuration was formely done in mach-at91/clock.c, but will be
bypassed when moving to common clk framework.
This patch adds support for usb clock retrieval and configuration only if
CCF is enabled (CONFIG_COMMON_CLK).

The only notification supported by the Device Management class is
Response Available. But this driver is also used as a subdriver of
other CDC classes, allowing notifications like Speed Change and
Network Connection. This results in log messages which are only
confusing to an end user:
[66255.801874] cdc_mbim 1-3:1.5: unknown notification 42 received: index 5 len 8
These drivers use cdc-wdm as a subdriver to allow access to an
embedded management protocol, and all management is expected to
use this protocol. There is therefore no need to handle any of
these optional CDC notifications. Instead we can let the cdc-wdm
driver recognize them and log a debug level message instead of an
error.

Final conversions to configfs for mass storage, acm_ms, and

MUSB should now work out of the box on AM335x-based boards
(beagle bone white and black) with DMA thanks to Sebastian's
work.
We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/
by selecting CONFIG_USB_GADGET_VERBOSE.
s3c-hsotg got quite a few non-critical fixes but also learned
a few new tricks (isochronous transfers, multi count support).
The Marvel USB3 Controller driver got a memory leak fix.
devm_usb_get_phy() learned not to return NULL, ever.
Other than these patches, we have the usual set of cleanups
ranging from removal of unnecessary *_set_drvdata() to using
SIMPLE_DEV_PM_OPS.

usb: patches for v3.13
Final conversions to configfs for mass storage, acm_ms, and
multi gadgets.
MUSB should now work out of the box on AM335x-based boards
(beagle bone white and black) with DMA thanks to Sebastian's
work.
We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/
by selecting CONFIG_USB_GADGET_VERBOSE.
s3c-hsotg got quite a few non-critical fixes but also learned
a few new tricks (isochronous transfers, multi count support).
The Marvel USB3 Controller driver got a memory leak fix.
devm_usb_get_phy() learned not to return NULL, ever.
Other than these patches, we have the usual set of cleanups
ranging from removal of unnecessary *_set_drvdata() to using
SIMPLE_DEV_PM_OPS.

cbaf_probe() does cbaf->usb_dev = usb_get_dev(interface_to_usbdev(iface)),
but there is no usb_put_dev() anywhere in cbaf.
The patch adds usb_put_dev() to cbaf_disconnect() and to an error path in cbaf_probe().
Also it adds missed usb_put_intf(iface) to the error path.

hcd-pci.c in usbcore contains a check for wakeup requests racing with
controller suspend. This check is going to be moved out of usbcore
and into the individual controller drivers, where it can apply to all
platforms, not just PCI.
This patch adds the check to uhci-hcd. Ironically, none of the
non-PCI platform drivers for uhci-hcd implement suspend/resume.
Nevertheless, this change is needed to accomodate the upcoming change
to usbcore.
The patch also removes an outdated check of the root hub state. For
one thing, the PM layer has long been quite reliable about suspending
root hubs before controllers. For another, virtually the same check
is also made in hcd-pci.c; there's no point in repeating it.

This patch changes a dev_warn() call in usbcore to dev_dbg(). It's

This patch fixes several sparse errors in ehci-hcd introduced by

This patch fixes a type mismatch in ehci-hcd caused by commit
b35c5009bb (USB: EHCI: create per-TT bandwidth tables). The c_maskp
parameter in check_intr_schedule() was changed to point to unsigned
int rather than __hc32, but the prototype declaration wasn't adjusted
accordingly.

Hi Greg,
Here's my pull request for usb-next and 3.13. My xHCI tree is closed
after this point, since I won't be able to run my full tests while I'm in
Scotland. After Kernel Summit, I'll be on vacation with access to email
from Oct 26th to Nov 6th.
Here's what's in this request:
- Patches to fix USB 2.0 Link PM issues that cause USB 3.0 devices to not
enumerate or misbehave when plugged into a USB 2.0 port. Those are
marked for stable.
- A msec vs jiffies bug fix by xiao jin, which results in fairly harmless
behavior, and thus isn't marked for stable.
- Xenia's patches to refactor the xHCI command handling code, which makes
it much more readable and consistent.
- Misc cleanup patches, one by Sachin Kamat and three from Dan Williams.
Here's what's not in this request:
- Dan's two patches to allow the xHCI host to use the "Windows" or "new"
enumeration scheme. I did not have time to test those, and I want to
run them with as many USB devices as I can get a hold of. That will
have to wait for 3.14.
- Xenia's patches to remove xhci_readl in favor of readl. I'll queue
those for 3.14 after I test them.
- The xHCI streams update, UAS fixes, and usbfs streams support. I'm not
comfortable with changes and fixes to that patchset coming in this late.
I would rather wait for 3.14 and be really sure the streams support is
stable before we add new userspace API and remove CONFIG_BROKEN from the
uas driver.
- Julius' patch to clear the port reset bit on hub resume that came in
a couple days ago. It looks harmless, but I would rather take the time
to test and queue it for usb-linus and the stable trees once 3.13-rc1
is out.

Do not overwrite the multi-byte fields of usb_wa_descriptor with their
cpu format values after reading the descriptor. Leave the values as
__le16 and swap on use. This is more consistent with other uses of USB
descriptors.

This patch serializes access to the HWA data transfer out (DTO)
endpoint. This prevents a situation where two transfer requests being
sent concurrently to separate downstream endpoints could interleave
their transfer request and transfer data packets causing data
corruption. The transfer processing code will now attempt to acquire
the DTO resource before sending a transfer to the HWA. If it cannot
acquire the resource, the RPIPE that the transfer is assigned to will
be placed on a waiting list. When the DTO resource is released, the
actor releasing the resource will serivce the RPIPEs that are waiting.

If everything (musb, cppi41, phy) is built-in then musb will start
without the dma engine printing only
|musb-hdrc musb-hdrc.0.auto: Falied to request rx1.
The reason for this is that the musb device structs are created & probed
before those of the cppi41 device. So the cppi41 device is probed too
late.
As a workaround for this allow the musb_cppi41 part to defer the probe
if everything is fine except for the missing DMA controller. In case of
another error we continue.

In commit f3ce4d5 ("usb: musb: core: call dma_controller_destroy() in the err path")
I erroneously assumed that the dma controller is not removed in the
error patch. This was wrong because it happens later via musb_free().
That means the original commit can be reverted because it is wrong or we
do this, so it is more obvious.
