Pull ARM driver updates from Olof Johansson:
"Updates of SoC-near drivers and other driver updates that makes more
sense to take through our tree.
The largest part of this is a conversion of device registration for
some renesas shmobile/sh devices over to use resources. This has
required coordination with the corresponding arch/sh changes, and
we've agreed to merge the arch/sh changes through our tree.
Added in this branch is support for Trusted Foundations secure
firmware, which is what is used on many of the commercial Nvidia Tegra
products that are in the market, including the Nvidia Shield. The
code is local to arch/arm at this time since it's uncertain whether it
will be shared with arm64 longer-term, if needed we will refactor
later.
A couple of new RTC drivers used on ARM boards, merged through our
tree on request by the RTC maintainer.
... plus a bunch of smaller updates across the board, gpio conversions
for davinci, etc"

Pull ARM SoC cleanups from Olof Johansson:
"This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep
it strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared
with Mike Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.

According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB
register error issue", All USB register write operations must
use the ARM SWP instruction. So, we implement a special ehci_write
for imx28.
Discussion for it at below:
http://marc.info/?l=linux-usb&m=137996395529294&w=2
Without this patcheset, imx28 works unstable at high AHB bus loading.
If the bus loading is not high, the imx28 usb can work well at the most
of time. There is a IC errata for this problem, usually, we consider
IC errata is a problem not a new feature, and this workaround is needed
for that, so we need to add them to stable tree 3.11+.

Commit 35773dac5f862cb1c82ea151eba3e2f6de51ec3e "usb: xhci: Link TRB
must not occur within a USB payload burst" attempted to fix an issue
found with USB ethernet adapters, and inadvertently broke USB storage
devices. The patch attempts to ensure that transfers never span a
segment, and rejects transfers that have more than 63 entries (or
possibly less, if some entries cross 64KB boundaries).
usb-storage limits the maximum transfer size to 120K, and we had assumed
the block layer would pass a scatter-gather list of 4K entries,
resulting in no more than 31 sglist entries:
http://marc.info/?l=linux-usb&m=138498190419312&w=2
That assumption was wrong, since we've seen the driver reject a write
that was 218 sectors long (of probably 512 bytes each):
Jan 1 07:04:49 jidanni5 kernel: [ 559.624704] xhci_hcd 0000:00:14.0: Too many fragments 79, max 63

Limit the number of scatter-gather entries to half a ring segment. That
should be margin enough in case some entries cross 64KB boundaries.
Increase the number of TRBs per segment from 64 to 256, which should
result in ring segments fitting on a 4K page.

Currently prepare_ring() returns -ENOMEM if the urb won't fit into a
single ring segment. usb_sg_wait() treats this error as a temporary
condition and will keep retrying until something else goes wrong.
The number of retries should be limited in usb_sg_wait(), but also
prepare_ring() should not return an error code that suggests it might
be worth retrying. Change it to -EINVAL.

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/cleanup
From Stephen Warren:
ARM: tegra: implement common DMA and resets DT bindings
This series converts the Tegra DTs and drivers to use the common/
standard DMA and reset bindings, rather than custom bindings. It also
adds complete documentation for the Tegra clock bindings without
actually changing any binding definitions.
This conversion relies on a few sets of patches in branches from outside
the Tegra tree:
1) A patch to add an DMA channel request API which allows deferred probe
to be implemented.
2) A patch to implement a common part of the of_xlate function for DMA
controllers.
3) Some ASoC patches (which in turn rely on (1) above), which support
deferred probe during DMA channel allocation.
4) The Tegra clock driver changes for 3.14.
Consequently, this branch is based on a merge of all of those external
branches.
In turn, this branch is or will be pulled into a few places that either
rely on features introduced here, or would otherwise conflict with the
patches:
a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
conflicts.
b) The DRM tree, which introduces new code that relies on the reset
controller framework introduced in this branch, and to avoid
conflicts.

git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next
Sarah writes:
xhci: Cleanups, non-urgent fixes for 3.14.
Happy Holidays, Greg!
Here's four patches to be queued to usb-next for 3.14.
One adds a module parameter to the xHCI driver to allow users to enable
xHCI quirks without recompiling their kernel, which you've already said
is fine. The second patch is a bug fix for new usbtest code that's only
in usb-next. The third patch is simple cleanup.
The last patch is a non-urgent bug fix for xHCI platform devices. The
bug has been in the code since 3.9. You've been asking me to hold off
on non-urgent bug fixes after -rc4/-rc5, so it can go into usb-next, and
be backported to stable once 3.14 is out.
These have all been tested over the past week. I did run across one
oops, but it turned out to be a bug in 3.12, and therefore not related
to any of these patches.
Please queue these for usb-next and 3.14.
Thanks,
Sarah Sharp

If CONFIG_PCI is enabled, make sure xhci_cleanup_msix()
doesn't try to free a bogus PCI IRQ or dereference an invalid
pci_dev when the xHCI device is actually a platform_device.
This patch should be backported to kernels as old as 3.9, that
contain the commit 52fb61250a7a132b0cfb9f4a1060a1f3c49e5a25

Change the default enumeration scheme for xhci attached non-SuperSpeed
devices from:
Reset
SetAddress [xhci address-device BSR = 0]
GetDescriptor(8)
GetDescriptor(18)
...to:
Reset
[xhci address-device BSR = 1]
GetDescriptor(64)
Reset
SetAddress [xhci address-device BSR = 0]
GetDescriptor(18)
...as some devices misbehave when encountering a SetAddress command
prior to GetDescriptor. There are known legacy devices that require
this scheme, but testing has found at least one USB3 device that fails
enumeration when presented with this ordering. For now, follow the ehci
case and enable 'new scheme' by default for non-SuperSpeed devices.
To support this enumeration scheme on xhci the AddressDevice operation
needs to be performed twice. The first instance of the command enables
the HC's device and slot context info for the device, but omits sending
the device a SetAddress command (BSR == block set address request).
Then, after GetDescriptor completes, follow up with the full
AddressDevice+SetAddress operation.
As mentioned before, this ordering of events with USB3 devices causes an
extra state transition to be exposed to xhci. Previously USB3 devices
would transition directly from 'enabled' to 'addressed' and never need
to underrun responses to 'get descriptor'. We do see the 64-byte
descriptor fetch the correct data, but the following 18-byte descriptor
read after the reset gets:
bLength = 0
bDescriptorType = 0
bcdUSB = 0
bDeviceClass = 0
bDeviceSubClass = 0
bDeviceProtocol = 0
bMaxPacketSize0 = 9
instead of:
bLength = 12
bDescriptorType = 1
bcdUSB = 300
bDeviceClass = 0
bDeviceSubClass = 0
bDeviceProtocol = 0
bMaxPacketSize0 = 9
which results in the discovery process looping until falling back to
'old scheme' enumeration.

We've got regression reports that my previous fix for spurious wakeups
after S5 on HP Haswell machines leads to the automatic reboot at
shutdown on some machines. It turned out that the fix for one side
triggers another BIOS bug in other side. So, it's exclusive.
Since the original S5 wakeups have been confirmed only on HP machines,
it'd be safer to apply it only to limited machines. As a wild guess,
limiting to machines with HP PCI SSID should suffice.
This patch should be backported to kernels as old as 3.12, that
contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix

Suspend scenario in case of ohci-spear glue was not
properly handled as it was not suspending generic part
of ohci controller. Alan Stern suggested, properly handle
ohci-spear suspend scenario.
Calling explicitly the ohci_suspend() routine in
spear_ohci_hcd_drv_suspend() will ensure proper
handling of suspend scenario.
