Only AES use DMA in AT91SAM9G45 (TDES and SHA use PDC).
However latest Atmel TDES and SHA IP releases use DMA instead of PDC.
--> Atmel TDES and SHA drivers need DMA platform data for those IP releases.
Goal of this patch is to use the same platform data structure for all Atmel
crypto peripherals. This structure contains information about DMA interface.

Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.
- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.
- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.
- bigger driver cleanups for designware, s3c2410
- removing superfluous refcounting from drivers
- removing Ben Dooks as second maintainer due to inactivity. Thanks
for all your work so far, Ben!
- bugfixes, feature additions, devicetree fixups, simplifications...

i2c_del_mux_adapter always returns 0 and none of it current users check its
return value anyway. It is also an essential requirement of the Linux device
driver model, that functions which may be called from a device's remove callback
to free resources provided by the device, are not allowed to fail. This is the
case for i2c_del_mux_adapter(), so make its return type void to make the
fact that it won't fail explicit.

i2c_del_adapter() is usually called from a drivers remove callback. The Linux
device driver model does not allow the remove callback to fail and all resources
allocated in the probe callback need to be freed, as well as all resources which
have been provided to the rest of the kernel(for example a I2C adapter) need to
be revoked. So any function revoking such resources isn't allowed to fail
either. i2c_del_adapter() adheres to this requirement and will never fail. But
i2c_del_adapter()'s return type is int, which may cause driver authors to think
that it can fail. This led to code constructs like:
ret = i2c_del_adapter(...);
BUG_ON(ret);
Since i2c_del_adapter() always returns 0 the BUG_ON is never hit and essentially
becomes dead code, which means it can be removed. Making the return type of
i2c_del_adapter() void makes it explicit that the function will never fail and
should prevent constructs like the above from re-appearing in the kernel code.
All callers of i2c_del_adapter() have already been updated in a previous patch
to ignore the return value, so the conversion of the return type from int to
void can be done without causing any build failures.

The detach_adapter callback has been deprecated for quite some time and has no
user left. Keeping it alive blocks other cleanups, so remove it.

Tegra only supports, and always enables, device tree. Remove all ifdefs
and runtime checks for DT support from the driver. Platform data is
therefore no longer required. Delete the header that defines it.

Add i2c bus recovery infrastructure to i2c adapters as specified in the i2c
protocol Rev. 03 section 3.1.16 titled "Bus clear".
http://www.nxp.com/documents/user_manual/UM10204.pdf
Sometimes during operation i2c bus hangs and we need to give dummy clocks to
slave device to start the transfer again. Now we may have capability in the bus
controller to generate these clocks or platform may have gpio pins which can be
toggled to generate dummy clocks. This patch supports both.
This patch also adds in generic bus recovery routines gpio or scl line based
which can be used by bus controller. In addition controller driver may provide
its own version of the bus recovery routine.
This doesn't support multi-master recovery for now.

Plus I dived into lguest again, reworking the pagetable code so we can

Ugh. Annoying conflicts with the tcm_vhost -> vhost_scsi rename.
Hopefully correctly resolved.

These are specialized versions of virtqueue_add_buf(), which cover
over 80% of cases and are far clearer.
In particular, the scatterlists passed to these functions don't have
to be clean (ie. we ignore end markers).

virtio_scsi can really use this, to avoid the current hack of copying
the whole sg array. Some other things get slightly neater, too.
This causes a slowdown in virtqueue_add_buf(), which is implemented as
a wrapper. This is addressed in the next patches.

This is useful in places that recycle the same scatterlist multiple
times, and do not want to incur the cost of sg_init_table every
time in hot paths.

Add the CAIF Virtio shared memory driver for talking
to a modem.
This CAIF Link layer communicates to the modem over
shared memory. It is implemented as a virtio_driver.
The underlying virtio device is managed by the remoteproc
framework. The Virtio queue is used for transmitting data
to the modem, and the new vringh is used for receiving data.
Genalloc is used for managing the shared memory used for TX
data. The default dma-alloc-coherent allocator can only
allocate whole pages, and this wastes too much shared memory.
Flow control is implemented by stopping the TX-queues if the
virtio queues go full or we run out of memory. Queued are
reopened when queues are below the watermark.
NAPI is used in RX path, and a dedicated tasklet is used
for releasing TX buffers.

Add wrappers for the host vrings to support loose
coupling between the virtio device and driver.
A new struct vringh_config_ops with the functions
find_vrhs() and del_vrhs() is added to the virtio_device
struct. This enables virtio drivers to manage virtio
host rings without detailed knowledge of how the
vrings are created and deleted.
The function vringh_notify() is added so vringh clients
can notify the other side that buffers are added to the
used-ring.

Getting use of virtio rings correct is tricky, and a recent patch saw
an implementation of in-kernel rings (as separate from userspace).
This abstracts the business of dealing with the virtio ring layout
from the access (userspace or direct); to do this, we use function
pointers, which gcc inlines correctly.

Pull ARM SoC multiplatform updates from Olof Johansson:
"More multiplatform enablement for ARM platforms. The ones converted
in this branch are:
- bcm2835
- cns3xxx
- sirf
- nomadik
- msx
- spear
- tegra
- ux500
We're getting close to having most of them converted!
One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was
a patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then"

Merge in the clksrc/cleanup branch to avoid a silly merge conflict. For
some reason two versions of the same patch were merged in two

since it can be confusing to tell which version is the one to keep.

These patches get us closer to adding multiplatform support on
the Exynos platform, they are part of a longer series of
patches. This would get all the simple stuff out of the
way, and I don't think there is a big risk of introducing
regressions with these.
A lot of the other patches have already been merged into
subsystem trees. After this series in in arm-soc, what is
left comes down to
* The ASoC conversion to dmaengine won't make it unless someone
who knows that code better steps up to do it right away. This
means that we won't have audio in a 3.10 multiplatform kernel
on Exynos, but it will still work for users that don't enable
multiplatform.
* The irqchip (combiner), clk and clksource patches are all based
on top of other changesets we pulled in from your trees, so I
would not make them part of the next/multiplatform branch. We can
apply them on top of the next/drivers branch once they are
tested successfully.
* A trivial patch is needed in the end to actually make
CONFIG_ARCH_EXYNOS visible in multiplatform configurations.
We will do that as a separate patch once everything else is
there.

plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c
driver, so it can become a local file there and all other
inclusions removed.
plat/sdhci.h is used only to define the platform devices,
and with the exception of the platform_data structure not
needed by the driver, so we can split out the platform_data
definition instead and leave the rest to platform code.

From Stephen Warren <swarren@wwwdotorg.org>:
ARM: tegra: multi-platform conversion
This branch converts Tegra to support multi-platform/single-zImage.
One header is made accessible to drivers. The earlyprintk implementation
is moved to the multi-platform location. Some Kconfig changes are made
to enable multi-platform. Some dead files are deleted.
The APIs exposed in the now-global tegra-powergate.h should be replaced
with standard reset and power domain APIs in the future.
This branch is based on (part of) the previous soc pull request.

can still access this header file once Tegra is converted to
multiplatform, and <mach/> no longer exists.

This untangles the final bits of the prcmu code from the platform
code:
* The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c
because they are only of local significance.
* u8500_thsens_device goes into the prcmu, because it uses a PRCMU
IRQ that the platform does not see.
* IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data
because the PRCMU does not see it.

We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.
Basically we are left with the two alternatives of code
placement as:
- arch/arm/mach-ux500/pm.c - this because the code is
closely related to the GIC, and takes ownership of
some of the registers from the PRCMU related to this
PM functionality.
- drivers/mfd/db8500-prcmu-pm.c - because the code is
affecting stuff in the PRCMU register range. But then
this code needs to remap and handle GIC registers.
This patch implementation is taking the first approach.
Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.
The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.

This ensures that a function pointer passed into CLOCKSOURCE_OF_DECLARE
takes the same arguments that we use for calling that function later.
Also fix the extraneous semicolon at end of the CLOCKSOURCE_OF_DECLARE
definition.

Merge in the gic cleanup since it has a handful of annoying internal conflicts
with soc development branches. All of them are delete/delete conflicts.
* gic/cleanup:
irqchip: vic: add include of linux/irq.h
irqchip: gic: Perform the gic_secondary_init() call via CPU notifier
irqchip: gic: Call handle_bad_irq() directly
arm: Move chained_irq_(enter|exit) to a generic file
arm: Move the set_handle_irq and handle_arch_irq declarations to asm/irq.h

Remove specifying mmc controller IP version information via platform
data, instead specify device name so that driver derives it from
platform_device_id table. Also change the clock node name to match
the changed dev_id.
Tested on da850-evm to make sure driver loads without clk_get failures.

Pull ARM SoC cleanup from Olof Johansson:
"Here is a collection of cleanup patches. Among the pieces that stand
out are:
- The deletion of h720x platforms
- Split of at91 non-dt platforms to their own Kconfig file to keep
them separate
- General cleanups and refactoring of i.MX and MXS platforms
- Some restructuring of clock tables for OMAP
- Convertion of PMC driver for Tegra to dt-only
- Some renames of sunxi -> sun4i (Allwinner A10)
- ... plus a bunch of other stuff that I haven't mentioned"

This allows to remove some boilerplate code. At the same time, call the
set_handle_irq function in the initialization function of the irqchip,
so that we can remove it from the machine declaration.

Using CLKSRC_OF allows to remove the SoC specific sunxi_timer.h header,
and instead of using a custom init function in the machine definition
use the standard clocksource_of_init function.

This ensures that a function pointer passed into CLOCKSOURCE_OF_DECLARE
takes the same arguments that we use for calling that function later.
Also fix the extraneous semicolon at end of the CLOCKSOURCE_OF_DECLARE
definition.

This patch changes the name of USB ohci header from 'usb-exynos.h'
to 'usb-ohci-exynos.h'. This is because this header file has
the platdata for only EXYNOS OHCI.

git://git.linaro.org/people/shawnguo/linux-2.6 into next/cleanup
From Shawn Guo <shawn.guo@linaro.org>:
The mxs cleanup for 3.10:
* Clean up timer code and move it into drivers/clocksource
* Clean up icoll code and move it into drivers/irqchip
* Clean up clock code to not include <mach/*> headers
* Clean up rtc-stmp3xxx, mxs-lradc and mxs-saif to not include <mach/*>
headers
* Clean up mach-mxs code to get it prepared for multiplatform support

All three remaining functions declared in common.h are implemented by
clock driver. Create header include/linux/clk/mxs.h to contain them
and remove common.h.

Move icoll.c into drivers/irqchip as irq-mxs.c, and along with the
renaming, change the driver to use IRQCHIP_DECLARE.
