Linus Walleij d47cbd5bce crypto: ux500 - add missing comma
Commit 4f31f5b19e
"PM / crypto / ux500: Use struct dev_pm_ops for power management"
add a new line to the driver struct but missed to add a
trailing comma, causing build errors when crypto is
selected. This adds the missing comma.

This was not noticed until now because the crypto block
is not in the ux500 defconfig. A separate patch will
be submitted to fix this.

This reverts commit 891104ed00.

Current IPsec ESN implementation for authencesn(cbc(aes), hmac(sha))
(separate encryption and integrity algorithms) does not conform
to RFC4303.

ICV is generated by hashing the sequence
SPI, SeqNum-High, SeqNum-Low, IV, Payload
instead of

Mark A. Greer f9fb69e73c crypto: omap-aes - Add CTR algorithm Support
The OMAP3 and OMAP4/AM33xx versions of the AES crypto
module support the CTR algorithm in addition to ECB
and CBC that the OMAP2 version of the module supports.

So, OMAP2 and OMAP3 share a common register set but
OMAP3 supports CTR while OMAP2 doesn't.  OMAP4/AM33XX
uses a different register set from OMAP2/OMAP3 and
also supports CTR.

To add this support, use the platform_data introduced
in an ealier commit to hold the list of algorithms
supported by the current module.  The probe routine
will use that list to register the correct algorithms.

Note: The code being integrated is from the TI AM33xx SDK
and was written by Greg Turner <gkmturner@gmail.com> and
Herman Schuurman (current email unknown) while at TI.

Julia Lawall 17bebdcd5c crypto: bfin_crc - reposition free_irq to avoid access to invalid data
The data referenced by an interrupt handler should not be freed before the
interrupt is ended.  The handler is bfin_crypto_crc_handler.  It may refer
to crc->regs, which is released by the iounmap.

Furthermore, the second argument to all calls to free_irq is incorrect.  It
should be the same as the last argument of request_irq, which is crc,
rather than crc->dev.

Tony Lindgren a62a6e98c3 ARM: OMAP2+: Disable code that currently does not work with multiplaform
We still need to fix up few places for multiplatform support,
but that can proceed separately. Fix the issue by making the
problem drivers depends !ARCH_MULTIPLATFORM for now.

The remaining pieces that are not multiplatform compatible
for omap2+ SoCs are:

1. Some drivers are using custom omap_dm_timer calls

There are two drivers that are directly usign omap hardware
timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
drivers/staging/tidspbridge/core/dsp-clock.c. These can be
fixed for multiplatform by allowing a minimal set of hardware
timers to be accessed, and for some functionality by using the
hrtimer framework.

2. Hardware OMAP4_ERRATA_I688 needs to be fixed up

This can't be enabled for multiplatform configurations in
it's current form. It may be possible to fix it up to do
instruction replacement early on during init. Luckily it
looks like this errata does not seem to get hit with
mainline kernel code alone at least currently.

3. Legacy header needed for omap-sham.c

Looks like it still needs mach/irqs.h for omap1 that
does not exist for multiplatform systems. Just ifdef
it for now.

4. Mailbox is waiting to get moved to drivers

Disable it for now to avoid adding a dependency to the
mailbox patches.

Linus Torvalds a11da7df65 ARM: arm-soc: power management and clock changes
This branch contains a largeish set of updates of power management and
 clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a
 few around hotplug/suspend/resume on Exynos.
 
 It includes a split-up of some of the OMAP clock data into separate
 files which adds to the diffstat, but gross delta is fairly reasonable.

Tony Lindgren 45c3eb7d3a ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h
Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.

Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.

So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.

The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.

Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.

Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.

Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.

Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

Olof Johansson 46e8a79eb5 ARM: tegra: single-zImage preparation work
Various cleanups and enhancements are made to core Tegra code towards the
 aim of including Tegra in a multi-platform ARM kernel:
 
 RTC, timer, and TWD are configured via device tree.
 
 SPARSE_IRQ is enabled.
 
 Tegra's debug_ll options are simplified, and the macros brought into
 line with other multi-platform implementations, and moved to the new
 common location.
 
 Two headers still need to be eliminated in order to include Tegra in a
 multi-platform kernel/ <mach/{clk,powergate}.h>. A new common API needs
 to be invented to replace parts of clk.h. powergate.h might be replaced
 by regulators; this needs more investigation.
 
 This pull request is based on tegra-for-3.8-dt, followed by a merge of
 arm-soc's devel/debug_ll_init branch.

Merge tag 'tegra-for-3.8-single-zimage' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/multiplatform

From Stephen Warren:
ARM: tegra: single-zImage preparation work

Various cleanups and enhancements are made to core Tegra code towards the
aim of including Tegra in a multi-platform ARM kernel:

RTC, timer, and TWD are configured via device tree.

SPARSE_IRQ is enabled.

Tegra's debug_ll options are simplified, and the macros brought into
line with other multi-platform implementations, and moved to the new
common location.

Two headers still need to be eliminated in order to include Tegra in a
multi-platform kernel/ <mach/{clk,powergate}.h>. A new common API needs
to be invented to replace parts of clk.h. powergate.h might be replaced
by regulators; this needs more investigation.

This pull request is based on tegra-for-3.8-dt, followed by a merge of
arm-soc's devel/debug_ll_init branch.

Olof Johansson bcc5155d05 ARM: tegra: cleanup for 3.8
Various trivial cleanup changes of the Tegra code for 3.8.
 
 Many of the changes simply remove useless #include statements, which
 enable those headers to be removed or moved later, as work towards
 multi-platform zImage support.
 
 <mach/{iram,io}map.h> are moved up to arch/arm/mach-tegra to prevent
 any new code outside mach-tegra from using them.
 
 Finally, the regulator definitions in all board device tree files are
 updated to use the new simpler syntax that was agreed upon.

Nathan Fontenot 1cf3d8b3d2 powerpc+of: Add of node/property notification chain for adds and removes
This patch moves the notification chain for updates to the device tree
from the powerpc/pseries code to the base OF code. This makes this
functionality available to all architectures.

Additionally the notification chain is updated to allow notifications
for property add/remove/update. To make this work a pointer to a new
struct (of_prop_reconfig) is passed to the routines in the notification chain.
The of_prop_reconfig property contains a pointer to the node containing the
property and a pointer to the property itself. In the case of property
updates, the property pointer refers to the new property.

Sachin Kamat a465348ff5 crypto: s5p-sss - Fix compilation error
struct s3c2410_dma_client gets defined multiple times as it is defined
in more than one header file. Changing it at the header file level causes
many more build breakages as they are interdependent in a complex way.
Hence fixing this problem by using the mach version of the header file.

Without this patch, following build error is observed:
arch/arm/plat-samsung/include/plat/dma-pl330.h:106:27: error:
