Pull ARM SoC cleanups from Arnd Bergmann:
"These cleanup patches are mainly move stuff around and should all be
harmless. They are mainly split out so that other branches can be
based on top to avoid conflicts.
Notable changes are:
- We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used (Uwe Kleine-König)
- The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions (Kumar Gala)
- A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
- Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
- mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
- at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people)"

The msm_sdcc MMC driver and the msm_serial_hs uart driver both
use the pre-dmaengine interfaces provided by the MSM platform.
Since these drivers can be loadable modules, we should export
the functions used in the drivers.

MSM7X00A has an open-coded version of debug_ll_io_init so it
can use MT_DEVICE_NONSHARED as required by the platform.
However, this fails to build on no-MMU kernels because the
debug_ll_addr function is not available. Since the iotable_init
function doesn't actually do anyting in this configuration,
we can simply get away by enclosing the broken function call
in an #ifdef, which seems to be the least ugly workaround.

next/cleanup
This cleanup series gets rid of <mach/timex.h> for platforms not using
ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
387798b (ARM: initial multiplatform support).)
To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc
(with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
Compared to the previous pull request there was another patch added that
fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
squash this fix into the original commit to save him from the need to
reverify the series.

This makes it easy to add SMP support for new devices by keying
on a device node for the release sequence. We add the
enable-method property for the cpus property to specify that we
want to use the gcc-msm8660 release sequence (which is going to
look for the global clock controller device node to map some
Scorpion specific power and control registers). We also remove
the nr_cpus detection code as that is done generically in the DT
CPU detection code.

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"

"This branch contains code cleanups, moves and removals for 3.12.
There's a large number of various cleanups, and a nice net removal of
13500 lines of code.
Highlights worth mentioning are:
- A series of patches from Stephen Boyd removing the ARM local timer
API.
- Move of Qualcomm MSM IOMMU code to drivers/iommu.
- Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM
driver and switching over to the drivers/pwm one.
- Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
There's also a move of a header file out of include/linux/i2c/ to
platform_data, where it really belongs. It touches mostly ARM
platform code for include changes so we took it through our tree"

Pull tty/serial driver patches from Greg KH:
"Here's the big tty/serial driver pull request for 3.12-rc1.
Lots of n_tty reworks to resolve some very long-standing issues,
removing the 3-4 different locks that were taken for every character.
This code has been beaten on for a long time in linux-next with no
reported regressions.
Other than that, a range of serial and tty driver updates and
revisions. Full details in the shortlog"

In downstream kernel we've standardized the clock consumer names
that MSM device drivers use. Replace the uart specific clock
names in this driver with the more standard 'core' and 'iface'
names. Also simplify the code by assuming that clk_prepare_enable
and clk_disable_unprepare() will properly check for NULL pointers
(it will because MSM uses the common clock framework).

Only the non-dt based MSM platforms need to map memory from their
machine descriptor. Unfortunately it is always compiled if
ARCH_MSM=y and the file also has mach/ includes in it. Since
dt-based MSM platforms aren't actually using anything in this
file just compile io.c on the non-dt based MSM platforms. This
allows the dt-based platforms to participate in the
multi-platform kernel.

Two header files exist in mach-msm's include/mach directory that
are only used by the MSM iommu driver. Move these files to the
iommu driver directory and prefix them with "msm_". This allows
us to compile the MSM iommu driver on multi-platform kernels.

The iommu devices are registered in software, when they should
really be part of the DT. Since we don't currently have DT
bindings in place for the MSM iommu driver just remove this file
for the time being. This is not removing any functionality anyway
because these devices aren't probing today due to missing clocks.

The contents of mach/board.h are only used by files within
mach-msm so there is no need to export this file outside of the

Nobody is using these mappings so just drop them. of_iomap() in

git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into fixes
From David Brown, fixes for MSM for 3.11:
Two small fixes for MSM.
The first fixes the a gpio controller register address. I didn't see
any acks from the devicetree maintainers, so I've copied them on this
pull request. The change itself is minor, and just to the register
address.
The second change removes the gpiomux V1 code from MSM. This was
breaking compilation for some of the targets.

git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/cleanup
From Stephen Boyd:
Now that we have a generic arch hook for broadcast we can remove the
local timer API entirely. Doing so will reduce code in ARM core, reduce
the architecture dependencies of our timer drivers, and simplify the code
because we no longer go through an architecture layer that is essentially
a hotplug notifier.

ARM: smp: Remove local timer API
clocksource: time-armada-370-xp: Divorce from local timer API

Resolved a large number of conflicts due to __cpuinit cleanups, etc.

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings. In any case, they are temporary and harmless.
This removes all the ARM uses of the __cpuinit macros from C code,
and all __CPUINIT from assembly code. It also had two ".previous"
section statements that were paired off against __CPUINIT
(aka .section ".cpuinit.text") that also get removed here.
