Pull late ARM Exynos multiplatform changes from Arnd Bergmann:
"These continue the multiplatform support for exynos, adding support
for building most of the essential drivers (clocksource, clk, irqchip)
when combined with other platforms. As a result, it should become
really easy to add full multiplatform exynos support in 3.11, although
we don't yet enable it for 3.10.
The changes were not included in the earlier multiplatform series in
order to avoid clashes with the other Exynos updates.
This also includes work from Tomasz Figa to fix the pwm clocksource
code on Exynos, which is not strictly required for multiplatform, but
related to the other patches in this set and needed as a bug fix for
at least one board."

Pull ARM SoC device tree updates (part 2) from Arnd Bergmann:
"These are mostly new device tree bindings for existing drivers, as
well as changes to the device tree source files to add support for
those devices, and a couple of new boards, most notably Samsung's
Exynos5 based Chromebook.
The changes depend on earlier platform specific updates and touch the
usual platforms: omap, exynos, tegra, mxs, mvebu and davinci."

This series from Tomasz Figa restores support for the pwm clocksource
in Exynos, which was broken during the conversion of the platform
to the common clk framework. The clocksource is only used in one
board in the mainline kernel (universal_c210), and this makes it
work for DT based probing as well as restoring the non-DT based
case.

"Two platforms, bcm and exynos have their own firmware interfaces using
the "secure monitor call", this adds support for those.
We had originally planned to have a third set of patches in here,
which would extend support for the existing generic "psci" call that
is used on multiple platforms as well as Xen and KVM guests, but that
ended up getting dropped because the patches were not ready in time."

Pull ARM SoC driver changes from Olof Johansson:
"This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem specific
interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into platform
specific interface, or to get called from platform specific code, as
long as all information about the hardware is provided through a
device tree.
Most of the drivers we touch this time are for clocksource. Since now
most of them are part of drivers/clocksource, I expect that we won't
have to touch these again from arm-soc and can let the clocksource
maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the merge
conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface for
taking devices on the SoC out of reset or back into reset. Patches to
use this interface on i.MX follow later in this merge window, and we
are going to have other platforms (at least tegra and sirf) get
converted in 3.11. This will let us get rid of platform specific
callbacks in a number of platform independent device drivers."

This reverts commit bd51de53e1be9896d815bbea30560262216d4616.
Turns out that multiplatform breaks some uses cases, such as when you
have an existing defconfig, since it adds the new EXYNOS_SINGLE config
option as a dependecy. As a result, nearly all exynos config options
will be disabled by default.
Reverting instead of rebasing since this branch is pulled in as a
dependency elsewhere.

The platform code knows the IRQ base, while the irqchip driver
should really not. This is a littly hacky because we still
hardwire the IRQ base to 160 for the combiner in the DT case,
when we should really use -1. Removing that line will cause
a linear IRQ domain to be use, as we should.

We can find out the number of combined IRQs from the device
tree, but in case of ATAGS boot, the driver currently uses
hardcoded values based on the SoC type. We can't do that
in general for a multiplatform kernel, so let's instead pass
this information from platform code directly in case of
ATAGS boot.

For the non-DT case, the mct_init() function requires access

The new common clock drivers for exynos are using compile

This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.
The multiplatform variant has a number of limitations at the moment:
* It only supports DT-enabled machines. This is not a problem in
the long run, as non-DT machines for exynos are going away.
The main problem here is that the gpio code and the exynos_eint
irqchip are not multiplatform capable but still required for
ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
multiplatform.
The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.

This patch defines irq numbers of ARM performance monitoring unit for exynos4.
Firs of all, we need to fix IRQ_PMU correctly and to split pmu initialization
of exynos from plat-samsung for easily defining it.
The number of CPU cores and PMU irq numbers are vary according to soc types.
So, we need to identify each soc type using soc_is_xxx function and to define
the pmu irqs dynamically. For example, the exynos4412 has 4 cpu cores and pmus.

Pull ARM SoC cleanups from Arnd Bergmann:
"A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even
specify the driver they use, it can all get configured from the device
tree as we do for normal device drivers. The clocksource changes
basically touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose their
headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code."

Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init
for GIC init). This commit split the irqchip initialization into 2 calls
to of_irq_init. This does not work because of_irq_init requires interrupt
parents to be in the match list.
Rather than reverting exynos changes, make it do the proper thing by using
IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.

"Continued device tree conversion and enablement across a number of

ux500 has seen continued conversion for platforms. Several platforms
have seen pinctrl-via-devicetree conversions for simpler
multiplatform. Tegra is adding data for new devices/drivers, and
Exynos has a bunch of new bindings and devices added as well.
So, pretty much the same progression in the right direction as the
last few releases."

Two new platforms have been added, the sunxi platforms (Allwinner A1x
SoCs) by Maxime Ripard, and a generic Broadcom platform for a new

keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian
Daudt.

ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's
also taken on maintainership of the platform.

converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms."

The recent commit "ARM: EXYNOS: add support for EXYNOS5440 SoC" broke
support for exynos5250 because of_machine_is_compatible() was used too
early in the boot process. It also probably meant that the exynos5440
failed to use the proper iotable. Switch to use
of_flat_dt_is_compatible() in both of these cases.
The failure I was seeing in exynos5250 because of this was:
Division by zero in kernel.
