This is the bulk of new SoC enablement and other platform changes for 3.17:
* Samsung S5PV210 has been converted to DT and multiplatform
* Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
* Kirkwood, one of the popular Marvell platforms, is folded into the
mvebu platform code, removing mach-kirkwood.
* Hwmod data for TI AM43xx and DRA7 platforms.
* More additions of Renesas shmobile platform support
* Removal of plat-samsung contents that can be removed with S5PV210 being
multiplatform/DT-enabled and the other two old platforms being removed.
New platforms (most with only basic support right now):
* Hisilicon X5HD2 settop box chipset is introduced
* Mediatek MT6589 (mobile chipset) is introduced
* Broadcom BCM7xxx settop box chipset is introduced
+ as usual a lot other pieces all over the platform code.

This driver will be able to manage the cpuidle for more SoCs than just
Armada 370 and XP. It will also support Armada 38x and potentially
other SoC of the Marvell Armada EBU family. To take this into account,
this patch renames the driver and its symbols.
It also changes the driver name from cpuidle-armada-370-xp to
cpuidle-armada-xp, because separate platform drivers will be
registered for the other SoC types. This change must be done
simultaneously in the cpuidle driver and in the PMSU code in order to
remain bisectable.

Pull ACPI and power management updates from Rafael Wysocki:
"ACPICA is the leader this time (63 commits), followed by cpufreq (28
commits), devfreq (15 commits), system suspend/hibernation (12
commits), ACPI video and ACPI device enumeration (10 commits each).
We have no major new features this time, but there are a few
significant changes of how things work. The most visible one will
probably be that we are now going to create platform devices rather
than PNP devices by default for ACPI device objects with _HID. That
was long overdue and will be really necessary to be able to use the
same drivers for the same hardware blocks on ACPI and DT-based systems
going forward. We're not expecting fallout from this one (as usual),
but it's something to watch nevertheless.
The second change having a chance to be visible is that ACPI video
will now default to using native backlight rather than the ACPI
backlight interface which should generally help systems with broken
Win8 BIOSes. We're hoping that all problems with the native backlight
handling that we had previously have been addressed and we are in a
good enough shape to flip the default, but this change should be easy
enough to revert if need be.
In addition to that, the system suspend core has a new mechanism to
allow runtime-suspended devices to stay suspended throughout system
suspend/resume transitions if some extra conditions are met
(generally, they are related to coordination within device hierarchy).
However, enabling this feature requires cooperation from the bus type
layer and for now it has only been implemented for the ACPI PM domain
(used by ACPI-enumerated platform devices mostly today).
Also, the acpidump utility that was previously shipped as a separate
tool will now be provided by the upstream ACPICA along with the rest
of ACPICA code, which will allow it to be more up to date and better
supported, and we have one new cpuidle driver (ARM clps711x).
The rest is improvements related to certain specific use cases,
cleanups and fixes all over the place.
Specifics:
- ACPICA update to upstream version 20140424. That includes a number
of fixes and improvements related to things like GPE handling,
table loading, headers, memory mapping and unmapping, DSDT/SSDT
overriding, and the Unload() operator. The acpidump utility from

- ACPI device enumeration changes to create platform devices rather

devices will still be created for the ACPI device object with
device IDs corresponding to real PNP devices, so that change should
not break things left and right, and we're expecting to see more
and more ACPI-enumerated platform devices in the future. From

SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.
This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.
The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.
After discussion at last year's KS (and some more on the mailing lists),
we are here adding a drivers/soc directory. The purpose of this is
to keep per-vendor shared code that's needed by different drivers but
that doesn't fit into the MFD (nor drivers/platform) model. We expect
to keep merging contents for this hierarchy through arm-soc so we can
keep an eye on what the vendors keep adding here and not making it a
free-for-all to shove in crazy stuff.

Add cpuidle support for ARM Cirrus Logic CLPS711X CPUs.
This CPU has an unique internal register and write to this location
will put the system into the Idle State by halting the clock to the
processor until an interrupt is generated.

As the cpuidle driver code has no more the dependency with the pm code, the
'standby' callback being passed as a parameter to the device's platform data,
we can move the cpuidle driver in the drivers/cpuidle directory.

Following the reorganization of CPU idle drivers configurations into an ARM
specific Kconfig, the existing idle drivers Kconfig entries were renamed and
moved to the Kconfig.arm file. Makefile entries were updated accordingly.
This patch renames the entries in Kconfig.arm and makefile to make the newly
added big.LITTLE CPUidle driver compliant with the new naming convention.

This updates the Calxeda cpuidle driver to use PSCI calls to powergate
cores. This also enables cpuidle for the ECX-2000.
This could possibly become a generic PSCI driver, but there are no other
PSCI users in the kernel other than mach-virt.

This branch contains ARM SoC related driver updates for v3.12. The
only thing this cycle are core PM updates and CPUidle support for
ARM's TC2 big.LITTLE development platform.
Conflicts:
One cleanup/reorg conflict with a new entry in
drivers/cpuidle/Makefile. Append the new entry after the existing
ones. A follow up patch for v3.12-rc will make the new entry conform
to the cleanup/reorg.
