The new CPU clock type allows the use of generic CPUfreq driver.
Switch Exynos4x12 to using generic cpufreq driver.Previously (when exynos-cpufreq driver was used with boost
functionality) ARM_EXYNOS_CPU_FREQ_BOOST_SW config option
(which enabled boost functionality) selected EXYNOS_THERMAL
one. After switching Exynos4x12 platforms to use cpufreq-dt
driver boost support is enabled in the cpufreq-dt driver
itself (because there are turbo OPPs defined in the board's
DTS file). However we still would like to allow enabling
boost support only if thermal support is also enabled for
Exynos platforms. To achieve this make ARCH_EXYNOS config
option select THERMAL and EXYNOS_THERMAL ones.Please also note that the switch to use the generic cpufreq-dt
driver fixes the minor issue present with the old code (support
for 'boost' mode in the exynos-cpufreq driver was enabled for
all supported SoCs even though 'boost' frequency was provided
only for Exynos4x12 ones).Cc: Tomasz Figa

Pull more ACPI and power management updates from Rafael Wysocki:
"These are regression fixes (leds-gpio, ACPI backlight driver,
operating performance points library, ACPI device enumeration
messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device
PM), some cleanups in the operating performance points (OPP)
framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of
minor intel_pstate driver changes, a new MAINTAINERS entry for it and
an ACPI fan driver change needed for better support of thermal
management in user space.Specifics:
- Fix a regression in leds-gpio introduced by a recent commit that
inadvertently changed the name of one of the properties used by the
driver (Fabio Estevam).- Fix a regression in the ACPI backlight driver introduced by a
recent fix that missed one special case that had to be taken into
account (Aaron Lu).- Drop the level of some new kernel messages from the ACPI core
introduced by a recent commit to KERN_DEBUG which they should have
used from the start and drop some other unuseful KERN_ERR messages
printed by ACPI (Rafael J Wysocki).- Revert an incorrect commit modifying the cpupower tool (Prarit
Bhargava).- Fix two regressions introduced by recent commits in the OPP library
and clean up some existing minor issues in that code (Viresh
Kumar).- Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
tree (or drop it where that can be done) in order to make it
possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
Hansson, Ludovic Desroches).There will be one more "CONFIG_PM_RUNTIME removal" batch after this
one, because some new uses of it have been introduced during the
current merge window, but that should be sufficient to finally get
rid of it.- Make the ACPI EC driver more robust against race conditions related
to GPE handler installation failures (Lv Zheng).- Prevent the ACPI device PM core code from attempting to disable
GPEs that it has not enabled which confuses ACPICA and makes it
report errors unnecessarily (Rafael J Wysocki).- Add a "force" command line switch to the intel_pstate driver to
make it possible to override the blacklisting of some systems in
that driver if needed (Ethan Zhao).- Improve intel_pstate code documentation and add a MAINTAINERS entry
for it (Kristen Carlson Accardi).- Make the ACPI fan driver create cooling device interfaces witn
names that reflect the IDs of the ACPI device objects they are
associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").That's necessary for user space thermal management tools to be able
to connect the fans with the parts of the system they are supposed

This patch modifies Exynos Power Management Unit (PMU) initialization
implementation in following way:- Added platform driver support for Exynos PMU IP.
- Added platform struct exynos_pmu_data to hold platform specific data.
- For each SoC's PMU support now we can add platform data and statically
bind PMU configuration and SoC specific initialization function.
- Separate each SoC's PMU initialization function and make it as part of
platform data.
- It also removes uses of soc_is_exynosXYZ().Signed-off-by: Pankaj Dubey

Pull ACPI and power management updates from Rafael Wysocki:
"Again, ACPICA leads the pack (47 commits), followed by cpufreq (18
commits) and system suspend/hibernation (9 commits).From the new code perspective, the ACPICA update brings ACPI 5.1 to
the table, including a new device configuration object called _DSD
(Device Specific Data) that will hopefully help us to operate device
properties like Device Trees do (at least to some extent) and changes
related to supporting ACPI on ARM.Apart from that we have hibernation changes making it use radix trees
to store memory bitmaps which should speed up some operations carried
out by it quite significantly. We also have some power management
changes related to suspend-to-idle (the "freeze" sleep state) support
and more preliminary changes needed to support ACPI on ARM (outside of
ACPICA).The rest is fixes and cleanups pretty much everywhere.
Specifics:
- ACPICA update to upstream version 20140724. That includes ACPI 5.1
material (support for the _CCA and _DSD predefined names, changes
related to the DMAR and PCCT tables and ARM support among other
things) and cleanups related to using ACPICA's header files. A
major part of it is related to acpidump and the core code used by
that utility. Changes from Bob Moore, David E Box, Lv Zheng,
Sascha Wildner, Tomasz Nowicki, Hanjun Guo.- Radix trees for memory bitmaps used by the hibernation core from

as the "freeze" sleep state) using ACPI-based PCI wakeup signaling

Pull ARM updates from Russell King:
"This contains the usual updates from other people (listed below) and
the usual random muddle of miscellaneous ARM updates which cover some
low priority bug fixes and performance improvements.I've started to put the pull request wording into the merge commits,
which are:- NoMMU stuff:
This includes the following series sent earlier to the list:
- nommu-fixes
- R7 Support
- MPU supportI've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
were discussing today until we've reached a conclusion/that's had
some more review.This is rebased (and re-tested) on your devel-stable branch because
otherwise there were going to be conflicts with Uwe's V7M work now
that you've merged that. I've included the fix for limiting MPU to
CPU_V7.- Huge page support
These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM. Only long descriptors (LPAE) are supported
in this series.The code has been tested on an Arndale board (Exynos 5250).
- LPAE updates
Please pull these miscellaneous LPAE fixes I've been collecting for
a while now for 3.11. They've been tested and reviewed by quite a
few people, and most of the patches are pretty trivial. -- Will Deacon.- arch_timer cleanups
Please pull these arch_timer cleanups I've been holding onto for a
while. They're the same as my last posting, but have been rebased
to v3.10-rc3.- mpidr linearisation (multiprocessor id register - identifies which
CPU number we are in the system)This patch series that implements MPIDR linearization through a
simple hashing algorithm and updates current cpu_{suspend}/{resume}
code to use the newly created hash structures to retrieve context
pointers. It represents a stepping stone for the implementation of
power management code on forthcoming multi-cluster ARM systems.It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
OMAP4 and Tegra, with processors hitting low-power states requiring
warm-boot resume through the cpu_resume code path"* 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (77 commits)
ARM: 7775/1: mm: Remove do_sect_fault from LPAE code
ARM: 7777/1: Avoid extra calls to the C compiler
ARM: 7774/1: Fix dtb dependency to use order-only prerequisites
ARM: 7770/1: remove residual ARMv2 support from decompressor
ARM: 7769/1: Cortex-A15: fix erratum 798181 implementation
ARM: 7768/1: prevent risks of out-of-bound access in ASID allocator
ARM: 7767/1: let the ASID allocator handle suspended animation
ARM: 7766/1: versatile: don't mark pen as __INIT
ARM: 7765/1: perf: Record the user-mode PC in the call chain.
ARM: 7735/2: Preserve the user r/w register TPIDRURW on context switch and fork
ARM: kernel: implement stack pointer save array through MPIDR hashing
ARM: kernel: build MPIDR hash function data structure
ARM: mpu: Ensure that MPU depends on CPU_V7
ARM: mpu: protect the vectors page with an MPU region
ARM: mpu: Allow enabling of the MPU via kconfig
ARM: 7758/1: introduce config HAS_BANDGAP
ARM: 7757/1: mm: don't flush icache in switch_mm with hardware broadcasting
ARM: 7751/1: zImage: don't overwrite ourself with a page table
ARM: 7749/1: spinlock: retry trylock operation if strex fails on free lock
ARM: 7748/1: oabi: handle faults when loading swi instruction from userspace

Pull ARM SoC late changes from Arnd Bergmann:
"These are changes that arrived a little late before the merge window
or that have multiple dependencies on previous branches so they did
not fit into one of the earlier ones. There are 10 branches merged
here, a total of 39 non-merge commits. Contents are a mixed bag for
the above reasons:* Two new SoC platforms: ST microelectronics stixxxx and the TI
'Nspire' graphing calculator. These should have been in the 'soc'
branch but were a little late
* Support for the Exynos 5420 variant in mach-exynos, which is based
on the other exynos branches to avoid conflicts.
* Various small changes for sh-mobile, ux500 and davinci
* Common clk support for MSM"* tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits)
