8264fce6de Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux 
Pull thermal management updates from Zhang Rui:
 "Sorry that I missed the merge window as there is a bug found in the
  last minute, and I have to fix it and wait for the code to be tested
  in linux-next tree for a few days.  Now the buggy patch has been
  dropped entirely from my next branch.  Thus I hope those changes can
  still be merged in 3.18-rc2 as most of them are platform thermal
  driver changes.

  Specifics:

   - introduce ACPI INT340X thermal drivers.

     Newer laptops and tablets may have thermal sensors and other
     devices with thermal control capabilities that are exposed for the
     OS to use via the ACPI INT340x device objects.  Several drivers are
     introduced to expose the temperature information and cooling
     ability from these objects to user-space via the normal thermal
     framework.

     From: Lu Aaron, Lan Tianyu, Jacob Pan and Zhang Rui.

   - introduce a new thermal governor, which just uses a hysteresis to
     switch abruptly on/off a cooling device.  This governor can be used
     to control certain fan devices that can not be throttled but just
     switched on or off.  From: Peter Feuerer.

   - introduce support for some new thermal interrupt functions on
     i.MX6SX, in IMX thermal driver.  From: Anson, Huang.

   - introduce tracing support on thermal framework.  From: Punit
     Agrawal.

   - small fixes in OF thermal and thermal step_wise governor"

Pull mailbox framework from Jassi Brar:
 "A framework for Mailbox controllers and clients have been cooking for
  more than a year now.

  Everybody in the CC list had been copied on patchset revisions and
  most of them have made sounds of approval, though just one concrete
  Reviewed-by.  The patchset has also been in linux-next for a couple of
  weeks now and no conflict has been reported.  The framework has the
  backing of at least 5 platforms, though I can't say if/when they
  upstream their drivers (some businesses have 'changed')"

4d3639ac3c ARM: SoC fixes for -rc1 
A batch of fixes that have come in during the merge window.
 
 Some of them are defconfig updates for things that have now landed,
 some errata additions and a few general scattered fixes.
 
 There's also a qcom DT update that adds support for SATA on AP148,
 and basic support for Sony Xperia Z1 and CM-QS600 platforms that seemed
 isolated enough that we could merge it even if it's late.

Pull MTD update from Brian Norris:
 "Sorry for delaying this a bit later than usual.  There's one mild
  regression from 3.16 that was noticed during the 3.17 cycle, and I
  meant to send a fix for it along with this pull request.  I'll
  probably try to queue it up for a later pull request once I've had a
  better look at it, hopefully by -rc2 at the latest.

  Summary for this pull:

  NAND
   - Cleanup for Denali driver
   - Atmel: add support for new page sizes
   - Atmel: fix up 'raw' mode support
   - Atmel: miscellaneous cleanups
   - New timing mode helpers for non-ONFI NAND
   - OMAP: allow driver to be (properly) built as a module
   - bcm47xx: RESET support and other cleanups

  SPI NOR
   - Miscellaneous cleanups, to prepare framework for wider use (some
     further work still pending)
   - Compile-time configuration to select 4K vs.  64K support for flash
     that support both (necessary for using UBIFS on some SPI NOR)

  A few scattered code quality fixes, detected by Coverity

  See the changesets for more"

c0fa2373f8 The clk tree changes for 3.18 are dominated by clock drivers. Mostly 
fixes and enhancements to existing drivers as well as new drivers. This
 tag contains a bit more arch code than I usually take due to some OMAP2+
 changes. Additionally it contains the restart notifier handlers which
 are merged as a dependency into several trees.
 
 The PXA changes are the only messy part. Due to having a stable tree I
 had to revert one patch and follow up with one more fix near the tip of
 this tag. Some dead code is introduced but it will soon become live code
 after 3.18-rc1 is released as the rest of the PXA family is converted
 over to the common clock framework.
 
 Another trend in this tag is that multiple vendors have started to push
 the complexity of changing their CPU frequency into the clock driver,
 whereas this used to be done in CPUfreq drivers.
 
 Changes to the clk core include a generic gpio-clock type and a
 clk_set_phase() function added to the top-level clk.h api. Due to some
 confusion on the fbdev mailing list the kernel boot parameters
 documentation was updated to further explain the clk_ignore_unused
 parameter, which is often required by users of the simplefb driver.
 Finally some fixes to the locking around the clock debugfs stuff was
 done to prevent deadlocks when interacting with other subsystems.

53b26b9bc9 stmmac: dwmac-sti: review the glue-logic for STi4xx and STiD127 SoCs 
This patch is to review the whole glue logic adopted on STi SoCs that
was bugged.

In the old glue-logic there was a lot of confusion when setup the
retiming especially for STiD127 where, for example, the bits 6 and 7
(in the GMAC  control register) have a different meaning of what is
used for STiH4xx SoCs. So we cannot adopt the same glue for all these
SoCs.
Moreover, GiGa on STiD127 didn't work and, for all the SoCs, the RGMII
couldn't run when the speed was 10Mbps (because the clock was not properly
managed).
Note that the phy clock needs to be provided by the platform as well as
documented in the related binding file (updated as consequence).

The old code supported too many configurations never adopted and validated.
This made the code very complex to maintain and debug in case of issues.

The patch simplifies all the configurations as commented in the tables
inside the file and obviously it has been tested on all the boards
based on the SoCs mentioned.

With this patch, the dwmac-sti is also ready to support new configurations that
will be available on next SoC generations.

df9e26d093 rtc: s3c: add support for RTC of Exynos3250 SoC 
Add support for RTC of Exynos3250 SoC.  The Exynos3250 needs source
clock(32.768KHz) for RTC block.  If source clock of RTC is registerd on
clock list of common clk framework, Exynos RTC drvier have to control
this clock.

Clock list for s3c-rtc device:
- rtc : CLK_RTC of CLK_GATE_IP_PERIR is gate clock for RTC.
- rtc_src : XrtcXTI is 32.768.kHz source clock for RTC.
 (XRTCXTI: Specifies a clock from 32.768 kHz crystal pad with XRTCXTI and
 XRTCXTO pins. RTC uses this clock as the source of a real-time clock.)

e98d6e7f76 Devicetree changes for v3.18 
This branch contains bug fixes and new features for the devicetree code.
 Most of the changes are either new testcases for the selftest code or
 documentation changes. The most notable change is the addition of a
 phandle resolver for use when grafting in a second device tree blob into
 the core tree. The resolver isn't currently used by anything other than
 the selftest module, but it will be used to support device tree
 overlays; probably in the v3.19 timeframe.
 
 Also note that I've moved my normal tree from git.secretlab.ca to
 git.kernel.org.

a2ce35273c sound updates for 3.18-rc1 
This time it's a relatively calm update batch, but the amount isn't
 too small in the end.  Here we go over some highlights:
 
 - ALSA core
   - One major change is the support of nonatomic PCM operations.
     This allows the trigger and other callbacks to call schedule(),
     which would be useful for mailbox type communications.  Already
     some drivers (Digigram ones) have been converted to use together
     with threaded irqs as an example.
   - Improvement / fixes of DSD PCM format support
 
 - HD-audio
   - Large volume of rewrites are found in Realtek codec driver for
     converting Dell and HP quirks to generic forms.
   - Inverted dmic code cleanup from David.
   - Realtek COEF access has been optimized.
   - Now HD-audio jack infrastructure allows multiple callbacks, which
     fixes / simplifies the jack-dependent power controls on STAC/IDT
     and VIA codecs.
   - Many additional device-specific fixups as usual
   - A few deadcode cleanups, CA0132 code cleanup, etc.
 
 - ASoC
   - More componentization work from Lars-Peter, this time mainly
     cleaning up the suspend and bias level transition callbacks.
   - Real system support for the Intel drivers and a bunch of fixes
     and enhancements for the associated CODEC drivers, this is going
     to need a lot quirks over time due to the lack of any firmware
     description of the boards.
   - Jack detect support for simple card from Dylan Reid.
   - A bunch of small fixes and enhancements for the Freescale
     drivers.
   - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32,
     Everest Semiconductor ES8328 and Freescale cards using the ASRC
     in newer i.MX processors.
   - A few simple-card fixes, mostly cleanups but also a fix for
   - interaction between GPIO 0 and simple-card.
 
 - Misc
   - Virtuoso / Oxygen updates by Clemens
   - USB-audio: Yamaha MOTIF XF MIDI port name fixes
   - Conversion of kernel messages to standard dev_*() in ctxfi
     driver.

after reset. If this differs from the actual input clock, then
register 0x1f bit 7 must be changed.

Pull libata update from Tejun Heo:
 "AHCI is getting per-port irq handling and locks for better
  scalability.  The gain is not huge but measureable with multiple high
  iops devices connected to the same host; however, the value of
  threaded IRQ handling seems negligible for AHCI and it likely will
  revert to non-threaded handling soon.

  Another noteworthy change is George Spelvin's "libata: Un-break ATA
  blacklist".  During 3.17 devel cycle, the libata blacklist glob
  matching got generalized and rewritten; unfortunately, the patch
  forgot to swap arguments to match the new match function and ended up
  breaking blacklist matching completely.  It got noticed only a couple
  days ago so it couldn't make for-3.17-fixes either.  :(

  Other than the above two, nothing too interesting - the usual cleanup
  churns and device-specific changes"

b528392669 ACPI and power management updates for 3.18-rc1 
- Rework the handling of wakeup IRQs by the IRQ core such that
    all of them will be switched over to "wakeup" mode in
    suspend_device_irqs() and in that mode the first interrupt
    will abort system suspend in progress or wake up the system
    if already in suspend-to-idle (or equivalent) without executing
    any interrupt handlers.  Among other things that eliminates the
    wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
    flag with interrupts which don't really need it and should not
    use it (Thomas Gleixner and Rafael J Wysocki).
 
  - Switch over ACPI to handling wakeup interrupts with the help
    of the new mechanism introduced by the above IRQ core rework
    (Rafael J Wysocki).
 
  - Rework the core generic PM domains code to eliminate code that's
    not used, add DT support and add a generic mechanism by which
    devices can be added to PM domains automatically during
    enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
 
  - Add debugfs-based mechanics for debugging generic PM domains
    (Maciej Matraszek).
 
  - ACPICA update to upstream version 20140828.  Included are updates
    related to the SRAT and GTDT tables and the _PSx methods are in
    the METHOD_NAME list now (Bob Moore and Hanjun Guo).
 
  - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
    can't really be done in a straightforward way) to prevent
    Thunderbolt from being turned off on Apple systems after boot
    (or after resume from system suspend) and rework the ACPI Smart
    Battery Subsystem (SBS) driver to work correctly with Apple
    platforms (Matthew Garrett and Andreas Noever).
 
  - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
    code, adding support for 133MHz I2C source clock on Intel Baytrail
    to it and making it avoid using UART RTS override with Auto Flow
    Control (Heikki Krogerus).
 
  - ACPI backlight updates removing the video_set_use_native_backlight
    quirk which is not necessary any more, making the code check the
    list of output devices returned by the _DOD method to avoid
    creating acpi_video interfaces that won't work and adding a quirk
    for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
 
  - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
 
  - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
    Sudip Mukherjee, Yijing Wang, and Zhang Rui).
 
  - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
    Rasmus Villemoes).
 
  - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
    change among other things), ppc-corenet, powernv (Viresh Kumar,
    Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
 
  - cpuidle support for DT-based idle states infrastructure, new
    ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
    Rasmus Villemoes).
 
  - ARM big.LITTLE cpuidle driver updates: support for DT-based
    initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
    Kevin Hilman).
 
  - Rework of the test_suspend kernel command line argument and
    a new trace event for console resume (Srinivas Pandruvada,
    Todd E Brandt).
 
  - Second attempt to optimize swsusp_free() (hibernation core) to
    make it avoid going through all PFNs which may be way too slow on
    some systems (Joerg Roedel).
 
  - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
 
  - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
    entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).
 
  - PM core fix related to clock management (Geert Uytterhoeven).
 
  - PM core's sysfs code cleanup (Johannes Berg).

Merge tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "Features-wise, to me the most important this time is a rework of
  wakeup interrupts handling in the core that makes them work
  consistently across all of the available sleep states, including
  suspend-to-idle.  Many thanks to Thomas Gleixner for his help with
  this work.

  Second is an update of the generic PM domains code that has been in
  need of some care for quite a while.  Unused code is being removed, DT
  support is being added and domains are now going to be attached to
  devices in bus type code in analogy with the ACPI PM domain.  The
  majority of work here was done by Ulf Hansson who also has been the
  most active developer this time.

  Apart from this we have a traditional ACPICA update, this time to
  upstream version 20140828 and a few ACPI wakeup interrupts handling
  patches on top of the general rework mentioned above.  There also are
  several cpufreq commits including renaming the cpufreq-cpu0 driver to
  cpufreq-dt, as this is what implements generic DT-based cpufreq
  support, and a new DT-based idle states infrastructure for cpuidle.

  In addition to that, the ACPI LPSS driver is updated, ACPI support for
  Apple machines is improved, a few bugs are fixed and a few cleanups
  are made all over.

  Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
  maintained by Kevin Hilman that will be merged through the PM tree.

  Numbers-wise, the generic PM domains update takes the lead this time
  with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
  place goes to the wakeup interrupts handling rework (13 commits).

  Specifics:

   - Rework the handling of wakeup IRQs by the IRQ core such that all of
     them will be switched over to "wakeup" mode in suspend_device_irqs()
     and in that mode the first interrupt will abort system suspend in
     progress or wake up the system if already in suspend-to-idle (or
     equivalent) without executing any interrupt handlers.  Among other
     things that eliminates the wakeup-related motivation to use the
     IRQF_NO_SUSPEND interrupt flag with interrupts which don't really
     need it and should not use it (Thomas Gleixner and Rafael Wysocki)

   - Switch over ACPI to handling wakeup interrupts with the help of the
     new mechanism introduced by the above IRQ core rework (Rafael Wysocki)

   - Rework the core generic PM domains code to eliminate code that's
     not used, add DT support and add a generic mechanism by which
     devices can be added to PM domains automatically during enumeration
     (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).

   - Add debugfs-based mechanics for debugging generic PM domains
     (Maciej Matraszek).

   - ACPICA update to upstream version 20140828.  Included are updates
     related to the SRAT and GTDT tables and the _PSx methods are in the
     METHOD_NAME list now (Bob Moore and Hanjun Guo).

   - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
     can't really be done in a straightforward way) to prevent
     Thunderbolt from being turned off on Apple systems after boot (or
     after resume from system suspend) and rework the ACPI Smart Battery
     Subsystem (SBS) driver to work correctly with Apple platforms
     (Matthew Garrett and Andreas Noever).

   - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the code,
     adding support for 133MHz I2C source clock on Intel Baytrail to it
     and making it avoid using UART RTS override with Auto Flow Control
     (Heikki Krogerus).

   - ACPI backlight updates removing the video_set_use_native_backlight
     quirk which is not necessary any more, making the code check the
     list of output devices returned by the _DOD method to avoid
     creating acpi_video interfaces that won't work and adding a quirk
     for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak)

   - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin)

   - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
     Sudip Mukherjee, Yijing Wang, and Zhang Rui)

   - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
     Rasmus Villemoes)

   - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name change
     among other things), ppc-corenet, powernv (Viresh Kumar, Preeti U
     Murthy, Shilpasri G Bhat, Lucas Stach)

   - cpuidle support for DT-based idle states infrastructure, new ARM64
     cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi, Rasmus
     Villemoes)

   - ARM big.LITTLE cpuidle driver updates: support for DT-based
     initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
     Kevin Hilman)

   - Rework of the test_suspend kernel command line argument and a new
     trace event for console resume (Srinivas Pandruvada, Todd E Brandt)

   - Second attempt to optimize swsusp_free() (hibernation core) to make
     it avoid going through all PFNs which may be way too slow on some
     systems (Joerg Roedel)

   - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).

   - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS entry
     update in MAINTAINERS (Heiko Stübner, Kevin Hilman)

   - PM core fix related to clock management (Geert Uytterhoeven)

   - PM core's sysfs code cleanup (Johannes Berg)"

ea584595fc This is the bulk of GPIO changes for the v3.18 development 
cycle:
 
 - Increase the default ARCH_NR_GPIO from 256 to 512. This
   was done to avoid having a custom <asm/gpio.h> header for
   the x86 architecture - GPIO is custom and complicated
   enough as it is already! We want to move to a radix to
   store the descriptors going forward, and finally get rid
   of this fixed array size altogether.
 
 - Endgame patching of the gpio_remove() semantics initiated
   by Abdoulaye Berthe. It is not accepted by the system that
   the removal of a GPIO chip fails during e.g. reboot or
   shutdown, and therefore the return value has now painfully
   been refactored away. For special cases like GPIO expanders
   on a hot-pluggable bus like USB, we may later add some
   gpiochip_try_remove() call, but for the cases we have now,
   return values are moot.
 
 - Some incremental refactoring of the gpiolib core and ACPI
   GPIO library for more descriptor usage.

Merge tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO changes from Linus Walleij:
 "This is the bulk of GPIO changes for the v3.18 development cycle:

   - Increase the default ARCH_NR_GPIO from 256 to 512.  This was done
     to avoid having a custom <asm/gpio.h> header for the x86
     architecture - GPIO is custom and complicated enough as it is
     already! We want to move to a radix to store the descriptors going
     forward, and finally get rid of this fixed array size altogether.

   - Endgame patching of the gpio_remove() semantics initiated by
     Abdoulaye Berthe.  It is not accepted by the system that the
     removal of a GPIO chip fails during eg reboot or shutdown, and
     therefore the return value has now painfully been refactored away.
     For special cases like GPIO expanders on a hot-pluggable bus like
     USB, we may later add some gpiochip_try_remove() call, but for the
     cases we have now, return values are moot.

   - Some incremental refactoring of the gpiolib core and ACPI GPIO
     library for more descriptor usage.

   - Refactor the chained IRQ handler set-up method to handle also
     threaded, nested interrupts and set up the parent IRQ correctly.
     Switch STMPE and TC3589x drivers to use this registration method.

   - Add a .irq_not_threaded flag to the struct gpio_chip, so that also
     GPIO expanders that block but are still not using threaded IRQ
     handlers.

   - New drivers for the ARM64 X-Gene SoC GPIO controller.

   - The syscon GPIO driver has been improved to handle the "DSP GPIO"
     found on the TI Keystone 2 SoC:s.

   - ADNP driver switched to use gpiolib irqchip helpers.

   - Refactor the DWAPB driver to support being instantiated from and
     MFD cell (platform device).

   - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP,

Pull networking updates from David Miller:
 "Most notable changes in here:

   1) By far the biggest accomplishment, thanks to a large range of
      contributors, is the addition of multi-send for transmit.  This is
      the result of discussions back in Chicago, and the hard work of
      several individuals.

      Now, when the ->ndo_start_xmit() method of a driver sees
      skb->xmit_more as true, it can choose to defer the doorbell
      telling the driver to start processing the new TX queue entires.

      skb->xmit_more means that the generic networking is guaranteed to
      call the driver immediately with another SKB to send.

      There is logic added to the qdisc layer to dequeue multiple
      packets at a time, and the handling mis-predicted offloads in
      software is now done with no locks held.

      Finally, pktgen is extended to have a "burst" parameter that can
      be used to test a multi-send implementation.

      Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
      virtio_net

      Adding support is almost trivial, so export more drivers to
      support this optimization soon.

      I want to thank, in no particular or implied order, Jesper
      Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
      Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
      David Tat, Hannes Frederic Sowa, and Rusty Russell.

   2) PTP and timestamping support in bnx2x, from Michal Kalderon.

   3) Allow adjusting the rx_copybreak threshold for a driver via
      ethtool, and add rx_copybreak support to enic driver.  From
      Govindarajulu Varadarajan.

   4) Significant enhancements to the generic PHY layer and the bcm7xxx
      driver in particular (EEE support, auto power down, etc.) from
      Florian Fainelli.

   5) Allow raw buffers to be used for flow dissection, allowing drivers
      to determine the optimal "linear pull" size for devices that DMA
      into pools of pages.  The objective is to get exactly the
      necessary amount of headers into the linear SKB area pre-pulled,
      but no more.  The new interface drivers use is eth_get_headlen().
      From WANG Cong, with driver conversions (several had their own
      by-hand duplicated implementations) by Alexander Duyck and Eric
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   8) eBPF now can load programs via a system call and has an extensive
      testsuite.  Alexei Starovoitov and Daniel Borkmann.

   9) Major overhaul of the packet scheduler to use RCU in several major
      areas such as the classifiers and rate estimators.  From John
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  12) Add Datacenter TCP congestion control algorithm support, From
      Florian Westphal.

  13) Reorganize sk_buff so that __copy_skb_header() is significantly
      faster.  From Eric Dumazet"

d5935b07da ARM64: SoC changes for 3.18 
Starting with 3.18, we are merging SoC-specific changes for arm64 through
 the arm-soc tree, like we have been doing for arm32.
 
 This time, there is only one set of changes, adding support for the
 Cavium "Thunder" Soc family. Since the changes are relatively small,
 this includes Kconfig, defconfig and DT changes.
 
 If all goes well, we will never require adding actual C source code
 for platform support in arm64, given that the architecture is more
 clearly defined and we have moved out a lot of the platform specifics
 into device drivers for arm32 already.

8b45bc892e ARM: SoC driver updates for 3.18 
These are changes for drivers that are intimately tied to some SoC
 and for some reason could not get merged through the respective
 subsystem maintainer tree.
 
 Most of the new code is for the Keystone Navigator driver, which is
 new base support that is going to be needed for their hardware
 accelerated network driver and other units.
 
 Most of the commits are for moving old code around from at91 and omap
 for things that are done in device drivers nowadays.
 
 - at91: move reset, poweroff, memory and clocksource code into drivers
   directories
 - socfpga: add edac driver (through arm-soc, as requested by Boris)
 - omap: move omap-intc code to drivers/irqchip
 - sunxi: added an RTC driver for sun6i
