       "Clean up the clock API on legacy SH to make it more similar to the
        Common Clock Framework.  This will avoid different behaviour in
        drivers shared between legacy and CCF-based platforms (e.g.  SCIF)"

      Pull ARM SoC driver updates from Olof Johansson:
       "Driver updates for ARM SoCs.  Some for SoC-family code under
        drivers/soc, but also some other driver updates that don't belong
        anywhere else.  We also bring in the drivers/reset code through
        arm-soc.
      
        Some of the larger updates:
      
         - Qualcomm support for SMEM, SMSM, SMP2P.  All used to communicate
           with other parts of the chip/board on these platforms, all
           proprietary protocols that don't fit into other subsystems and live
           in drivers/soc for now.
      
         - System bus driver for UniPhier
      
         - Driver for the TI Wakeup M3 IPC device
      
         - Power management for Raspberry PI
      
        + Again a bunch of other smaller updates and patches"

      Pull ARM SoC defconfig updates from Olof Johansson:
       "As usual, a bunch of commits, mostly adding drivers and other options
        to defconfigs because it makes sense to have them enabled on various
        development or product boards.  Too much to enumerate each here.
      
        There's an introduction of a pxa_defconfig, since PXA finally will
        allow building a shared kernel for all boards.  With this, we can
        hopefully remove a bunch of individual defconfigs down the road but it
        requires a bit of real life testing and transition period"

      Pull ARM SoC multiplatform code updates from Arnd Bergmann:
       "This branch is the culmination of 5 years of effort to bring the ARMv6
        and ARMv7 platforms together such that they can all be enabled and
        boot the same kernel.  It has been a tremendous amount of cleanup and
        refactoring by a huge number of people, and creation of several new
        (and major) subsystems to better abstract out all the platform details
        in an appropriate manner.
      
        The bulk of this branch is a large patchset from Arnd that brings
        several of the more minor and older platforms we have closer to
        multiplatform support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0
        and realview Much of this is moving around header files from old mach
        directories, but there are also some cleanup patches of debug_ll
        (lowlevel debug per-platform options) and other parts.
      
        Linus Walleij also has some patchs to clean up the older ARM Realview
        platforms by finally introducing DT support, and Rob Herring has some
        for ARM Versatile which is now DT-only.  Both of these platforms are
        now multiplatform.
      
        Finally, a couple of patches from Russell for Dove PMU, and a fix from
        Valentin Rothberg for Exynos ADC, which were rebased on top of the
        series to avoid conflicts"

       "The asm-generic tree this time contains one series from Nicolas Pitre
        that makes the optimized do_div() implementation from the ARM
        architecture available to all architectures.
      
        This also adds stricter type checking for callers of do_div, which has
        uncovered a number of bugs in existing code, and fixes up the ones we
        have found"

       "The highlights this round include:
      
         - Introduce configfs support for unlocked configfs_depend_item()

      Do not enable CONFIG_IO_STRICT_DEVMEM by default · 19a3dd76
      Dan Williams authored
      Larry Finger reports:
       "My PowerBook G4 Aluminum with a 32-bit PPC processor fails to boot for
        the 4.4-git series".
      
      This is likely due to X still needing /dev/mem access on this platform.
      
      CONFIG_IO_STRICT_DEVMEM is not yet safe to turn on when
      CONFIG_STRICT_DEVMEM=y.
      
      Remove the default so that old configurations do not change behavior.
      
      Fixes: 90a545e9 ("restrict /dev/mem to idle io memory ranges")
