      Merge tag 'iio-for-4.5a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

      First set of new device support, features and cleanups for IIO in the 4.5 cycle
      
      Usual mixed bag, but the big item perhaps in this series is the DMA buffer
      support added by Lars-Peter Clausen. It's been in the works for a long time
      and it will be interesting to see what hardware support shows up now that
      this is available.
      
      New core features + associate cleanup.
      * Add generic DMA buffer infrastructure
      * Add a DMAengine framework based buffer
       Also associated minor changes.
         - Set the device buffer watermark based on the minimum watermark for all
           attached buffers rather than just the 'primary' one.
         - iio_buffer_init - only set the watermark default if one hasn't already
           been provided.  This allows simple support for devices with a fixed
           watermark.
         - read only attribute for watermark on fixed watermark devices.
         - add explicit buffer enable/disable callbacks to allow the buffer to
           do more than trivial actions when it is being turned on and off.
      * IIO_VAL_INT support in write_raw_get_fmt function.
      
      New device support
      * Freescale MMA7455/7456L accelerometers
      * Memsic MXC6255XC accelerometer
      * ST lis2dh12 accelerometer
      * TI ADS8688 ADC
      * TI Palamas (twl6035/7) gpadc
      
      New driver features
      * mma8452
        - support either of the available interrupt pins to cope with the case
          where board layout has lead to a particular one being connected.
      
      Staging graduation
      * Dummy driver
        - this driver acts as both an example and a test device for those with
          out hardware to develop userspace code against.
      
      Cleanups and minor bits and bobs.
      * treewide
        - Sort out the ordering of iio_device_register/unregister vs runtime
          pm function calls so that it's all nice and consistent and not race
          prone.
        - Check sscanf return values.  None of the cases will actually happen as
          the strings are supplied internally, but best to be consistent on this.
      * ad7780
        - switch over to the gpio descriptor interface and remove the now unused
          platform data which gets rid of a header entirely.
      * ad7793
        - drop a pointless else statement.
      * at91_adc
        - Swap kmalloc_array in for a kmalloc doing the same job.
      * dummy
        - get rid of some commented out lines that snuck in during the move of
          the driver.
      * lm3533-als
        - Print an error message on provision of an invalid resistance.
      * mcp320x
        - Add compatible strings with vendor prefix and deprecate those with
          no vendor prefix.
      * mxs-lradc
        - Use BIT macro in various places rather than shifted ones.
      * pa12203001
        - Power off the chip if the registration fails.
      * pulsedlight-lidar-lite
        - add runtime PM support.
      * xilinx XADC
        - constify an iio_buffer_setup_ops structure.

      Merge slub bulk allocator updates from Andrew Morton:
       "This missed the merge window because I was waiting for some repairs to
        come in.  Nothing actually uses the bulk allocator yet and the changes
        to other code paths are pretty small.  And the net guys are waiting
        for this so they can start merging the client code"
      
      More comments from Jesper Dangaard Brouer:
       "The kmem_cache_alloc_bulk() call, in mm/slub.c, were included in
        previous kernel.  The present version contains a bug.  Vladimir
        Davydov noticed it contained a bug, when kernel is compiled with
        CONFIG_MEMCG_KMEM (see commit 03ec0ed5: "slub: fix kmem cgroup
        bug in kmem_cache_alloc_bulk").  Plus the mem cgroup counterpart in
        kmem_cache_free_bulk() were missing (see commit 03374518 "slub:
        add missing kmem cgroup support to kmem_cache_free_bulk").
      
        I don't consider the fix stable-material because there are no in-tree
        users of the API.
      
        But with known bugs (for memcg) I cannot start using the API in the
        net-tree"

        slab/slub: adjust kmem_cache_alloc_bulk API
        slub: add missing kmem cgroup support to kmem_cache_free_bulk
        slub: fix kmem cgroup bug in kmem_cache_alloc_bulk
