       "This contains fixes for two critical bugs in UBI and UBIFS:
      
         - fix the possibility of losing data upon a power cut when UBI tries
           to recover from a write error
      
         - fix page migration on UBIFS.  It turned out that the default page
           migration function is not suitable for UBIFS"

      Pull drm fixes from Dave Airlie:
       "This is the drm fixes tree for 4.7-rc5.
      
        It's a bit larger than normal, due to fixes for production AMD Polaris
        GPUs.  We only merged support for these in 4.7-rc1 so it would be good
        if we got all the fixes into final.  The changes don't hit any other
        hardware.
      
        Other than the amdgpu Polaris changes:
      
         - A single fix for atomic modesetting WARN
         - Nouveau fix for when fbdev is disabled
         - i915 fixes for FBC on Haswell and displayport regression
         - Exynos fix for a display panel regression and some other minor changes
         - Atmel fixes for scaling and OF graph interaction
         - Allwiinner build, warning and probing fixes
         - AMD GPU non-polaris fix for num_rbs and some minor fixes
      
        Also I've just moved house, and my new place is Internet challenged
        due to incompetent incumbent ISPs, hopefully sorted out in a couple of
        weeks, so I might not be too responsive over the next while.  It also
        helps Daniel is on holidays for those couple of weeks as well"

      Pull PCI fix from Bjorn Helgaas:
       "Here's a small fix for v4.7.  This problem was actually introduced in
        v4.6 when we unified Kconfig, making PCIe support available everywhere
        including sparc, where config reads into unaligned buffers cause
        warnings.  This fix is from Dave Miller.
      
        As a reminder, any future PCI fixes for v4.7 will probably come from
        Alex Williamson, since I'll be on vacation for most of the rest of
        this cycle.  I should be back about the time the merge window opens"

      A bit bigger than I would normally like, but most of the large changes are
      for polaris support and since polaris went upstream in 4.7, I'd like
      to get the fixes in so it's in good shape when the hw becomes available.
      The major changes only touch the polaris code so there is little chance
      for regressions on other asics.  The rest are just the usual collection
      of bug fixes.

      Since HW trigger mode was suppoted we have faced with a issue
      that Display panel didn't work correctly when trigger mode was changed
      in booting time.
      For this, we keep trigger mode with SW trigger mode in default mode
      like we did before.
      
      However, we will need to consider PSR(Panel Self Reflash) mode to resolve
      this issue fundamentally later.
