      ide: replace strict_strtol() with kstrtol() · 79c8fa0b
      Jingoo Han authored
      The usage of strict_strtol() is not preferred, because
      strict_strtol() is obsolete. Thus, kstrtol() should be
      used.

      Linus Torvalds authored
      Pull drm tree changes from Dave Airlie:
       "This is the main drm pull request, I have some overlap with sound and
        arm-soc, the sound patch is acked and may conflict based on -next
        reports but should be a trivial fixup, which I'll leave to you!
      
        Highlights:
      
         - new drivers:
      
           MSM driver from Rob Clark
      
         - non-drm:
      
           switcheroo and hdmi audio driver support for secondary GPU
           poweroff, so drivers can use runtime PM to poweroff the GPUs.  This
           can save 5 or 6W on some optimus laptops.
      
         - drm core:
      
           combined GEM and TTM VMA manager
           per-filp mmap permission tracking
           initial rendernode support (via a runtime enable for now, until we get api stable),
           remove old proc support,
           lots of cleanups of legacy code
           hdmi vendor infoframes and 4k modes
           lots of gem/prime locking and races fixes
           async pageflip scaffolding
           drm bridge objects
      
         - i915:
      
           Haswell PC8+ support and eLLC support, HDMI 4K support, initial
           per-process VMA pieces, watermark reworks, convert to generic hdmi
           infoframes, encoder reworking, fastboot support,
      
         - radeon:
      
           CIK PM support, remove 3d blit code in favour of DMA engines,
           Berlin GPU support, HDMI audio fixes
      
         - nouveau:
      
           secondary GPU power down support for optimus laptops, lots of
           fixes, use MSI, VP3 engine support
      
         - exynos:
      
           runtime pm support for g2d, DT support, remove non-DT,
      
         - tda998x i2c driver:
      
           lots of fixes for sync issues
      
         - gma500:
      
           lots of cleanups
      
         - rcar:
      
           add LVDS support, fbdev emulation,
      
         - tegra:
      
           just minor fixes"

      Pull OMAP specific fbdev changes from Tomi Valkeinen:
       "I've got this pull request separate from the main fbdev pull request,
        as this contains a bunch of OMAP board file changes and thus could
        possibly be rejected in case of bad conflicts.
      
        The removal of the old display drivers depend on the board file
        changes, so Tony Lindgren suggested taking them together via fbdev
        tree.  These are in linux-next, and also Tony didn't see any conflicts
        with any of the branches he had, so they should go in clean.
      
         - Change the OMAP board files to use the new OMAP display drivers
      
         - Remove all the old drivers, and the related auxiliary code"

      connected via a special bus and listed in the firmware device tree.
      This change adds support for these BMCs to the IPMI driver.

      The latest versions of the kernel drivers for ipmi can use ACPI to
      determine the type of BMC device used in the system.  The following

      This patch fixes wrong pixel format setting.
      
      A pixel format is decided according to bpp and depth, or user-requested
      format but fimd driver considered only bpp value to decide a proper pixel
      format. So this patch makes a proper pixel format to be set according
      to drm_framebuffer's pixel_format which is set by addfb with bpp and
      depth, or addfb2 with user-requested format.

      drm/exynos: add device tree support for rotator · 319477f3
      Chanho Park authored
      The exynos4 platform is only dt-based since 3.10, we should convert driver data
      and ids to dt-based parsing methods. The rotator driver has a limit table to get
      size limit of input picture. Each SoCs has slightly different limit value
      compared with any others.
      For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have
      8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size
      for its X/Y axis. Thus, we should keep different tables for each of them.
      This patch also includes desciptions of each nodes for the rotator and specifies
      a example how to bind it.
