      Merge branch 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes
      
      Summary:
      - Use generic function to get buffer count instead of specific one.
        In case of Exynos DRM, There was a special case which decides pixel
        format of a given buffer according to planer types, which is NV12M and NV12.
        However, NV12M doesn't exist in drm fourcc so it removes
        exynos_drm_format_num_buffers() specific to Exynos DRM and use a generic function,
        drm_format_num_planes() instead.
      - Allow mixer driver to support NV21 format for Video processor.
        This format was already supported but we just missed DRM_FORMAT_NV21 case
        so this patch considers the case so that Mixer driver can handle it correctly.
      - Add regression fix and some code cleanups.

      Don't pollute the dmesg with EDID read success message as an error.
      Printing as debug should be fine.

      drm/exynos: cleanup exynos_drm_plane · be083a00
      Tobias Jakobi authored
      Remove the unused fields of struct exynos_drm_plane.
      
      v2: Remove index_color as well, also unused (thanks Joonyoung).

      drm/exynos: 'win' is always unsigned · 5b1d5bc6
      Tobias Jakobi authored
      The index for the hardware layer is always >=0. Previous
      code that also used -1 as special index is now gone.
      
      Also apply this to 'ch_enabled' (decon/fimd), since the
      variable is on the same line (and is again always unsigned).

      drm/exynos: mixer: don't dump registers under spinlock · c0734fba
      Tobias Jakobi authored
      mixer_regs_dump() was called in mixer_run(), which was called
      under the register spinlock in mixer_graph_buffer() and
      vp_video_buffer().
      
      This would trigger a sysmmu pagefault with drm.debug=0xff because
      of the large delay caused by the register dumping.
      
      To keep consistency also move register dumping out of mixer_stop(),
      which is the counterpart to mixer_run().

      drm/exynos: Fix build breakage on !DRM_EXYNOS_FIMD · 48107d7b
      Krzysztof Kozlowski authored
      Disabling the CONFIG_DRM_EXYNOS_FIMD (e.g. by enabling of CONFIG_FB_S3C)
      leads to build error:
      
      drivers/built-in.o: In function `exynos_dp_dpms':
      binder.c:(.text+0xd6a840): undefined reference to `fimd_dp_clock_enable'
      binder.c:(.text+0xd6ab54): undefined reference to `fimd_dp_clock_enable'
      
      Fix this by changing direct call to fimd_dp_clock_enable() into optional
      call to exynos_drm_crtc_ops->clock_enable(). Only the DRM_EXYNOS_FIMD
      implements this op.

      drm/exynos: mixer: cleanup pixelformat handling · 7a57ca7c
      Tobias Jakobi authored
      Move the defines for the pixelformats that the mixer supports out
      of mixer_graph_buffer() to the top of the source.
      Then select the mixer pixelformat (pf) in mixer_graph_buffer() based on
      the plane's pf (and not bpp).
      Also add handling of RGB565 and XRGB1555 to the switch statement and
      exit early if the plane has an unsupported pf.
      
      Partially based on 'drm/exynos: enable/disable blend based on pixel
      format' by Gustavo Padovan <gustavo.padovan@collabora.co.uk>.
      
      v2: Use the shorter MXR_FORMAT as prefix.
      v3: Re-add ARGB8888 because of compatibility reasons
          (suggested by Joonyoung Shim).

      The video processor (VP) supports four formats: NV12, NV21 and its
      tiled variants. All these formats are bi-planar, so the buffer
      count in vp_video_buffer() is always 2.

      drm/exynos: plane: honor buffer offset for dma_addr · 5d878bdb
      Tobias Jakobi authored
      Previously we were ignoring the buffer offsets that are
      passed through the addfb2 ioctl. This didn't cause any
      major issues, since for uni-planar formats (like XRGB8888)
      userspace would most of the time just use offsets[0]=0.
      
      However with NV12 offsets[1] is very likely non-zero.
      So properly apply the offsets to our dma addresses.

      drm/exynos: fb: use drm_format_num_planes to get buffer count · d10ebb9f
      Tobias Jakobi authored
      The previous code had some special case handling for the buffer
      count in exynos_drm_format_num_buffers().
      
      This code was incorrect though, since this special case doesn't
      exist for DRM. It stemmed from the existence of the special NV12M
      V4L2 format. NV12 is a bi-planar format (separate planes for luma
      and chroma) and V4L2 differentiates between a NV12 buffer where
      luma and chroma is contiguous in memory (so no data between
      luma/chroma), and a NV12 buffer where luma and chroma have two
      explicit memory locations (which is then called NV12M).
      
      This distinction doesn't exist for DRM. A bi-planar format always
      explicitly comes with the information about its two planes (even
      if these planes should be contiguous).

      Commit c9f038a1 ("drm/i915: Don't assume primary & cursor are

      Setting the primary and cursor panes to false in
      ilk_compute_wm_parameters to false does however give the following
      errors in the kernel log and causes the screen to flicker.

      watchdog: Fix merge 'conflict' · ab992dc3
      Peter Zijlstra authored
      Two watchdog changes that came through different trees had a non
      conflicting conflict, that is, one changed the semantics of a variable
      but no actual code conflict happened. So the merge appeared fine, but
      the resulting code did not behave as expected.
      
      Commit 195daf66 ("watchdog: enable the new user interface of the
      watchdog mechanism") changes the semantics of watchdog_user_enabled,
      which thereafter is only used by the functions introduced by
      b3738d29 ("watchdog: Add watchdog enable/disable all functions").
      
      There further appears to be a distinct lack of serialization between
      setting and using watchdog_enabled, so perhaps we should wrap the
      {en,dis}able_all() things in watchdog_proc_mutex.
      
      This patch fixes a s2r failure reported by Michal; which I cannot
      readily explain. But this does make the code internally consistent
      again.

         - updates to the files that belong to Marvell mvebu
      
        Bug fixes:
      
         - The largest changes are on omap2, but are only to avoid some
           harmless warnings and to fix reset on omap4
      
         - a small regression fix on tegra
      
         - multiple fixes for incorrect IRQ affinity on vexpress
      
         - the missing system controller on arm64 juno is added
      
         - one revert of a patch that was accidentally applied twice for
           mach-rockchip
      
         - two clock related DT fixes for mvebu
      
         - a workaround for suspend with old DT binaries on new exynos kernels
      
         - Another fix for suspend on exynos, needs to be backported"

      Pull thermal fixes from Zhang Rui:
       "Specifics:
      
         - fix an issue in intel_powerclamp driver that idle injection target
           is not accurately maintained on newer Intel CPUs.  Package C8 to
           C10 states are introduced on these CPUs but they were not included
           in the package c-state residency calculation.  From Jacob Pan.
      
         - fix a problem that package c-state idle injection was missing on
           Broadwell server, by adding its id to intel_powerclamp driver.
           From Jacob Pan.
      
         - a couple of small fixes and cleanups from Joe Perches, Mathias
           Krause, Dan Carpenter and Anand Moon"
