Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

  core:
   - extract i915 eDP backlight into core
   - DP aux bus support

+	 * - Similarly drivers must set the exclusive fence through

+	 *   write access.
+	 *
+	 * - Drivers may just always set the exclusive fence, since that only
+	 *   causes unecessarily synchronization, but no correctness issues.
+	 *
+	 * - Some drivers only expose a synchronous userspace API with no
+	 *   pipelining across drivers. These do not set any fences for their
+	 *   access. An example here is v4l.
+	 *
+	 * DYNAMIC IMPORTER RULES:
+	 *
+	 * Dynamic importers, see dma_buf_attachment_is_dynamic(), have
+	 * additional constraints on how they set up fences:
+	 *
+	 * - Dynamic importers must obey the exclusive fence and wait for it to
+	 *   signal before allowing access to the buffer's underlying storage
+	 *   through the device.
+	 *
+	 * - Dynamic importers should set fences for any access that they can't
