Merge tag 'drm-next-2021-08-31-1' of git://anongit.freedesktop.org/drm/drm

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:

-	help
-	  Firmwares often provide initial graphics framebuffers so the BIOS,
-	  bootloader or kernel can show basic video-output during boot for
-	  user-guidance and debugging. Historically, x86 used the VESA BIOS
-	  Extensions and EFI-framebuffers for this, which are mostly limited
-	  to x86.
-	  This option, if enabled, marks VGA/VBE/EFI framebuffers as generic
-	  framebuffers so the new generic system-framebuffer drivers can be
-	  used on x86. If the framebuffer is not compatible with the generic
-	  modes, it is advertised as fallback platform framebuffer so legacy
-	  drivers like efifb, vesafb and uvesafb can pick it up.
-	  If this option is not selected, all system framebuffers are always
-	  marked as fallback platform framebuffers as usual.
-
-	  Note: Legacy fbdev drivers, including vesafb, efifb, uvesafb, will
-	  not be able to pick up generic system framebuffers if this option
-	  is selected. You are highly encouraged to enable simplefb as
-	  replacement if you select this option. simplefb can correctly deal
-	  with generic system framebuffers. But you should still keep vesafb
-	  and others enabled as fallback if a system framebuffer is
-	  incompatible with simplefb.
-
-	  If unsure, say Y.
