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

		title: DisplayPort AUX bus

		maintainers:
		- Douglas Anderson <dianders@chromium.org>

		description:
		DisplayPort controllers provide a control channel to the sinks that
		are hooked up to them. This is the DP AUX bus. Over the DP AUX bus
		we can query properties about a sink and also configure it. In
		particular, DP sinks support DDC over DP AUX which allows tunneling
		a standard I2C DDC connection over the AUX channel.

		To model this relationship, DP sinks should be placed as children
		of the DP controller under the "aux-bus" node.

		At the moment, this binding only handles the eDP case. It is
		possible it will be extended in the future to handle the DP case.
		For DP, presumably a connector would be listed under the DP AUX
		bus instead of a panel.
