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
- drm_device.irq_enabled removed
- port drivers to native irq interfaces
- export gem shadow plane handling for vgem
- print proper driver name in framebuffer registration
- driver fixes for implicit fencing rules
- ARM fixed rate compression modifier added
- updated fb damage handling
- rmfb ioctl logging/docs
- drop drm_gem_object_put_locked
- define DRM_FORMAT_MAX_PLANES
- add gem fb vmap/vunmap helpers
- add lockdep_assert(once) helpers
- mark drm irq midlayer as legacy
- use offset adjusted bo mapping conversion
