Merge tag 'drm-next-2020-06-02' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie:
"Highlights:
- Core DRM had a lot of refactoring around managed drm resources to
make drivers simpler.
- Intel Tigerlake support is on by default
- amdgpu now support p2p PCI buffer sharing and encrypted GPU memory
Details:
core:
- uapi: error out EBUSY when existing master
- uapi: rework SET/DROP MASTER permission handling
- remove drm_pci.h
- drm_pci* are now legacy
- introduced managed DRM resources
- subclassing support for drm_framebuffer
- simple encoder helper
- edid improvements
- vblank + writeback documentation improved
- drm/mm - optimise tree searches
- port drivers to use devm_drm_dev_alloc
dma-buf:
- add flag for p2p buffer support
mst:
- ACT timeout improvements
- remove drm_dp_mst_has_audio
- don't use 2nd TX slot - spec recommends against it
bridge:
- dw-hdmi various improvements
- chrontel ch7033 support
- fix stack issues with old gcc
hdmi:
- add unpack function for drm infoframe
fbdev:
- misc fbdev driver fixes
i915:
- uapi: global sseu pinning
- uapi: OA buffer polling
- uapi: remove generated perf code
- uapi: per-engine default property values in sysfs
- Tigerlake GEN12 enabled.
- Lots of gem refactoring
- Tigerlake enablement patches
- move to drm_device logging
- Icelake gamma HW readout
- push MST link retrain to hotplug work
- bandwidth atomic helpers
- ICL fixes
- RPS/GT refactoring
- Cherryview full-ppgtt support

radeon:
- safe reg list generator fixes
nouveau:
- HD audio fixes on recent systems
- vGPU detection (fail probe if we're on one, for now)
