Merge tag 'drm-next-2019-05-09' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.
There are also some rcar-du patches which crossover with media tree
but all should be acked by Mauro.
Summary:
uapi changes:
- Colorspace connector property
- fourcc - new YUV formts
- timeline sync objects initially merged
- expose FB_DAMAGE_CLIPS to atomic userspace
new drivers:
- vboxvideo: moved out of staging

- devm device init
- MIPI/DSI rate control
- shmem backed gem objects
- connector, display_info, edid_quirks cleanups
- dma_buf fence chain support
- 64-bit dma-fence seqno comparison fixes
- move initial fb config code to core
- gem fence array helpers for Lima
- ability to remove legacy support code if no drivers requires it (removes 10% of drm.ko size)
- lease fixes
