Merge branch 'drm-next-4.19' of git://people.freedesktop.org/~agd5f/linux into drm-next
First feature request for 4.19. Highlights: - Add initial amdgpu documentation - Add initial GPU scheduler documention - GPU scheduler fixes for dying processes - Add support for the JPEG engine on VCN - Switch CI to use powerplay by default - EDC support for CZ - More powerplay cleanups - Misc DC fixes Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180621161138.3008-1-alexander.deucher@amd.com
