Merge tag 'drm-msm-next-2019-11-05' of https://gitlab.freedesktop.org/drm/msm into drm-next
+ OCMEM support to enable the couple generations that had shared OCMEM rather than GMEM exclusively for the GPU (late a3xx and I think basically all of a4xx). Bjorn and Brian decided to land this through the drm tree to avoid having to coordinate merge requests. + a510 support, and various associated display support + the usual misc cleanups and fixes Signed-off-by: Dave Airlie <airlied@redhat.com> From: Rob Clark <robdclark@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/ <CAF6AEGv-JWswEJRxe5AmnGQO1SZnpxK05kO1E29K6UUzC9GMMw@mail.gmail.com
