Commit 60a10650 authored by Dave Airlie's avatar Dave Airlie

Merge tag 'drm-msm-fixes-2020-08-24' of https://gitlab.freedesktop.org/drm/msm into drm-fixes

Some fixes for v5.9 plus the one opp/bandwidth scaling patch ("drm:
msm: a6xx: use dev_pm_opp_set_bw to scale DDR") which was not included
in the initial pull due to dependency on patch landing thru OPP tree
