Subject: drm/amd/display: reprogram surface config on scaling change
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f8668c099e71bdd2c4e8bfd3d79178e243a99835;p=linux.git

drm/amd/display: reprogram surface config on scaling change

When plane size changes, we need to reprogram surface pitch in addition
to viewport and scaler. This change is a conservative way to make this happen.
However it could be more optimized to move pitch programming into
mem_program_viewport.
