Subject: [PATCH 581/697] drm/vc4: crtc: Force trigger of dlist update on
|
|
margins change
|
|
|
|
When the margins are changed, the dlist needs to be regenerated
|
|
with the changed updated dest regions for each of the planes.
|
|
|
|
Setting the zpos_changed flag is sufficient to trigger that
|
|
without doing a full modeset, therefore set it should the
|
|
margins be changed.
