Subject: [PATCH] drm/atomic: If margins are updated, update all
|
|
planes.
|
|
|
|
Margins may be implemented by scaling the planes, but as there
|
|
is no way of intercepting the set_property for a standard property,
|
|
and all planes are checked in drm_atomic_check_only before the
|
|
connectors, there's now way to add the planes into the state
|
|
from the driver.
|
|
|
|
If the margin properties change, add all corresponding planes to
|
|
the state.
