Subject: [PATCH] drm/vc4: plane: Create overlays for any CRTC
|
|
|
|
Now that we have everything in place, we can now register all the overlay
|
|
planes that can be assigned to all the CRTCs.
|
|
|
|
This has two side effects:
|
|
|
|
- The number of overlay planes is reduced from 24 to 8. This is temporary
|
|
and will be increased again in the next patch.
|
|
|
|
- The ID of the various planes is changed again, and we will now have all
|
|
the primary planes, then all the overlay planes and finally the cursor
|
|
planes. This shouldn't cause any issue since the ordering between
|
|
primary, overlay and cursor planes is preserved.
