Subject: [PATCH 0616/1085] drm/vc4: txp: Add horizontal and vertical size
|
|
offset toggle bit
|
|
|
|
The new writeback controllers that can be found on the BCM2712 require
|
|
to have their horizontal and vertical size reduced by one.
|
|
|
|
Let's tie that behaviour to the compatible so we can support both the
|
|
new and old controllers.
