Subject: [PATCH 596/697] drm/vc4: plane: Change ptr0_offset to an array
|
|
|
|
The BCM2712 will have a fairly different dlist, that will feature one
|
|
Pointer 0 word for each plane.
|
|
|
|
Let's prepare by changing the ptr0_offset variable that holds the offset
|
|
in a dlist of the pointer 0 word to an array.
