Subject: [PATCH] drm: vc4-firmware-kms: Remove incorrect overscan
|
||
|
|
support.
|
||
|
|
|
||
|
|
The overscan support was required for the old mailbox API
|
||
|
|
in order to match up the cursor and frame buffer planes.
|
||
|
|
With the newer API directly talking to dispmanx there is no
|
||
|
|
difference, therefore FKMS does not need to make any
|
||
|
|
adjustments.

||
