Subject: [PATCH] drm/vc4: UV planes vertical scaling must always be enabled
|
|
|
|
It has been observed that a YUV422 unity scaled plane isn't displayed.
|
|
Enabling vertical scaling on the UV planes solves this. There is
|
|
already a similar clause to always enable horizontal scaling on the
|
|
UV planes.
