Subject: [PATCH] drm/vc4: Make normalize_zpos conditional on using
|
||
|
|
fkms
|
||
|
|
|
||
|
|
Eric's view was that there was no point in having zpos
|
||
|
|
support on vc4 as all the planes had the same functionality.
|
||
|
|
|
||
|
|
Can be later squashed into (and fixes):
|
||
|
|
drm/vc4: Add firmware-kms mode
|
