From: Laurent Pinchart Date: Tue, 7 Jun 2022 16:33:22 +0000 (+0300) Subject: drm: rcar-du: Lift z-pos restriction on primary plane for Gen3 X-Git-Tag: v6.6.17~6802^2~6^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=676ad8e997036e2f815c293b76c356fb7cc97a08;p=platform%2Fkernel%2Flinux-rpi.git drm: rcar-du: Lift z-pos restriction on primary plane for Gen3 There's no reason to require the primary plane to always be at the bottom of the stack, as the VSP supports arbitrary ordering of planes, and the KMS API doesn't have such a requirement either. Lift the restriction. As the primary plane can now be positioned arbitrarily, enable control of its alpha channel as well.
