From ae56bfbdad9b1996037a7209321cfb2ef49ea563 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Fri, 23 Nov 2018 10:24:46 +0100 Subject: drm/sun4i: backend: Avoid counting YUV planes that use the frontend Our hardware has a limited number of YUV planes (usually 1) that can be supported using the backend only. However, YUV planes can also be supported by the frontend and must then not be counted when checking for that limitation. Only count the YUV plane when the frontend is not used.
