From 0d8071ee11734f92c33c1cc8926314c4e650622c Mon Sep 17 00:00:00 2001 From: Seung-Woo Kim Date: Tue, 24 Apr 2012 18:43:10 +0900 Subject: [PATCH] drm/exynos: added source size to overlay structure Set plane has source size but exynos overlay structure did not consider it. This patch adds source size to overlay structure. For set crtc, source size is set from crtc size.
