From 2eeb2e5e6634dbb97bdda81f65f70e4b037028d5 Mon Sep 17 00:00:00 2001 From: Gustavo Padovan Date: Mon, 3 Aug 2015 14:40:44 +0900 Subject: [PATCH] drm/exynos: use drm atomic state directly For some fields the use of struct exynos_drm_plane filled with data from the plane state just creates a source of duplicated information and overhead. Here we change the crtc drivers to access the plane state directly simplifying the code by not relying on a exynos internal struct.
