From: Joonyoung Shim Date: Wed, 27 Jun 2012 05:27:04 +0000 (+0900) Subject: drm/exynos: use private plane for crtc X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b5d2eb3bd691c0b6869a2013e719a61c595d73a6;p=openwrt%2Fstaging%2Fblogic.git drm/exynos: use private plane for crtc The crtc can use private plane instead it has overlay struct. It will be helpful use plane feature from crtc later.
