This patch is based on exynos-drm-next branch of Inki Dae's tree at: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git DECON(Display and Enhancement Controller) is the new IP in exynos7 SOC for generating video signals using pixel data. DECON driver can be used to drive 2 different interfaces on Exynos7: DECON-INT(video controller) and DECON-EXT(Mixer for HDMI) The existing FIMD driver code was used as a template to create DECON driver. Only DECON-INT is supported as of now, and DECON-EXT support will be added later. The current version of the driver supports video mode displays. Changelog v2: - Change config name, DRM_EXYNOS_DECON to DRM_EXYNOS7_DECON.
