do you have this in your dmesg?
...
exynos-dp-video-phy 10040728.video-phy: Failed to lookup PMU regmap
...
to get a working framebuffer out of linus 318rc4 on my peach pi, i had
to cherry pick these 3 patches:
arm: dts: Exynos5: Use pmu_system_controller phandle for dp phy
drm/exynos: dp: Remove support for unused dptx-phy
ARM: exynos_defconfig: Enable options for display panel support
Check if you have those.
