Kukjin,

This patch is -rc material and is needed to have display working in
3.18 again since commit a5ec598 ("phy: exynos-dp-video: Use syscon
support to control pmu register") landed in 3.18 and broke the Exynos
Display Port PHY:

exynos-dp-video-phy 10040728.video-phy: Failed to lookup PMU regmap

Best regards,
Javier
