As you suggest, since the DP-PHY driver is NOT yet in mainline, we may
have to keep this patch reverted till your patch series gets merged to

I tested the patch before sending on Exynos5250-SMDK5250 using Kishon
Vijay Abraham's series at http://lwn.net/Articles/559487/
which contains DP-PHY driver posted by you
1. phy: Add driver for Exynos DP PHY
2. video: exynos_dp: remove non-DT support for Exynos Display Port
3. video: exynos_dp: Use the generic PHY driver
