Moves the properties of DP controller to exynos5.dtsi which are common across exynos5 SoCs like Exynos5250 and Exynos5420.
The PHY DP Node is based on Jingoo Han's jg1.han@samsung.com patch at https://patchwork.linuxtv.org/patch/19189/

This patch should be reverted. Or, fix patch should be re-sent. 'dp phy' driver is not yet merged to mainline kernel.
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 have DP working on exynos5 .
OK, got it. Please send patch fixing this issue for v3.12. Of course, we need this from v3.13 which will be including the DP-PHY driver.
Thanks, Kukjin

Vikas Sajjan, Please test your patch on real boards when you send your patch.
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
