Thank you for your kind assistance, I have created a tree which checkout 
from the next-20151019. Surely there were some conflicts to applied this 
series on that tag, but things still works for me, here is the git 
address [https://github.com/yakir-Yang/linux/tree/analogix_dp]

Best regards,

I tested your branch on an Exynos5800 Peach Pi Chromebook and display is
working on boot. I also tested DPMS and S2R and things are still working
so for the whole series feel free to add:
