Summary
We covered the platform: BSW, Broadwell, Baytrail-M, Haswell, Ivybridge, SandyBridge, IronLake.
We involved BSW first time. Basically HDMI/DP works, and eDP doesn't works for a regression issue.

In this circle, 5 new bugs are filed.
Bug 84320<https://bugs.freedesktop.org/show_bug.cgi?id=84320> - [BDW Regression]HDMI hotplut cause CallTrace
Bug 84310<https://bugs.freedesktop.org/show_bug.cgi?id=84310> - [BDW]Black screen shows while executing xrandr rotation
Bug 84265<https://bugs.freedesktop.org/show_bug.cgi?id=84265> - [BSW Regression]System fails to find eDP monitor.
Bug 84303<https://bugs.freedesktop.org/show_bug.cgi?id=84303> - [BSW]Monitor losts signal on some interlaced resolutions.
Bug 84304<https://bugs.freedesktop.org/show_bug.cgi?id=84304> - [BSW]Monitor is black screen with backlight on some HDMI resolutions.
