Comment 1 wendy.wang 2014-10-24 06:19:20 UTC 
Re-verify the HDMI function on both BSW RVP fab1 and fab2 board, with latest drm-intel-nightly branch kernel:
2014_10_24/drm-intel-nightly/6f628cbf2f18ac47e8afad50e3c328bbc33754d2

Below scenarios are all working:
1. Boot with edp and HDMI together, after start kernel, both edp and HDMI show screen correctly

2. Boot with edp panel, power on the machine, hotplug HDMI monitor, both edp and HDMI show screen correctly

so close this bug.
