Comment 1 Imre Deak 2016-07-11 13:29:12 UTC 
Are you using an APL RVP? In that case I suggested closing this, since without LSPCON support in the driver it's expected that you won't have a working HDMI output.
Comment 2 Luis Botello 2016-10-14 20:13:46 UTC 
Yes, we still have an APL RVP Fab2 and hot plug events are working fine but hotplug after S3 still is not working. 
So, I guess we can close this.

Closing based on comment #1 and comment #2
