on my eDP panel with gpio-hotplug via the dp-connector as before, I get
a successful display output even on boot.
- plugged in on boot - display works / reported as connected
- plugged out - correctly reported as disconnected
- plugged in again - display works / reported as connected
- unplugged on boot - correctly reported as disconnected
- plugged in - display works / reported as connected
Multiple plugin/plugout operations afterwards also worked nicely.
So

Will do reviewing of patches now ;-)
Thanks for working on that
Heiko
