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
Tested-by: Heiko Stuebner <heiko@sntech.de>

Will do reviewing of patches now ;-)


Thanks for working on that
Heiko
