This belongs below the '---' and probably means you should send all this 
as one series.

We already have a standard property for this. Use it. 

It belongs in the connector node as HPD is part of the connector.

Note that this too should be in a connector node.

Thanks Rob for reviews.

We are using Display Port Controller block to detect hot plug.
So we won't be using that pin as GPIO.

I found now that we don't need any bindings for that pin in such case.
So I am abandoning this patch series and upload new patch.

Thanks.
