Hi Jacopo,

Depending on how we interpret the data-active property this can be good 
or bad. But if we interpret it as the polarity of the VIn_CLKENB pin 
this is not good as this is not connected for the adv7180 on Koelsch.

I have not checked all the Gen2 schematics as I'm still not sure how to 
interpret the property.
