What are the consequences to change the interrupt parent?

I am not entirely sure about it at the moment but looks like it
controllers power domain
for various devices like GPU, VPU and OTG etc.

So, we may not be able to support these devices for XEN domains ?

I haven't used the platform so I can't for sure know what can happen here. The risk is if all the power domains are turned off at boot, then Dom0 would not be able to turn them on. Therefore all the devices you listed may be unusable.
