To be clearer, the IP itself does support 2 streams going to two
different pipes in parallel but we never had a validation platform for
Atom gizmos with two connectors and no use case for tablets/phone.
Never say never as usual, now we see CHT mini-PC devices with 2
connectors, either both DP or DP+HDMI so we'll have to see how things go
when both are enabled. It's on the TODO list.
