This change itself is OK, but this made me wonder about the driver implementation: the current MAX_PB=1 is the hardware limitation or the soft limitation? That is, can't we play back two streams when we connect two HDMI monitors?
Two streams was never validated from hardware per se. So setting the limitation in software.
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.
