How does this block relate to the capture block? I separated them because the current legacy drivers are separated into 3 different platform drivers. However, after some discussions with Laurent, I'm going to just create a single VPIF node with input (capture) and output (display) ports, and then have to tweak the existing drivers a bit more than I had wanted to. IOW, I was lazy.
