What's the difference between them? I understand parent device is entire
block of consisting of multiple processing units? If so, video-codec
actually could fit in both places. But feel free to call it a bit
different (video-codec-core, video-codec-lat, processing-unit, even
something less generic). Sometimes it's tricky to find nice name, so I
wouldn't worry too much in that case. Just not "mt8192-vcodec" :)
