Which seems correct, given that the vcodec-lat-soc doesn't have an interrupt [1]. So I guess this is just the generic video-codec node in the binding being too generic for some cases. Ideally we would override interrupts to be required based on which subnode we're dealing with (for lat and core, but not lat-soc), but given these are subnodes matched through patternProperties, I'm not sure that would be possible.
