+ can output two RAW12 packed data streams. One is IR and the other is Depth.
+ Each data stream is on a separate or same MIPI Virtual Channel, depending
+ on configuration and each have 640x480 resolution.

If, as we discussed, the hardware does not support one lane operation (or
other lane configurations I presume), you don't need data-lanes property.
