7.4.20.2 Example 2:

The DS90UB954-Q1 is receiving two video streams from sensors on each input port. Each sensor is sending video streams using VC-IDs 0 and 1. Receive Port 0 maps the VC-IDs directly without change. Receive Port 1 maps the VC-IDs 0 and 1 to VC-IDs 2 and 3. This is required because each CSI-2 transmitter is limited to 4 VC-IDs per MIPI specification.
