We are using Jetson TX2 and a custom carrier board. We are working on enabling DSI, the documentation is a bit confusing and is basically because there is a different naming convention for port’s name in the module and in the carrier board.
The module as you can see in Figure 12 in  has output ports A, B, C and D, each of 2 MIPI DSI Lanes. However, the Display connector on the module has only 2 ports A and B of 4 MIPI DSI Lanes each.
Checking the datasheet for TX2  on page 30, it says that Jetson TX2 can only be used on dual 4 MIPI DSI Lanes (Ports A x4MIPI DSI and Port C x4MIPI DSI) or one big single 8 MIPI DSI port.
In this case, is it correct to assume that if I want to use Port A in 2 MIPI DSI Lane mode (not 4 DSI Lanes) it is not possible? correct? is 4 MIPI DSI Lanes the only way to use it?
