CSI num_lanes parameter

Hello,

I have a fpga connected to xavier nx via 4-lanes CSI. Here is my dtsi for the “camera”.

tegra194-camera-dfccam-tripple.dtsi (60.0 KB)

The problem is that when the num_lanes parameter of camera mode is set to 4 (I suppose it should be 4 when I have 4 lanes CSI) it is not working and I got a lot of errors in trace. However, when I set the num_lanes parameter to 2 it is working and I am able to stream the video out of the module. I would appreciate someone to tell me if there is something wrong with my device tree. Thank you.

Please confirm with sensor vendor for the REG configure is 2 or 4 lanes configure.
