i fixed RGB fpga chips and fixing wrong codes and enabled rgb888

I asked that and the FPGA sides answered that ’ we got nothing to wrong and check your SW settings’.
The HW and FPGA said video data is sending and serdes registers setting is works.
but data isnt coming. so i want to check DT for CSI and MIPI settings.

Anyway i have questions about serdes and csi .

my question is

  • Can I using Virtual Channel?
    reference using vc and i had same setting too. but my custom device is get yuvu and rgb888 data from serdes (max9296, max9295) .
    YUV is 16 bit and RGB is 24 bits so is it have to using different csi port on gmsl-link ?
    and how to changing that?

// remains for others
i read threads and changed Device tree and added rgb888.
