MIPI CSI data format understanding (RAW formats)

I am trying to better understand the MIPI CSI data formats, used in transferring image data from a sensor.

The format specifies the data type that is being transmitted.
example: RAW10, RAW12.

As I understand this common registers setting indicates how and what data is transferred.

example:
csi_data_format[15:0]=0X0C0A
might indicate that 12b (0x0C) data is being converted to 10b (0x0A) data.    to RAW10, I guess.

I'm trying to understand this better and have not found a clear description in any spec.

Thank you in advance, and apologies that this question is not so polished.  Hopefully this is a correct forum for this question.
