MIPI-CSI can´t support raw data.
The available data types can be found on chapter 46.3.3 from the reference manual.
Possible workaround is:
Use an ISP convert chip, eg, AP1302, convert the raw to MIPI CSI interface, then connect to RT1170 MIPI CSI. it might be considered by you since this implies adding a component to your solution.
