Driver support method for parallel input to CRU

Hello Renesas Community,

We are developing a custom board using the RZ/G2L.
The output signal of the camera unit is input to the RZ/G2L in parallel for the CRU. (YUV422_16bit)
MIPI-CSI is not used.
The camera unit automatically outputs video after the system is powered on, so no control from the RZ/G2L is required.
Therefore, we believe that I2C drivers such as sensor drivers are not necessary.

I'm trying to create a dts file using the following as a reference, but /dev/video0 is not created.
There is no evidence in the kernel log that the CRU driver has been loaded.

 Accessing Digital Parallel Interface for camera module instead of MIPI. 

I think I need to install some kind of dummy sensor driver so that /dev/video0 can be created.
With this system configuration, could you please tell me how to support the kernel in order to input parallel to the CRU?

Regards.
