Hello again,
I have checked the file you proposed and developed the corresponding dtsi files for the IMX377 sensor.
Using i2cdetect command I can see that the device is detected on the I2C bus. However I still can’t get a frame or connect to the camera for that matter.
I do not have a lot of experience with regards to Linux kernel programming and device tree and I am currently learning on the go.
This is the output of the v4l2-compliance command.

I am pretty sure I have messed up something in the dtsi files but need a little guidance to find out where exactly.
This is the tegra210-camera-imx377-a00.dtsi file.

I have changed the Reset and Power-Down pins as they our different for our board.
In addition I have altered the tegra210-jetson-cv-base-p2597-2180-a00.dts file with the following lines.
//#include "jetson-platforms/tegra210-jetson-cv-camera-modules.dtsi"

Any ideas ?
