4 MIPI CSI-2 Cameras with Custom carrier board

We created a custom carrier board with 4 cameras.
The cameras are IMX219 with 2 lanes each one.
We used the CSI-A , C, E and F. This means: port-index: 0,2,4 and 5. For CSI and VI.

We have a TCA9584 with each camera connected to the ports 0, 1, 2 and 3.

We connected the CAM1_MCLK to 2 cameras and the CAM2_MCLK to other 2 cameras.

We have connected individual PW_DN for each camera.
I’m attaching my DTS for the cameras.

The error that we have is:

The good point is using the DUAL-imx219 dtb, and using i2cset -y 6 0x70 0x0f we have access to 2 cameras simultaneously without problem.
But never I have access with the TCA9584 i2c_mux.

Does this error impact the sensor driver register video node?
Check if v4l2-ctl --list-devices to clarify the sensor driver been loaded.

Hi, finally was solved. the mistake was in the device tree configuration. now our board lita carrier board are working with 4 cameras correctly using Jetson NANO production module and we are working to have the same with the XAVIER NX. Thanks!
