According to this MIPI CSI is getting configured and also CSI Bridge is getting IMAGE DATA but CSI Bridge is not enabled and also SOF and EOF Interrupts are disabled .

When I try to Capture using V4L2 I get following 

#https://community.nxp.com/t5/i-MX-Processors/Can-t-able-to-get-V4l2-Sub-dev-in-imx8m-mini/m-p/15177...

Also there is no V4L2 subdevice and media0 in /dev  but I have video

and also when I try to capture it shows success in V4L2 IOCTL but does not give Image

#https://community.nxp.com/t5/i-MX-Processors/Can-t-able-to-get-the-raw-image-in-IMX8M-MINI/m-p/1519...

Attaching Dmesg Log , Device Tree and Driver Codes I'm using .

Don't know what I'm missing ? Pls try to help!
