We have everything working for our custom camera with JETSON NANO but now we are switching to XAXVIER NX. We compared to the example device trees, but we have also device trees from AUVIDEA since we are using their baseboards.
Instead of the examples, the only real difference is the use of cam_i2c_mux, which is not used with AUVIDEA, instead, we use i2c@0c230000 directly.
For some reason I cant figure out, when I probe my driver, the probe function is not invoked like if there was no device compatible with my driver. Do you have any idea, what could be the reason for that? Using standard nvidia device tree I can see the driver being probed.
I’ll leave you with my device tree for the imx219, which is not working.

Am I doing something wrong?
