Thanks @joanxie for the response. Those are what we've used as our references. Unfortunately I'm seeing a hang when trying to enable the mipi gclk - seen in this function:
mipi_csis_imx8mn_gclk_enable
I'm looking into whether we've setup our clock lines correctly, but if you have any insights on this, please let me know. Thanks!
For reference here are the notable DTS nodes we're using:
