Referred above link to port the jd9365da driver and dts file for above jd9365da driver is prepared by myself and attached it in the link given below for reference.
Please check the link given below for the patches i ported for imx8 core board.

Even the probe() in jd9365da driver is failed to trigger during board bring up , could you please provide some insights for further debugging on the issue.?
