IMX8QM MIPI CSI : Cannot link with subdev

[johnjacob]

Dear Experts,

We are working on a customer board based on imx8 quad max. We are facing issues with the bring up of AR0144AT +DS90UB960+913A(SerDes combo).

We are able to detect the sensor but unable to successfully link the sensor to a CSI interface ( CSI0).

We tried adding missing callbacks for link_setup in the driver for the "subdev_notifier_complete error exit" still no luck.

Kindly help us in solving the linking issue on the csi interfacing. 

Best,

John

Hi @johnjacob,

Could you please provide me with the callback function which you added?

Best Regards,
Dhruvit.
