V4L2 driver error

[Zingfrid NoName]

Hello, I need to develop a new camera driver. I've already done a big part, but now I've faced with issue:

 

[   92.374493] rkisp rkisp-vir0: link validation failed for 'rockchip-csi2-dphy0':1 -> 'rkisp-csi-subdev':0, error -32

 

I know, that basically right, as dhy0 has sink pad, and my subdev has only source pad. But I don't know how to change the sides, or avoid it to link in such order. I've already spent a lot of time on this and still no luck. 

 

Do you have any ideas on how to avoid it linking in such order?
