Hi,
Tested on gateworks ventana and variscite dart platform :
Unable to bind ipu1_csi0 on ipu1_vdic AND ipu2_csi1 on ipu2_vdic.
Steps to reproduce on ventana board :
$ media_ctl -p
- entity 53: ipu1_csi0 (3 pads, 4 links)
type V4L2 subdev subtype Unknown flags 0
device node name /dev/v4l-subdev8
pad0: Sink

Others links works great.
The ipu -> vdic bind worked on 4.14
Is it a kernel bug?
