Would you be able to bisect this ?

Sure, the commit the broke camera capture on a imx6ul-evk board was:

    media: imx: imx7-media-csi: Disable legacy video node API

    Support for the MC-centric API has been tested on the i.MX7. Enable it
    for that platform. i.MX6 should be converted next.

If I use your imx/csi/imx7 branch, and then revert the above commit,
camera capture works for me (with the additional patch from me and Rui
as discussed in the other thread).

Ah of course, I should have mentioned that, sorry. Without the legacy
video node API, the pipeline has to be configured with the MC API and
the V4L2 subdev userspace API before starting the stream.
