You're routing through imx6-mipi-csi2 pad 2, which is CSI-2 virtual
channel 1, so make sure the ov5640 is transmitting on that channel,
see virtual_channel module parameter.

I would suggest backporting all the ov5640 commits. You can also
backport the imx-media commits, but that shouldn't be the cause
of the timeouts you are seeing.
