Should be set to something like 'platform:imx-media-camif'. v4l2-compliance
should
complain about this.
Right, I've fixed this already as part of v4l2-compliance testing.

Set device_caps in struct video_device, then drop these two lines since
the core will set these up based on the device_caps field in struct
video_device.
done.

Wrong op, use g_tvnorms instead.
done.
