Commit 4791bd7d6adc ("media: imx: Try colorimetry at both sink and
source pads") reworked the way that formats are set on the sink pad of
the CSI subdevice, and accidentally removed video field handling.
Restore it by defaulting to V4L2_FIELD_NONE if the field value isn't
supported, with the only two supported value being V4L2_FIELD_NONE and
V4L2_FIELD_ALTERNATE.
I think you mean the only two supported field values being
V4L2_FIELD_NONE and V4L2_FIELD_INTERLACED.
For this driver to support ALTERNATE, it would have to detect the
captured field type and place that type in the returned vb2 buf->field,
which it is not doing.
