What about to split csi_streaming() into csi_start_streaming() /
csi_stop_streaming()?

This will make tegra_csi_ops to be consistent with the tegra_ve_ops. A
separated start/stop operations are somewhat more natural to have in
general.

vi ops is for vb2_ops which has separate start/stop so has seperate start/stop for vi ops.

csi is subdev and csi ops is for v4l2_subdev_ops which as s_stream callback only.

So, created single stream function for csi to match same as subdev_ops.
