You don't need to ask. The connector calls invert_vid_out_polarity
before enabling the output.

Unfortunately it doesn’t. At least not always.

It does only for pdata systems but not for DT based systems:

	if (!ddata->dev->of_node) {
		in->ops.atv->set_type(in, ddata->connector_type);
		in->ops.atv->invert_vid_out_polarity(in,
			ddata->invert_polarity);
	}

Not calling is in our case different from calling with ddata->invert_polarity == 0.

Ah, sorry, my mistake. I should've read the code more carefully =).

So, with DT only approach, those calls above are not supported. If you
make the OPA driver DT only, you can remove those functions.

You only need to set the invert-polarity property in the venc DT node.
