  Don't require link-frequencies like it's done for ov5640, that
supports both CSI-2 and DVP. And v4l2_fwnode_endpoint_alloc_parse
ignores link-frequencies property for DVP endpoint. It's used only for
CSI-2 endpoints

Hi Andrey,

Thanks for the patchset.

That seems like a bad idea to me.

While for parallel interface it may not be often important, for CSI-2 it
should stay.

Are there defaults for these if there are no such properties?

You're also missing the bus-type property which should default to CSI-2
D-PHY.

I'll add this type and make link-frequencies required based on that
for CSI-2 bus.

good point. I'll add them to the endpoint properties description then.
