Sure, the discussion will be continued abouve v9 of the series, it's
just a chance to do it now. Rob properly pointed out, that the invented
"phy-type" is not needed at all.
Ther fact is that the whole placement of the CSIPHY to phy subsystem
looks execessive, since you add a driver for a media device, there will
be nothing PHY driver specific left in the CSIPHY driver but name.
