Ah, I missed Gose is using "adi,adv7180cp", while Lager, Koelsch, Porter, Alt, and Silk are using "adi,adv7180". Next question: why the difference? Gose and Koelsch should be identical w.r.t. these interfaces. In fact all boards listed above are using ADV7180WBCP32Z, and seem to use similar wiring. What's happening? Thanks!

The difference as far as I can tell is only in the bindings. The older 'adi,adv7180' compatibility string only describes where the adv7180 is transmitting the data it collects from an undescribed connector. While the more recent compat string 'adi,adv7180cp' describes both the destination and the connector. A good example as you point out is to compare koelsch with gose. From a V4L2 point of view the connector being described does not effect the capture operation. Ulrich maybe you can help us shed some light on this as you added the new compat strings? > > What's happening?

Executive summary: "[Laurent and Hans] agreed that DT should model physical ports." Full details: https://www.mail-archive.com/linux-media@vger.kernel.org/msg103799.html The reason why it's only in Gose is that that was the patch series that raised the issue, and we didn't update the existing implementations.
