I think this might be worth a new comment to tell what devices can be found here --- it's not a camera sensor as such really. But I wonder how should it be called.

Oh, sorry; I missed that.

I don't remember all the details, but my understanding is that RDACM20 is much more than just a box that contains the serialiser and the sensors. So very probably it'll need its own driver, too. Powering on the sensors, for instance, seemed hard to make generic. > > As the RDACM20 is an object itself, I think this makes sense ... unless > anyone suggests that each part should be broken down into the DT > directly ?
