I think for the time being we could simply list the compatible devices straight into this binding and forget about referencing this with ref until we have a use case that requires an extension that's not suitable for the generic case (but this is probably highly unlikely as this is for transparent devices, which means that if there is anything missing is probably worth implementing in the generic driver as others may benefit from it). Is this going to require a tidy? For example, should we absorb Documentation/devicetree/bindings/display/bridge/ti,ds90c185.txt ? Also, I have found an undocumented compatible ("ti,sn75lvds83") used in a node with "lvds-encoder" as generic fallback, shall we incorporate that one too? We should also describe powerdown-gpio, somehow its documentation was left behind. Thanks, Fab > > > + ports: > > + type: object > > + description: | > > + This device has two video ports.
