On one particular revision of this module, one can also directly use the RGB interface. Would it be better to model this as bridge+panel? We already have a binding for the RGB version [1]. This would make it harder to make a driver though, as there is no publicly available datasheet for the bridge chip, so it's likely that part of the init sequence would have to be hard-coded. Thanks ChenYu [1] Documentation/devicetree/bindings/display/panel/bananapi,s070wv20-ct16.txt
