Some Allwinner devices come with an Image Signal Processor (ISP) that allows processing camera data to produce good-looking images, especially from raw bayer representations. The ISP does not have a dedicated capture path: it is fed directly by one of the CSI controllers, which can be selected at run-time. Represent this possibility as a graph connection between the CSI controller and the ISP in the device-tree bindings.
