The controller uses a separate D-PHY, which is the same that is otherwise used for MIPI DSI, but used in Rx mode. On the V3s, the CSI0 controller is dedicated to MIPI CSI-2 as it does not have access to any parallel interface pins. Add all the necessary nodes (CSI0, MIPI CSI-2 bridge and D-PHY) to support the MIPI CSI-2 interface. Note that a fwnode graph link is created between CSI0 and MIPI CSI-2 even when no sensor is connected. This will result in a probe failure for the controller as long as no sensor is connected but this is fine since no other interface is available. The interconnects property is used to inherit the proper DMA offset.

Even though it is very close to the A31 ISP, it is not exactly register-compatible and a dedicated compatible only is used as a result. Just like most other blocks of the camera pipeline, the ISP uses the common CSI bus, module and ram clock as well as reset. A port connection to the ISP is added to CSI0 for convenience since CSI0 serves for MIPI CSI-2 interface support, which is likely to receive raw data that will need to be processed by the ISP to produce a final image. The interconnects property is used to inherit the proper DMA offset.
