CAL has 8 DMA-engines and can capture 8 separate streams at the same time. The driver filters the streams based on CSI-2 virtual channel number and datatype. CAL may have (depending on the SoC) two CSI-2 RX blocks, which share the 8 DMA-engines, so the number of capturable streams does not change even if there are two CSI-2 RX blocks. Add 8 video device nodes, each representing a single DMA-engine, and set the number of source pads on CSI-2 RX blocks to 8. Each video node can be connected to any of the source pads on either of the CSI-2 RX instances using media links. CSI-2 RX block's subdevice internal routing is used to route the incoming CSI-2 streams to one of the 8 source pads. Only video data streams are supported at the moment.
