Hi, Here is an attempt at supporting the MIPI-CSI2 RX block from Cadence. This IP block is able to receive CSI data over up to 4 lanes, and split it to over 4 streams. Those streams are basically the interfaces to the video grabbers that will perform the capture. It is able to map streams to both CSI datatypes and virtual channels, dynamically. This is unclear at this point what the right way to support it would be, so the driver only uses a static mapping between the virtual channels and streams, and ignores the data types. This serie depends on the version 5 of the serie "v4l2-async: add subnotifier registration for subdevices" from Niklas Söderlund. Let me know what you think!
