This is a media entity subdevice driver for the i.MX Sensor Multi-FIFO
Controller module. Video frames are received from the CSI and can
be routed to various sinks including the i.MX Image Converter for
scaling, color-space conversion, motion compensated deinterlacing,
and image rotation.

I'd prefer to keep them on separate lines, to indicate they
are all built as separate modules.
