The Video Capture Software Stack figure in the Capture section shows how the generic V4L2 driver model of a video pipeline is mapped to the single-sensor MIPI CSI-2 Rx capture pipelines. The video pipeline driver loads the necessary sub-device drivers and registers the device nodes it needs, based on the video pipeline configuration specified in the device tree. The framework exposes the following device node types to user space to control certain aspects of the pipeline:
Media device node: /dev/media*
Video device node: /dev/video*
V4L2 sub-device node: /dev/v4l-subdev*
