The VIP driver is a V4L2 capture driver that registers /dev/videoX devices in userspace, which are used for performing video capture via standard V4L2 API. The V4L2 specification allows for SoC driver to be written independent of the camera/video source. There is one V4L2 driver for the VIP instance and each camera device may have a separate V4L2 subdevice driver. The camera driver is responsible for configuring the camera as described in the device node and implement some of the media bus operations. Theses operations are often used by the VIP driver whenever the camera needs to perform specific tasks (for example, start/stop camera, get/set fmt, and so forth).
