CSI-2 is a data bus intended for transferring images from cameras tothe host SoC. It is defined by the MIPI alliance.
13.1. Transmitter drivers¶
Mipi Csi 2 Specification Pdf Signer
CSI-2 transmitter, such as a sensor or a TV tuner, drivers need toprovide the CSI-2 receiver with information on the CSI-2 busconfiguration. These include the V4L2_CID_LINK_FREQ andV4L2_CID_PIXEL_RATE controls and(v4l2_subdev_video_ops->s_stream() callback). Theseinterface elements must be present on the sub-device represents theCSI-2 transmitter.
The V4L2_CID_LINK_FREQ control is used to tell the receiver driver thefrequency (and not the symbol rate) of the link. TheV4L2_CID_PIXEL_RATE is may be used by the receiver to obtain the pixelrate the transmitter uses. Thev4l2_subdev_video_ops->s_stream() callback provides anability to start and stop the stream.
The value of the V4L2_CID_PIXEL_RATE is calculated as follows:
where
| variable or constant | description |
|---|---|
| link_freq | The value of the V4L2_CID_LINK_FREQ integer64 menu item. |
| nr_of_lanes | Number of data lanes used on the CSI-2 link. This canbe obtained from the OF endpoint configuration. |
| 2 | Two bits are transferred per clock cycle per lane. |
| bits_per_sample | Number of bits per sample. |
The transmitter drivers must configure the CSI-2 transmitter to LP-11mode whenever the transmitter is powered on but not active. Sometransmitters do this automatically but some have to be explicitlyprogrammed to do so.

13.2. Receiver drivers¶
Mipi Csi 2 Specification Pdf Download
Before the receiver driver may enable the CSI-2 transmitter by usingthe v4l2_subdev_video_ops->s_stream(), it must have poweredthe transmitter up by using thev4l2_subdev_core_ops->s_power() callback. This may takeplace either indirectly by using v4l2_pipeline_pm_use() ordirectly.
