The media controller pipeline graph is as follows:

.. _starfive_camss_graph:

.. kernel-figure:: starfive_camss_graph.dot :alt: starfive_camss_graph.dot :align: center

The driver has 2 video devices:

  • capture_raw: The capture device, capturing image data directly from a sensor.
  • capture_yuv: The capture device, capturing YUV frame data processed by the ISP module

The driver has 3 subdevices:

  • stf_isp: is responsible for all the isp operations, outputs YUV frames.
  • cdns_csi2rx: a CSI-2 bridge supporting up to 4 CSI lanes in input, and 4 different pixel streams in output.
  • imx219: an image sensor, image data is sent through MIPI CSI-2.
