- * Stream management
- *
- * Every ISP pipeline has a single input and a single output. The input can be
- * either a sensor or a video node. The output is always a video node.
- *
- * As every pipeline has an output video node, the ISP video objects at the
- * pipeline output stores the pipeline state. It tracks the streaming state of
- * both the input and output, as well as the availability of buffers.
- *
- * In sensor-to-memory mode, frames are always available at the pipeline input.
- * Starting the sensor usually requires I2C transfers and must be done in
- * interruptible context. The pipeline is started and stopped synchronously
- * to the stream on/off commands. All modules in the pipeline will get their
- * subdev set stream handler called. The module at the end of the pipeline must
- * delay starting the hardware until buffers are available at its output.
- *
- * In memory-to-memory mode, starting/stopping the stream requires
- * synchronization between the input and output. ISP modules can't be stopped
- * in the middle of a frame, and at least some of the modules seem to become
- * busy as soon as they're started, even if they don't receive a frame start
- * event. For that reason frames need to be processed in single-shot mode. The
- * driver needs to wait until a frame is completely processed and written to
- * memory before restarting the pipeline for the next frame. Pipelined
- * processing might be possible but requires more testing.
- *
- * Stream start must be delayed until buffers are available at both the input
- * and output. The pipeline must be started in the videobuf queue callback with
- * the buffers queue spinlock held. The modules subdev set stream operation must
- * not sleep.
