8 handles the flow of image frames to and from capture devices and
11 For image capture, the IPU contains the following internal subunits:
21 memory. Various dedicated DMA channels exist for both video capture and
29 The CSI is the backend capture unit that interfaces directly with
62 outside the IPU that are also involved in video capture on i.MX:
79   that correspond to the hardware video capture pipelines supported in
85   video capture interfaces using independent entities.
173 source pad is routed to a capture device node, with a node name of the
174 format "ipuX_csiY capture".
179 If the sink pad is receiving YUV, the output at the capture device can
300 These controls will configure an input capture channel as the method
305 Input capture requires hardware support. A VSYNC signal must be routed
306 to one of the i.MX6 input capture channel pads.
308 V4L2_CID_IMX_FIM_ICAP_CHANNEL configures which i.MX6 input capture
312 input capture events. By default the input capture method is disabled
314 IRQ_TYPE_EDGE_FALLING, or IRQ_TYPE_EDGE_BOTH to enable input capture,
317 When input capture is disabled, frame intervals will be measured via
362 routed to a capture device node, with a node name of the format
363 "ipuX_ic_prpenc capture".
378 to a capture device node, with a node name of the format
379 "ipuX_ic_prpvf capture".

446 capture device interfaces inherit controls from the active entities
448 from the subdev or from the active capture device interface. For
450 subdevs or from the active capture device.
479 The following basic example configures unprocessed video capture
491    media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
495    media-ctl -l "'ipu1_csi1':2 -> 'ipu1_csi1 capture':0[1]"
505 Streaming can then begin independently on the capture device nodes
506 "ipu1_csi0 capture" and "ipu1_csi1 capture". The v4l2-ctl tool can
507 be used to select any supported YUV pixelformat on the capture device
516 The following example configures a pipeline to capture from the ADV7180
530    media-ctl -l "'ipu1_ic_prpvf':1 -> 'ipu1_ic_prpvf capture':0[1]"
539 Streaming can then begin on the capture device node at
540 "ipu1_ic_prpvf capture". The v4l2-ctl tool can be used to select any
541 supported YUV or RGB pixelformat on the capture device node.
559 The following example configures a direct conversion pipeline to capture
572    media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"
580 Streaming can then begin on "ipu1_ic_prpenc capture" node. The v4l2-ctl

588 1. When using 90 or 270 degree rotation control at capture resolutions
590    pixel formats (YUV420, YUV422p), frame capture will often fail with
