+i.MX6ULL-EVK with OV5640
+------------------------
+
+On this platform a parallel OV5640 sensor is connected to the CSI port.
+The following example configures a video capture pipeline with an output
+of 640x480 and UYVY8_2X8 format:
+
+.. code-block:: none
+
+   # Setup links
+   media-ctl -l "'ov5640 1-003c':0 -> 'csi':0[1]"
+   media-ctl -l "'csi':1 -> 'csi capture':0[1]"
+
+   # Configure pads for pipeline
+   media-ctl -v -V "'ov5640 1-003c':0 [fmt:UYVY8_2X8/640x480 field:none]"
+
+After this streaming can start:
+
+.. code-block:: none
+
+   gst-launch-1.0 -v v4l2src device=/dev/video1 ! video/x-raw,format=UYVY,width=640,height=480 ! v4l2convert ! fbdevsink
