+Freescale i.MX Media Video Devices
+Video Media Controller node
+This is the parent media controller node for video capture support.
+Required properties:
+- compatible : "fsl,imx-media";
+- ports      : Should contain a list of phandles pointing to camera
+  	       sensor interface ports of IPU devices
+fim child node
+This is an optional child node of the ipu_csi port nodes. If present and
+available, it enables the Frame Interval Monitor. Its properties can be
+used to modify the method in which the FIM measures frame intervals.
+Refer to Documentation/media/v4l-drivers/imx.rst for more info on the
+Frame Interval Monitor.
+Optional properties:
+- fsl,input-capture-channel: an input capture channel and channel flags,
+			     specified as <chan flags>. The channel number
+			     must be 0 or 1. The flags can be
+			     IRQ_TYPE_EDGE_BOTH, and specify which input
+			     capture signal edge will trigger the input
+			     capture event. If an input capture channel is
+			     specified, the FIM will use this method to
+			     measure frame intervals instead of via the EOF
+			     interrupt. The input capture method is much
+			     preferred over EOF as it is not subject to
+			     interrupt latency errors. However it requires
+			     routing the VSYNC or FIELD output signals of
+			     the camera sensor to one of the i.MX input
+			     capture pads (SD1_DAT0, SD1_DAT1), which also
+			     gives up support for SD1.
+mipi_csi2 node
+This is the device node for the MIPI CSI-2 Receiver, required for MIPI
+CSI-2 sensors.
+Required properties:
+- compatible	: "fsl,imx6-mipi-csi2";
+- reg           : physical base address and length of the register set;
+- clocks	: the MIPI CSI-2 receiver requires three clocks: hsi_tx
+                  (the DPHY clock), video_27m, and eim_sel;
+- clock-names	: must contain "dphy", "cfg", "pix";
+Optional properties:
+- interrupts	: must contain two level-triggered interrupts,
+                  in order: 100 and 101;
