+Omnivision OV5657 raw image sensor
+---------------------------------
+
+OV5657 is a raw image sensor with MIPI CSI-2 and CCP2 image data interfaces
+and CCI (I2C compatible) control bus.
+
+Required properties:
+
+- compatible	: "ov5647";
+- reg		: I2C slave address of the sensor;
+- clocks	: should contain list of phandle and clock specifier pairs
+		  according to common clock bindings for the clocks described
+		  in the clock-names property;
+- clock-names	: should contain "extclk" entry for the sensor's EXTCLK clock;
+
+Optional properties:
+
+- clock-frequency : the frequency at which the "extclk" clock should be
+		    configured to operate, in Hz; if this property is not
+		    specified default 27 MHz value will be used.
+
+The common video interfaces bindings (see video-interfaces.txt) should be
+used to specify link to the image data receiver. The OV5657 device
+node should contain one 'port' child node with an 'endpoint' subnode.
+
+Following properties are valid for the endpoint node:
+
+- data-lanes : (optional) specifies MIPI CSI-2 data lanes as covered in
+  video-interfaces.txt.  The sensor supports only two data lanes.
