+* Aptina 1/2.5-Inch 5Mp CMOS Digital Image Sensor
+
+The Aptina MT9P031 is a 1/2.5-inch CMOS active pixel digital image sensor with
+an active array size of 2592H x 1944V. It is programmable through a simple
+two-wire serial interface.
+
+Required Properties:
+- compatible: value should be either one among the following
+ (a) "aptina,mt9p031" for mt9p031 sensor
+ (b) "aptina,mt9p031m" for mt9p031m sensor
+
+- input-clock-frequency: Input clock frequency.
+
+- pixel-clock-frequency: Pixel clock frequency.
+
+Optional Properties:
+- reset-gpios: Chip reset GPIO
+
+For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+ i2c0@1c22000 {
+ ...
+ ...
+ mt9p031@5d {
+ compatible = "aptina,mt9p031";
+ reg = <0x5d>;
+ reset-gpios = <&gpio3 30 0>;
+
+ port {
+ mt9p031_1: endpoint {
+ input-clock-frequency = <6000000>;
+ pixel-clock-frequency = <96000000>;
+ };
+ };
+ };
+ ...
+ };
