+* Aptina 1/3-Inch WVGA CMOS Digital Image Sensor
+
+The Aptina MT9V032 is a 1/3-inch CMOS active pixel digital image sensor with
+an active array size of 752H x 480V. It is programmable through a simple
+two-wire serial interface.
+
+Required Properties:
+
+- compatible: value should be either one among the following
+       (a) "aptina,mt9v022" for MT9V022 color sensor
+       (b) "aptina,mt9v022m" for MT9V022 monochrome sensor
+       (c) "aptina,mt9v024" for MT9V024 color sensor
+       (d) "aptina,mt9v024m" for MT9V024 monochrome sensor
+       (e) "aptina,mt9v032" for MT9V032 color sensor
+       (f) "aptina,mt9v032m" for MT9V032 monochrome sensor
+       (g) "aptina,mt9v034" for MT9V034 color sensor
+       (h) "aptina,mt9v034m" for MT9V034 monochrome sensor
+
+Optional Properties:
+
+- link-frequencies: List of allowed link frequencies in Hz. Each frequency is
+       expressed as a 64-bit big-endian integer.
+
+For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+       mt9v032@5c {
+               compatible = "aptina,mt9v032";
+               reg = <0x5c>;
+
+               port {
+                       mt9v032_out: endpoint {
+                               link-frequencies = /bits/ 64
+                                       <13000000 26600000 27000000>;
+                       };
+               };
+       };
