+* Aptina MT9V111 CMOS sensor
+----------------------------
+
+The Aptina MT9V111 is a 1/4-Inch VGA-format digital image sensor with a core
+based on Aptina MT9V011 sensor and an integrated Image Flow Processor (IFP).
+
+The sensor has an active pixel array of 649x489 pixels and can output a number
+of image resolution and formats controllable through a simple two-wires
+interface.
+
+Required properties:
+--------------------
+
+- compatible: shall be "aptina,mt9v111".
+- clocks: reference to the system clock input provider.
+
+Optional properties:
+--------------------
+
+- enable-gpios: output enable signal, pin name "OE#". Active low.
+- standby-gpios: low power state control signal, pin name "STANDBY".
+  Active high.
+- reset-gpios: chip reset signal, pin name "RESET#". Active low.
+
+The device node must contain one 'port' child node with one 'endpoint' child
+sub-node for its digital output video port, in accordance with the video
+interface bindings defined in:
+Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+--------
+
+        &i2c1 {
+                camera@48 {
+                        compatible = "aptina,mt9v111";
+                        reg = <0x48>;
+
+                        clocks = <&camera_clk>;
+
+                        port {
+                                mt9v111_out: endpoint {
+                                        remote-endpoint = <&ceu_in>;
+                                };
+                        };
+                };
+        };
