+Micron 1.3Mp CMOS Digital Image Sensor
+
+The Micron MT9M111 is a CMOS active pixel digital image sensor with an active
+array size of 1280H x 1024V. It is programmable through a simple two-wire serial
+interface.
+
+Required Properties:
+- compatible: value should be "micron,mt9m111"
+
+For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+       i2c_master {
+               mt9m111@5d {
+                       compatible = "micron,mt9m111";
+                       reg = <0x5d>;
+
+                       remote = <&pxa_camera>;
+                       port {
