+MT9M001: 1/2-Inch Megapixel Digital Image Sensor
+
+The MT9M001 is an SXGA-format with a 1/2-inch CMOS active-pixel digital
+image sensor. It is programmable through a simple two-wire serial
+interface.
+
+Required Properties:
+
+- compatible: shall be "onnn,mt9m001".
+- clocks: reference to the master clock into sensor
+
+Optional Properties:
+
+- reset-gpios: GPIO handle which is connected to the reset pin of the chip.
+ Active low.
+- standby-gpios: GPIO handle which is connected to the standby pin of the chip.
+ Active high.
+
+For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+ &i2c1 {
+ mt9m001@5d {
+ compatible = "onnn,mt9m001";
+ reg = <0x5d>;
+ reset-gpios = <&gpio0 0 GPIO_ACTIVE_LOW>;
+ standby-gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
+ clocks = <&camera_clk>;
+ port {
+ mt9m001_out: endpoint {
+ remote-endpoint = <&vcap_in>;
+ };
+ };
+ };
+ };
