+Toshiba et8ek8 5MP sensor
+
+Toshiba et8ek8 5MP sensor is an image sensor found in Nokia N900 device
+
+More detailed documentation can be found in
+Documentation/devicetree/bindings/media/video-interfaces.txt .
+
+
+Mandatory properties
+--------------------
+
+- compatible: "toshiba,et8ek8"
+- reg: I2C address (0x3e, or an alternative address)
+- vana-supply: Analogue voltage supply (VANA), 2.8 volts
+- clocks: External clock to the sensor
+- clock-frequency: Frequency of the external clock to the sensor. Camera
+  driver will set this frequency on the external clock.
+- reset-gpios: XSHUTDOWN GPIO
+
+
+Endpoint node mandatory properties
+----------------------------------
+
+- remote-endpoint: A phandle to the bus receiver's endpoint node.
+
+Endpoint node optional properties
+----------------------------------
+
+- clock-lanes: <0>
+- data-lanes: <1..n>
+
+Example
+-------
+
+&i2c3 {
+	clock-frequency = <400000>;
+
+	cam1: camera@3e {
+		compatible = "toshiba,et8ek8";
+		reg = <0x3e>;
+		vana-supply = <&vaux4>;
+		clocks = <&isp 0>;
+		clock-frequency = <9600000>;
+		reset-gpio = <&gpio4 6 GPIO_ACTIVE_HIGH>; /* 102 */
+		port {
+			csi_cam1: endpoint {
+				remote-endpoint = <&csi_out1>;
+			};
+		};
+	};
+};
