Hi Sakari,
Thank you very much for your review and advice.
I will send a new version to fix it.

+* Omnivision OV7740 CMOS image sensor
+
+The Omnivision OV7740 image sensor supports multiple output image
+size, such as VGA, and QVGA, CIF and any size smaller. It also
+supports the RAW RGB and YUV output formats.
+
+Required Properties:
+- compatible: should be "ovti,ov7740"
+- clocks: reference to the xvclk input clock.
+- clock-names: should be "xvclk".
+
+Optional Properties:
+- reset-gpios: reference to the GPIO connected to the reset_b pin,
+ if any. Active low with pull-ip resistor.
+- powerdown-gpios: reference to the GPIO connected to the pwdn pin,
+ if any. Active high with pull-down resistor.
+
+The device node must contain one 'port' child node for its digital
+output video port, in accordance with the video interface bindings
+defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
Could you add there's a single endpoint node as well, and explicitly
document the relevant properties? E.g. as in
Documentation/devicetree/bindings/media/i2c/nokia,smia.txt .
+
+Example:
+
+ i2c1: i2c@fc028000 {
+ ov7740: camera@21 {
+ compatible = "ovti,ov7740";
+ reg = <0x21>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_sensor_power &pinctrl_sensor_reset>;
+ clocks = <&isc>;
+ clock-names = "xvclk";
+ assigned-clocks = <&isc>;
+ assigned-clock-rates = <24000000>;
+ reset-gpios = <&pioA 43 GPIO_ACTIVE_LOW>;
+ powerdown-gpios = <&pioA 44 GPIO_ACTIVE_HIGH>;
+
+ port {
+ ov7740_0: endpoint {
+ remote-endpoint = <&isc_0>;
+ };
+ };
+ };
+ };
