+* Omnivision OV5695 MIPI CSI-2 sensor

+Required Properties:
+- compatible: shall be "ovti,ov5695"
+- clocks: reference to the xvclk input clock
+- clock-names: shall be "xvclk"
+- avdd-supply: Analog voltage supply, 2.8 volts
+- dovdd-supply: Digital I/O voltage supply, 1.8 volts
+- dvdd-supply: Digital core voltage supply, 1.2 volts
+- reset-gpios: Low active reset gpio

+The device node shall contain one 'port' child node with an
+'endpoint' subnode for its digital output video port,
+in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+The endpoint optional property 'data-lanes' shall be "<1 2>".
What happens if the property is not present? What's the default?
I think it depends on how the video receiver deal with, 'data-lanes' is
optional as described in video-interfaces.txt,
but if somehow it used in DT, the value "<1 2>" is the right one.
I would:
Required Properties:
- compatible: ..
....
Option Endpoint Properties:
- data-lanes: ...
+
+Example:
+&i2c7 {
+ camera-sensor: ov5695@36 {
You have inverted the label with the node name which should be generic
ov5695: camera@36 {
}
Thanks

Thank you very much~
