Is "xclk" clock a pixel clock or something else?
+- clock-names : Should be "xclk".
You can remove this property, because there is only one source clock.
+- clock-frequency : Frequency of the xclk clock.
And after the last updates in the driver this property can be removed as well.

+The common video interfaces bindings (see video-interfaces.txt) should be
+used to specify link to the image data receiver. The OV5647 device
+node should contain one 'port' child node with an 'endpoint' subnode.

+Example:
+
+ i2c@2000 {
+ ...
+ ov: camera@36 {
+ compatible = "ovti,ov5647";
+ reg = <0x36>;
+ clocks = <&camera_clk>;
+ clock-names = "xclk";
+ clock-frequency = <25000000>;When you remove two unused properties, please don't forget to update the example.
