Hi!

+		imx219_ep: endpoint {
+			clock-lanes = <0>;
+			data-lanes = <1 2>;
+			link-frequencies = /bits/ 64 <456000000>;
+			/* uncomment remote-endpoint property to tie imx219 to
+			 * CSI2 also make sure remote-endpoint for ov5645 camera
+			 * is commented and remote endpoint phandle in csi40_in
+			 * is imx219_ep
+			 */

This needs to be normal comment style, and it needs to contain
sentences. And it may be better to provide #ifdef for the alternate
configuration.

+			/* remote-endpoint = <&csi40_in>; */

Best regards,
							Pavel
