[PATCH 0/2] dt-bidings: media: ov5647 bindings + small fix

[Jacopo Mondi]

While converting the ov5647 bindings to dt-schema I noticed the remote-endpoint
property was not documented in the only 2 existing image sensor bindings.

Convert the ov5647 bindings and add remote-endpoint as required property to
the existing ones.

-Omnivision OV5647 raw image sensor
----------------------------------
-
-OV5647 is a raw image sensor with MIPI CSI-2 and CCP2 image data interfaces
-and CCI (I2C compatible) control bus.
-
-Required properties:
-
-- compatible		: "ovti,ov5647".
-- reg			: I2C slave address of the sensor.
-- clocks		: Reference to the xclk clock.
-
-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.
-
-Endpoint node mandatory properties:
-
-- remote-endpoint: A phandle to the bus receiver's endpoint node.
-
-Example:
-
-	i2c@2000 {
-		...
-		ov: camera@36 {
-			compatible = "ovti,ov5647";
-			reg = <0x36>;
-			clocks = <&camera_clk>;
-			port {
-				camera_1: endpoint {
-					remote-endpoint = <&csi1_ep1>;
-				};
-			};
-		};
-	};

[PATCH 2/2] dt-bindings: media: i2c: Document 'remote-endpoint'

[Jacopo Mondi]

Document the 'remote-endpoint' property and add it to the list of required
endpoint properties in imx219 and ov8856 dt-schema binding files.
