Analog TV Connector

===================



Required properties:

- compatible: "composite-video-connector" or "svideo-connector"



Optional properties:

- label: a symbolic name for the connector

- sdtv-standards: limit the supported TV standards on a connector to the given

                  ones. If not specified all TV standards are allowed.

                  Possible TV standards are defined in

                  include/dt-bindings/display/sdtv-standards.h.



Required nodes:

- Video port for TV input



Example

-------

#include <dt-bindings/display/sdtv-standards.h>



tv: connector {

	compatible = "composite-video-connector";

	label = "tv";

	sdtv-standards = <(SDTV_STD_PAL | SDTV_STD_NTSC)>;



	port {

		tv_connector_in: endpoint {

			remote-endpoint = <&venc_out>;

		};

	};

};

DVI Connector

==============



Required properties:

- compatible: "dvi-connector"



Optional properties:

- label: a symbolic name for the connector

- ddc-i2c-bus: phandle to the i2c bus that is connected to DVI DDC

- analog: the connector has DVI analog pins

- digital: the connector has DVI digital pins

- dual-link: the connector has pins for DVI dual-link

- hpd-gpios: HPD GPIO number



Required nodes:

- Video port for DVI input



Note: One (or both) of 'analog' or 'digital' must be set.



Example

-------



dvi0: connector@0 {

	compatible = "dvi-connector";

	label = "dvi";



	digital;



	ddc-i2c-bus = <&i2c3>;



	port {

		dvi_connector_in: endpoint {

			remote-endpoint = <&tfp410_out>;

		};

	};
