[PATCH 2/4] dt-bindings: display: bridge: Convert simple-bridge bindings to YAML

[Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>]

The simple-bridge driver supports multiple simple or dumb bridges,
covered by different compatible strings but otherwise identical DT
bindings. Some of those bridges have undocumented bindings, while others
are documented in text form in separate files. Group them all in a
single binding and convert it to YAML.

-Analog Device ADV7123 Video DAC
--------------------------------
-
-The ADV7123 is a digital-to-analog converter that outputs VGA signals from a
-parallel video input.
-
-Required properties:
-
-- compatible: Should be "adi,adv7123"
-
-Optional properties:
-
-- psave-gpios: Power save control GPIO
-
-Required nodes:
-
-The ADV7123 has two video ports. Their connections are modeled using the OF
-graph bindings specified in Documentation/devicetree/bindings/graph.txt.
-
-- Video port 0 for DPI input
-- Video port 1 for VGA output
-
-
-Example
--------
-
-	adv7123: encoder@0 {
-		compatible = "adi,adv7123";
-
-		ports {
-			#address-cells = <1>;
-			#size-cells = <0>;
-
-			port@0 {
-				reg = <0>;
-
-				adv7123_in: endpoint@0 {
-					remote-endpoint = <&dpi_out>;
-				};
-			};
-
-			port@1 {
-				reg = <1>;
-
-				adv7123_out: endpoint@0 {
-					remote-endpoint = <&vga_connector_in>;
-				};
-			};
-		};
