| 2 | ------------------------------- |
| 3 | |
| 4 | The ADV7123 is a digital-to-analog converter that outputs VGA signals from a |
| 5 | parallel video input. |
| 6 | |
| 7 | Required properties: |
| 8 | |
| 9 | - compatible: Should be "adi,adv7123" |
| 10 | |
| 11 | Optional properties: |
| 12 | |
| 13 | - psave-gpios: Power save control GPIO |
| 14 | |
| 15 | Required nodes: |
| 16 | |
| 17 | The ADV7123 has two video ports. Their connections are modeled using the OF |
| 18 | graph bindings specified in Documentation/devicetree/bindings/graph.txt. |
| 19 | |
| 20 | - Video port 0 for DPI input |
| 21 | - Video port 1 for VGA output |
| 22 | |
| 23 | |
| 24 | Example |
| 25 | ------- |
| 26 | |
| 27 | adv7123: encoder@0 { |
| 28 | compatible = "adi,adv7123"; |
| 29 | |
| 30 | ports { |
| 31 | #address-cells = <1>; |
| 32 | #size-cells = <0>; |
| 33 | |
| 34 | port@0 { |
| 35 | reg = <0>; |
| 36 | |
| 37 | adv7123_in: endpoint@0 { |
| 38 | remote-endpoint = <&dpi_out>; |
| 39 | }; |
| 40 | }; |
| 41 | |
| 42 | port@1 { |
| 43 | reg = <1>; |
| 44 | |
| 45 | adv7123_out: endpoint@0 { |
| 46 | remote-endpoint = <&vga_connector_in>; |
| 47 | }; |
| 48 | }; |
| 49 | }; |
| 50 | }; |
