| 12 | description: |
| 13 | The ADV7604 and ADV7610/11/12 are multiformat video decoders with |
| 14 | an integrated HDMI receiver. The ADV7604 has four multiplexed HDMI inputs |
| 15 | and one analog input, and the ADV7610/11 have one HDMI input and no analog |
| 16 | input. The ADV7612 is similar to the ADV7610/11 but has 2 HDMI inputs. |
| 17 | |
| 18 | These device tree bindings support the ADV7610/11/12 only at the moment. |
