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.
