12description:
13  The ADV7604 and ADV7611/12 are multiformat video decoders with an integrated
14  HDMI receiver. The ADV7604 has four multiplexed HDMI inputs and one analog
15  input, and the ADV7611 has one HDMI input and no analog input. The 7612 is
16  similar to the 7611 but has 2 HDMI inputs.
17
18  These device tree bindings support the ADV7611/12 only at the moment.
