title: Analog Devices ADV7604/10/11/12 video decoder with HDMI receiver

maintainers:
  - Hans Verkuil <hverkuil@kernel.org>

description:
  The ADV7604 and ADV7610/11/12 are multiformat video decoders with
  an integrated HDMI receiver. The ADV7604 has four multiplexed HDMI inputs
  and one analog input, and the ADV7610/11 have one HDMI input and no analog
  input. The ADV7612 is similar to the ADV7610/11 but has 2 HDMI inputs.

  These device tree bindings support the ADV7610/11/12 only at the moment.
