description: |
  The THC63LVD1024 is a dual link LVDS receiver designed to convert LVDS
  streams to parallel data outputs. The chip supports single/dual input/output
  modes, handling up to two LVDS input streams and up to two digital CMOS/TTL
  outputs.

  Single or dual operation mode, output data mapping and DDR output modes are
  configured through input signals and the chip does not expose any control
  bus.

    description: |
      This device has four video ports. Their connections are modeled using the
      OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.

      The device can operate in single or dual input and output modes.

      When operating in single input mode, all pixels are received on port@0,
      and port@1 shall not contain any endpoint. In dual input mode,
      even-numbered pixels are received on port@0 and odd-numbered pixels on
      port@1, and both port@0 and port@1 shall contain endpoints.

      When operating in single output mode all pixels are output from the first
      CMOS/TTL port and port@3 shall not contain any endpoint. In dual output
      mode pixels are output from both CMOS/TTL ports and both port@2 and
      port@3 shall contain endpoints.
