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.

      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-link mode or dual-link mode. In
      single-link mode, all pixels are received on port@0, and port@1 shall not
      contain any endpoint. In dual-link 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.
